How Test Sequence Affects Environmental Test Results

28/09/2026

Two identical products, same test list, same severities — but different results simply because the order of execution is different. This is something that is often overlooked when planning environmental testing.

This article explains why test sequence is part of the test definition, ordering principles, and what needs to be agreed upon before starting.

1. Why sequence matters

Three mechanisms cause order to alter results:

Cumulative:The former test produces small damage, the latter amplifies it into obvious damage. Vibration testing after the sample has been cracked by thermal cycling gives much worse results than vibration testing on the intact sample.
Masking:The following test erases the traces of the previous test. Testing water after dust testing may wash away dust and remove evidence of intrusion.
Material Variation:High temperatures can change the state of the material (stress relaxation, coating transformation), causing subsequent cold testing to no longer accurately evaluate the original material.

Consequence: if the required document clearly states the test sequence, the operator cannot change the order himself. If the documents do not clearly state, it is necessary to agree in writing before testing.

2. General ordering principles

Don’t destroy first, destroy later.Mild or non-destructive tests should be reserved to utilize the same sample.
Climate before mechanics.A common sequence is temperature/humidity first, vibration and shock second, as moisture and thermal cycling can weaken the joint before vibration accelerates damage.
Avoid cross contamination.Corrosion, dust, and solvent tests contaminate the chamber and sample; If performed in advance, they may affect later tests.
Test the function at a meaningful point.Check after each step or group of steps, depending on the assessment goal.
The final test should be one where the trace is clearly observed.For example, checking for corrosion, cracking, and deformation requires the sample to have its surface intact.

Buồng thử khí hậu và khu vực chuẩn bị mẫu trong phòng thử nghiệm môi trường — The order of testing determines the results, so it needs to be clearly stated in the requirements document, not just agreed upon verbally.

3. A typical reference sequence

Step	Test group	Reason for placing in this position
1	Initial check: appearance, function, parameters	Set a benchmark before testing
2	Dry heat/cold (Test B, Test A)	Non-destructive, shared samples, basic heat resistance test
3	Temperature change (Test N)	Apply thermal stress to the joint and material, preparing for the following steps
4	Stable humidity/heat cycle (Cab, Db)	Causes moisture and condensation — causes of insulation degradation
5	Vibration and shock (Fc/Fh, Ea)	After the joint has been subjected to thermal-humidity stress, vibration amplifies potential damage
6	Rough handling, falling (Ec)	Simulate the transportation and loading stages
7	Corrosion (Ka/Kb, Kc/Kd/Ke)	Place it last with the climate-mechanical group to observe corrosion traces on the sample that has been subjected to stress
8	Final inspection and evaluation	Compare with the initial milestone according to the agreed criteria

This is a reference string, not a mandatory regulation. The actual sequence must come from the usage environment: if the product is shipped before installation, it may be necessary to bring the roughing group up first.

4. Ordering pairs that cause disagreement

Pair	Commonly used order	Reason
Damp heat and salt mist	Hot humidity first, frost later	Salt mist leaves salt residue that affects moisture testing; Conversely, prewetting helps evaluate corrosion in conditions where a wet film has formed
Vibration and salt mist	Depends on the goal	If you want to evaluate corrosion at cracked joints, do a vibration test first; If you want to evaluate mechanical durability in a corrosive environment, put corrosion first
Welding heat and other environmental testing	Final soldering heat (with components)	The welding process changes the material state, which should not precede initial material evaluation tests
Dust and water	Dust first, water later — but it must be clearly stated	Water can wash away dust; If evidence of dust intrusion is required, this must be checked and recorded before water testing

Bàn thử rung với mẫu được gá lắp và cảm biến đo — In many series, vibration is applied after climatic tests to detect potential damage.

5. Where functional examinations belong in the sequence

Before string:required, to have a benchmark for comparison. Without a baseline, deterioration cannot be concluded.
After each step:suitable when it is necessary to determine which step causes damage — for design analysis.
After group of steps:suitable for qualitative testing, lower cost but loss of causality.
During the test:Some tests require continuous functional monitoring or parameter measurements at extreme temperatures; need to be clearly defined from the beginning.

6. When the sequence can be shortened

Can be shortened when the goal is rapid screening (e.g. batch inspection), when the product already has data from previous tests, or when the risk level is low and the customer agrees. Should not be shortened when:

The results are used to declare conformity or certify according to standards that define their own sequences.
Customers require the correct string according to their documents.
The goal is to find the cause of the failure — at which point it is necessary to try to isolate each factor.

7. Common mistakes

Change the order for convenient operationwithout recording — causing the results to no longer match the requirements.
Use the same template for all stepswhen the documentation requires a separate sample for each test.
Do not check appearance between steps,leading to loss of evidence of when the damage occurred.
Do not clean the chamber between test groups.cause cross contamination.
Ignore recovery conditions,causes the following test to start while the sample is still in the unfinished state.

Hồ sơ ghi chép dữ liệu và mẫu thử sau khi thử nghiệm môi trường — Recording the order of execution, when to test, and the results of each step is the only way to protect your conclusions later.

8. Frequently asked questions

What if the requirement document gives no sequence?

Propose an authoritative sequence, send the customer written confirmation, and record that sequence in the test report.

Can each test use a separate sample?

Yes, and sometimes necessary, to separate the effects of each agent. The downside is that cumulative effects cannot be detected — which is a real condition.

Vibration before or after damp heat?

Normally, heat is applied first to condition the joint to withstand stress, then vibrate to detect potential damage. But must follow the customer’s requirement or be agreed in advance.

Is recovery time between steps mandatory?

Many tests have provisions for conditions and recovery times before testing or moving forward. Skipping this step may cause erroneous results.

How does sequence affect lead time and cost?

High impact: changing the order can increase the number of temperature ups/downs of the chamber, increase the number of functional tests, and may force additional samples to be used.

What if results across steps are inconsistent?

Fully record the phenomenon, take photos, re-measure relevant parameters, and evaluate according to agreed criteria. An abnormal result should not be “ignored” because it will lose the value of the entire record.

9. Conclusion

In environmental testing, ordering is not an operational detail but part of the test definition. The same list of tests in different orders yields different conclusions, and this should be clearly noted in the records.

Three things to do: build chains based on usage environment, not habits; Agree functional test sequences and scores in writing before testing; and record the execution order and results of each step in the report.

How to Choose Environmental Tests from the Product’s Real Operating Environment

Rosazy

28/09/2026

Climate chamber slightly open with gray sample tray, viewed from inside the environmental testing room

The question “what does this product need to test?” is often answered by listing familiar tests. That approach easily leads to two mistakes: choosing tests that are not related to the real environment, and ignoring the most important factor.

This article shows how to choose tests according to the actual usage environment: starting with where the product will live, then moving to the IEC 60068 test list.

1. The principle: environment first, standard second

Any environmental test is only meaningful when it answers a specific question about the usage environment. So the correct procedure is:

Describe the product’s environment and journey (production, inventory, transportation, installation, use, maintenance).
Identify key actors in each stage.
Select the corresponding test group in IEC 60068.
Determine severity and duration based on environmental data.

2. Suggested test matrix by operating environment

Environment/scenario	Main stress factor	Suggested test group (IEC 60068-2)
Indoor equipment, temperate climate	Temperature and humidity depending on the season	Test A/B (cold, dry heat), Test Cab/Db (damp heat)
Outdoor, unshielded equipment	Solar radiation, rain, humidity, day-night temperature cycle	Test Sa, Test R/S/T/U, Test Cab/Db, Test N
Coastal areas, chemical factories	Salt, corrosive gas	Test Ka/Kb, Test Kc/Kd/Ke
Handheld and mobile devices	Falling, impacting, environmental temperature changes, wet hands	Test Ec, Test Ea, Test B/A, Test Db
Equipment on vehicles or construction machines	Continuous vibration, shock, mounting cavity temperature	Test Fc/Fh, Test Ea, Test A/B/N (with industry standards)
Medical equipment for home use	Room temperature, humidity, light fall, cleaning solution	Test A/B, Test XA, Test Ec (with medical industry standards)
Goods exported by sea, long-term storage	Moisture, salt, heat shock, stacking	Test Cab/Db, Test Ka/Kb, Test N (with ISTA for packaging)
Overhead equipment or air transportation	Low pressure, low temperature	Test M, Test A (with Test 2-39 when combined)
Equipment in dusty and sandy environments	Dust intrusion, abrasion	Test L (with IEC 60529 if IP class declaration is required)
Circuit boards and components in production	Welding heat, tin whisker, lead durability	Test T (Ta/Tb/Td), Test Xw1, Test U

Buồng thử nhiệt độ ẩm và thiết bị ghi dữ liệu trong phòng thử nghiệm — Hint table helps localize the test group; Severity levels must still be derived from actual environmental data.

3. The environmental profile: six inputs you need

Temperature:typical highest, lowest, and rate of change values.
Humidity:average levels and periods of high humidity with condensation.
Exposure time:total time spent under extreme conditions, in hours or cycles.
Mechanical agents:vibration, shock, and impact during transportation and work.
Chemical and biological agents:salt, industrial gases, solvents, dust.
Working status:whether the product is energized during the test, whether under load or not.

Missing any of the six items above, the test plan will have to rely on assumptions — and assumptions are the hardest part to defend in a dispute.

4. From environmental profile to severity level

What determines the level	How to interpret
Frequency of appearance	Everyday events require a different level than rare events
Duration	Same temperature but different exposure time gives different conclusions
Consequences of failure	Failures that create a safety hazard call for stricter requirements than failures that only cause inconvenience
Replacement and maintenance capabilities	Equipment that is difficult to reach requires stricter requirements
Limits of design	The level chosen should not exceed the capacity of the material if the objective is to evaluate actual use

A common mistake is to choose the highest level possible with the mindset of “the harsher the better”. This approach increases costs, lengthens time, and can misjudge the product: a device that meets the correct usage environment can still “fail” if tested at an unrealistic level.

5. Feasibility check before freezing the plan

Equipment capacity:temperature range, humidity, chamber size compared to sample size and mounting system.
Model Number:How many samples are needed for destructive testing and how many are kept for control?
Time:total chamber time, recovery time, function test time between steps.
Human resources and profile:Who monitors, who confirms the passing criteria, how is the data saved.
Conditions for receiving samples:For some tests, the sample needs to be stabilized before testing under specified conditions.

Kỹ thuật viên chuẩn bị mẫu trên bàn thử nghiệm môi trường — Checking feasibility before finalizing the plan helps avoid having to change testing mid-process.

6. Two short examples

Medical equipment for home use:The main factors are not extreme temperatures but moisture, cleaning solutions and light impact. The test plan should focus on hot humidity, seasonal room temperature, solvent testing and light roughing; The extreme temperature portion only needs to be sufficient to demonstrate the ability to withstand transportation and storage.

Electronic equipment installed outdoors along the coast:The main factors are solar radiation, diurnal heat cycles, salt and humidity. The test plan requires both Sa, N, Cab/Db and Ka/Kb; If you only test salt mist or only hot moisture, you will miss the failure mechanism due to heat cycles combined with corrosion.

7. Common mistakes

Copy another project’s test planwithout checking whether the usage environment is the same or not.
Only try agents that are easy to try(climate) and ignore difficult agents (corrosion, dust, solvents).
Do not record the power supply status of the sample,making the results unreproducible.
Skip the shipping and inventory stages,Although this is often the harshest period for electronic products.
No pre-determined criteria,leading to a favorable interpretation of the results.

Bảng điều khiển buồng khí hậu với đồ thị nhiệt độ và độ ẩm theo thời gian — The more specific the environmental profile, the easier it is to protect the chosen severity level from customers and inspection agencies.

8. Frequently asked questions

Do we need to test every test group?

No. Test only those forces that actually occur during the product life cycle, at the appropriate level. Excessive testing increases costs without increasing probative value.

What if real field data is unavailable?

Can use regional climate data, customer requirements, or recommended levels in industry standards. It is imperative to clearly state the source so readers know where that level comes from.

Should we test above the requirement “to be safe”?

Only if the objective is to evaluate the safety margin, and it must be clearly stated that the test exceeds the requirements. If this result is used to declare “satisfactory”, testing at another level may cause the dossier to not match the stated requirements.

In-vehicle equipment: IEC 60068 or automotive standards?

Usually uses industry standards for vibration, shock and temperature according to mounting location; IEC 60068 can be used for some climatic tests when referenced by an industry standard.

How do we set a sensible test duration?

Based on the actual total exposure time in the life cycle, then converted according to the principles of the standard. Do not choose a familiar number if there is no basis.

Where do we start without in-house experts?

From the table describing the usage environment and the table suggesting test groups above; Then discuss with the testing room to agree on the severity level and passing criteria.

9. Conclusion

Choosing an environmental test is a problem of properly describing the environment, not a problem of listing standards. A good test plan is one that explains: why this test exists, why that level was chosen, and why another test is not needed.

Three things to do: create a six-item environmental profile before choosing a test; choose levels according to data instead of habit; and clearly state the basis for choosing the level in the dossier so that the results can be defended when challenged.

How to Read IEC 60068 Test Designations: Ab, Bb, Nb, Db, Cab, Fc, Fh, Ea, Ka

Rosazy

28/09/2026

Close-up of the temperature test chamber control panel with round clock, digital display and mode selector switch

In IEC 60068, most of the test information is contained in a few letters. “Ab” and “Ae” are the same cold test but differ in the way the sample is brought to temperature and the way the function is tested. “Db” and “Cab” are both hot and humid tests, but one has a condensation cycle, the other does not.

This article is a decoding table of test designations, along with the most easily confused symbol pairs when writing test requests or reading reports.

1. How test designations are structured

A test in IEC 60068 is usually written in terms of four components:

Standard number:IEC 60068-2-x (x is part number).
Test names in alphabetical order:Test A, Test B, Test F…
Variant (lowercase):Ab, Ae, Bb, Bd, Na, Nb…
Severity and duration:specified by the request document.

Important points:Uppercase letters indicate groups of actors, lowercase letters indicate implementation methods. Omitting lowercase letters means losing half of the test’s information.

2. Designation decoder by test group

Group	Typical symbols	Content
Temperature	A (Ab, Ae), B (Bb, Bd), N (Na, Nb), Sa	Cold, dry heat, temperature changes, solar radiation
Humidity	Cab, Db, Cx, Cy, Z/AD, Z/ABDM	Stable humidity and heat, cycles of humidity and heat, combination cycles, and climate chains
Vibration and acceleration	Fc, Fh, Fi, Ff, Fj, Fg, Ga	Sinusoidal, random, mixed, time-history, noise-induced, steady-acceleration vibrations
Shock and rough handling	Ea, Ec, Ee, Ei, Eh	Mechanical shock, rough handling, bulk cargo, shock according to response spectrum, hammer
Corrosion	Ka, Kb, Kc, Kd, Ke	Salt mist, cyclic salt mist, SO₂, H₂S, mixed gases
Dust, water, biology	L, R/S/T/U, J	Dust and sand, water, mold
Welding and components	Ta, Tb, Td, Te/Tc, Tf, U	Weldability, solder heat resistance, solderability measurement, pin durability
Other	M, XA, Xb, Xc, Xw1	Low pressure, solvents, label abrasion, liquid contamination, tin residue

Bảng điều khiển buồng thử khí hậu với thông số nhiệt độ và độ ẩm — The test symbol determines how it is performed; The severity level is the part specified by technical requirements.

3. The designations most often confused

Pairs are easy to confuse	Core difference	Effects when used incorrectly
Ab and Ae	How to bring the sample to temperature and when to test function	The results are not comparable to customer requirements
Bb and Bd	Same as above, in hot, dry afternoon	Failure to detect errors that only appear when the sample is at high temperature
Na and Nb	Two ways to change temperature (speed and number of cycles on request)	Incorrect assessment of the thermal shock resistance of welds and materials
Cab and DB	Stable (no condensation) vs. cyclic (with condensation)	Ignore condensation failure mechanisms — a common cause of insulation leaks
Test N and heat shock according to other standards	Philosophy for choosing the level and speed of heat transfer	The conclusion is too optimistic or too pessimistic about weld durability
Ka and Kb	Continuous salt mist versus cyclic salt mist	Corrosion levels vary significantly, results are not equivalent
Fc and Fh	Sinusoidal vibration versus random vibration	Cannot reproduce actual vibration conditions (usually random)
Test K and Test C	Chemical corrosion versus hot moisture	Choosing the wrong agent does not answer the question that needs to be answered
Test U and Test Xw1	Mechanical strength of the leg compared to the tin whisker phenomenon	Ignore the risk of electric shock due to tin whiskers growing in the assembly

Mẫu thử được gá lắp trong buồng thử nhiệt độ — The same test chamber can run many different tests — distinguishing symbols helps choose the right way to sample and test.

4. Combined designations in the standard

Some parts of the standard use compound symbols to designate test series, for example Test Z/AD (combined heat-humidity cycle) or Test Z/ABDM (climate series). With these tests, the order and timing of each phase is part of the test definition, not chosen by the tester.

Additionally, some tests were withdrawn or replaced during the standard review process. When reading old documents and encountering symbols that are no longer in the current version, it is necessary to determine the corresponding replacement test before planning the test.

5. How to write designations in documents and reports

Incomplete notation	Complete notation
Test according to IEC 60068	Cold test according to IEC 60068-2-1, Ab test, level… time…
Try hot humidity	Cyclic hot humidity test according to IEC 60068-2-30 (Test Db), level… number of cycles…
Try vibrating	Wideband random vibration test according to IEC 60068-2-64 (Test Fh), level… time…
Try salt mist	Cyclic salt mist test according to IEC 60068-2-52 (Test Kb), concentration… number of cycles…

6. A four-step check of designations before testing

Compare the original request:Take verbatim customer requirements or product standards, do not use internal summaries.
Identify parts and symbols:clearly state the part number (e.g. 60068-2-30) and full symbol (Test Db).
Check severity and duration:Confirm temperature, humidity, number of cycles, exposure time, and power supply status of the sample.
Agree on achievement criteria:clearly state which test, what threshold, and who validated the results.

These four steps take a little time but help avoid trial and error — one of the most common causes of having to re-do an application.

Bản yêu cầu kỹ thuật và danh mục tiêu chuẩn trên bàn làm việc — Reviewing symbols before testing is much cheaper than retesting due to incorrect requirements.

7. Frequently asked questions

Is writing “Test A” enough?

Not enough. Test A has two variants Ab and Ae with different implementation methods; Variation and severity level should be clearly stated.

Why are there two variants of the cold test?

For different purposes: one variant is more concerned with tolerance to stable conditions, the other is more concerned with behavior when temperature changes and when testing functionality at low temperatures.

Are test designations the same across standard sets?

No. Notation is a convention specific to each set. The symbols of one set should not be used to describe tests of another set.

How do I know a test has been withdrawn?

Compare the current part lists of IEC 60068 and check the replacement notes in the standard. If old documents refer to a withdrawn test, a replacement should be agreed with the customer.

Can several designations be combined in one report?

Yes, and it is common practice when a product goes through a series of tests. It is necessary to clearly state the order, severity and pass criteria for each test.

Does a wrong designation invalidate the result?

Test results may be correct but do not prove the stated claim. In disputes, reports with incorrect symbols are often required to retry.

What if we are not sure about the designation?

Ask the party making the request in writing and ask them to clearly state the standard part number, symbol and severity level. This is a normal technical question, not a weakness of the practitioner.

8. Conclusion

The test designations in IEC 60068 contain technical information, not just reference codes. Reading the correct symbol helps businesses try it right the first time and avoid rework — a cost that is much more expensive than the time spent reading the requirements carefully.

Three things to do: always include the full designation (group + variant) in the requirements document; check the current symbol list before planning; and request the testing laboratory to record the symbol and severity level in the report.

How IEC 60068 Differs from MIL-STD-810, ISO 16750, ISTA and IEC 60529

Rosazy

28/09/2026

Three environmental testing devices sit side by side in the lab: a climatic chamber, a large vibration table, and a drop tester

“Environmental testing” is a phrase used for many different standard sets. IEC 60068, MIL-STD-810, ISO 16750, ISTA, IEC 60529 and DO-160 can all appear in the same file — but they answer different questions and apply to different subjects.

This article compares the six most frequently confused standard sets, so that companies know when each one is needed and when several must be combined.

1. Why are these standard sets so often confused?

Because they all use the same keywords: temperature, humidity, vibration, shock, dust, water. But their philosophies differ:

IEC 60068: provides methods and ranges of severity levels; the requirement writer selects the level.
MIL-STD-810: starts from real environmental conditions by operating region and platform (ground troops, vehicles, aircraft, ships) and requires life-cycle environmental analysis.
ISO 16750: specifically for electrical and electronic equipment installed on road vehicles, divided by mounting location on the vehicle.
ISTA / ASTM D4169: for transport packaging systems, not for assessing the electronic equipment itself.
IEC 60529: sets out the IP protection system and how the degree is determined, not a comprehensive climatic test method set.
DO-160 / IEC 60945: methods for the aviation and maritime industries.

2. Quick comparison table

Standard	Subject	Philosophy for choosing severity	When to use it
IEC 60068	Products, components, electrical and electronic equipment in general	The standard provides ranges; the requirement writer chooses the level	Customer requirements phrased as “to IEC 60068-2-x”; general product documentation
MIL-STD-810	Military equipment and equipment used in extreme conditions	Tied to the real life-cycle environment, with analysis	Defence projects, equipment for special environments
ISO 16750 (and ISO 19453 for electric vehicles)	Electrical and electronic equipment installed on road vehicles	By mounting location and the exposure level of the vehicle	Automotive supply chains, OEM/Tier 1 parts
ISTA / ASTM D4169	Packaging systems and shipments	By distribution mode (parcel, LTL, pallet…)	Transport testing, packaging optimisation, retailer requirements
IEC 60529	Equipment enclosures	IP protection degree determined by the specified tests	Declaring the product’s IP rating
DO-160 / IEC 60945	Aviation / maritime equipment	Environmental categories by mounting location	Products for the respective industry

Environmental testing area with several types of test equipment — The same product may have to be tested against several standard sets when different markets require it.

3. How do IEC 60068 and MIL-STD-810 differ?

The biggest difference is how severity is determined. IEC 60068 leans towards selecting from an existing range of levels, which suits situations where the requirement has already been agreed in the product documentation. MIL-STD-810 requires the real environment to be established from the life cycle and the platform of use, so the volume of input data is much larger.

For commercial companies, IEC 60068 is usually the default choice because cost and lead time are reasonable. For defence projects or equipment operating in extreme regions, only MIL-STD-810 supports the level of justification required.

4. ISO 16750: when a product goes onto a vehicle

ISO 16750 is divided by mounting location (engine compartment, passenger compartment, on the vehicle body…) and by operating state. One point companies should note: the same circuit board installed in two different locations will face different requirements. For electric and hybrid vehicles, the ISO 19453 set adds requirements for electric drive systems, while energy storage systems have their own standard set.

5. ISTA and ASTM D4169: both about transport, different subjects

IEC 60068 does include tests related to rough handling and transport (for example Test Ec, Test Ee). However, when the objective is to assess a packaging system according to distribution mode, the ISTA or ASTM D4169 set is the appropriate one, because they build a test sequence around the distribution route and evaluate the packaging together with the product inside.

In practice, a product may be tested on both tracks at once: the equipment to IEC 60068 (climate, vibration, shock) and the packaging to ISTA (drop, vibration, compression). The two sets complement each other rather than replace each other. See also our series of guides on choosing ISTA test procedures in the corresponding category.

6. Is IEC 60529 (IP rating) part of IEC 60068?

No. IEC 60529 defines the IP code system and the method for determining the degree of protection. IEC 60068-2-18 (Test R/S/T/U) provides more detailed water test methods for a different purpose. When a customer requires “IP67”, test to IEC 60529; when they require “water resistance to IEC 60068-2-18”, the scope and purpose are different.

7. When are several standard sets needed at once?

Situation	Standard sets commonly used together
Consumer electronics exported to the EU	IEC 60068 (environment) + EMC + electrical safety + chemical requirements
Automotive parts	ISO 16750/ISO 19453 + automotive EMC + material requirements
Medical equipment	IEC 60601-1 (safety) + IEC 60601-1-11 (home use) + EMC
Equipment with retail packaging	IEC 60068 (equipment) + ISTA/ASTM D4169 (packaging)
Outdoor equipment	IEC 60068 (Sa, Ka/Kb, L, R/S/T/U) + IEC 60529 + materials

Vibration test bench and measurement instruments in a reliability laboratory — Many standard sets share the same equipment but differ in how severity levels and acceptance criteria are chosen.

8. Common mistakes when citing standards

Mixing criteria: taking MIL-STD-810 severity levels but applying IEC 60068 acceptance criteria.
Wrong inference: treating “passes IEC 60068” as sufficient to conclude that the equipment withstands the automotive environment.
No mounting location analysis: applying one level to every mounting location on a vehicle.
Ignoring the subject: using a packaging test to draw conclusions about the equipment, or the reverse.
Not checking the edition: the product standard refers to an old edition while the documentation cites a newer one.

Technical requirement documents and standards records on a desk — When a product must satisfy several markets, stating the standard set and edition applied for each market is how duplicate testing is avoided.

One further practical note: industry standard sets often refer back to IEC 60068 for certain tests (climate testing, for example), while setting their own rules for choosing vibration or shock levels. So reading the industry standard first, and only then the method set, will make a test plan leaner and more accurate.

9. Frequently asked questions

If the customer does not specify a set, which should we use?

Ask again in writing. IEC 60068 is the default for general electrical and electronic products, but confirm it, because this directly affects cost and whether the result will be accepted.

Does IEC 60068 replace ISO 16750 for automotive parts?

No. The two differ in how severity is determined and in their context of application.

If we have already done ISTA, do we still need IEC 60068?

Yes, if the objective is to demonstrate the equipment’s resistance to climatic conditions. ISTA focuses on the packaging system and the distribution journey.

Can an IP rating replace water testing to IEC 60068?

No. The IP rating is a classification of protection with its own method; water testing to IEC 60068-2-18 serves a different purpose and severity.

Is there a “parent” standard set that covers everything?

No. Each set serves a subject and a context; the choice is based on market and customer requirements.

What should be recorded in technical documentation to avoid confusion?

Three elements: the standard number with year, the test code and severity level, and the acceptance criteria. These three resolve almost every dispute about “which standard was tested”.

10. Conclusion

IEC 60068, MIL-STD-810, ISO 16750, ISTA, IEC 60529 and DO-160 do not compete with each other — they serve different objectives. The most common error is not choosing the wrong standard, but citing a standard without stating the part, the level and the acceptance criteria.

Three things to do: confirm the standard set and edition with the customer in writing; clearly separate equipment testing from packaging testing in the test plan; and record enough information for a third party to verify the result.

TCVN 7699 and IEC 60068: Vietnam’s Equivalent Standard Set, and When to Use Which

Rosazy

28/09/2026

Desk in the test room with plain folders and stacks of blank documents next to the temperature chamber

In technical documentation in Vietnam, the same cold test may be recorded as “TCVN 7699-2-1” or as “IEC 60068-2-1”. These are not two different standards, but they are also not entirely identical once you compare the editions.

This article explains the relationship between the TCVN 7699 set and the IEC 60068 set, when to cite which one, and the points to check before signing off on a test result.

1. TCVN 7699 is the Vietnamese edition of IEC 60068

TCVN 7699 is Vietnam’s national standard set for environmental testing, built by adopting the IEC 60068 set. For example, TCVN 7699-1:2007 corresponds to IEC 60068-1:1988 plus Amendment 1:1992. The 2-x parts of TCVN 7699 correspond to the 2-x parts of IEC 60068 (cold, dry heat, vibration, salt mist, damp heat, and so on).

So when you read a report stating TCVN 7699-2-1, you can understand it as a cold test following the method of IEC 60068-2-1 — but you must establish which edition was adopted, because that is the single most important difference.

2. Why are there two ways of citing the standard?

Context	Usual citation	Reason
Legal documentation, declarations of conformity in Vietnam	TCVN / QCVN	The national standards system is the basis cited in domestic documentation
Contracts with overseas customers	IEC 60068-2-x	Customers use the international IEC system, usually quoting the edition year
Certification requirements under a product standard	Either or both	The product standard refers to the corresponding test method set

A point to note: the TCVN edition adopts one specific IEC edition at the time of review. If IEC has since published a newer edition, the technical content may have changed in some details (temperature ranges, functional checks, recovery times).

Standards documents and test records on a laboratory desk — Citing the standard by its correct name is not enough — you also need the right part, test code and edition year.

3. Three questions to answer before testing

Which set applies? TCVN 7699 or IEC 60068 — decided by the applicable documentation, not by the habit of the laboratory.
Which edition? If the contract specifies IEC 60068-2-2:2007 but the laboratory applies the older TCVN equivalent, this must be recorded and agreed in writing.
Which severity and duration? Both sets leave the level for the requirement writer to choose. A report without a level is a report that cannot be defended.

4. Differences that can lead to disputes

Edition mismatch: the method content of the adopted edition and the current IEC edition may differ in technical detail.
Different interpretation of acceptance criteria: the same test with different functional criteria and check points leads to different conclusions.
Missing supporting documentation: chamber performance confirmation and measurement uncertainty are the parts most often omitted from the file.
Vague reporting: “passes TCVN 7699” says nothing about which test or which level — write it in detail, such as “test Ab to TCVN 7699-2-1, temperature… duration…”.

5. How to cite the standard correctly

Element to record	Example
Standard number with year	TCVN 7699-2-1:2007 or IEC 60068-2-1:2007
Test code	Ab / Ae / Bb / Bd / Nb / Db / Cab…
Severity level	Temperature, humidity, duration, number of cycles
Specimen state during test	Not energised / energised, measured during or after the test
Acceptance criteria	Which functional and mechanical checks, at which thresholds
Supporting documentation	Method used to confirm chamber performance

Temperature sensors and data logger inside a test chamber — Test condition data attached to the report is the evidence that the test took place as described.

6. How this affects the value of your documentation

If you export, customers will usually compare your report against the list of tests in their requirement documents. A report that states the correct test code and severity level is accepted quickly; a vague report usually triggers a request to redo the work — and the resulting cost is far higher than writing it precisely from the start.

Conversely, for domestic documentation, citing TCVN 7699 with the right part makes the file easier to accept. Where goods fall under quality management requirements, you should also check the requirements in the Ministry of Science and Technology’s list of risky goods and the corresponding technical regulations.

7. Quick cross-reference of commonly used parts

TCVN (national set)	Corresponding IEC	Content
TCVN 7699-1:2007	IEC 60068-1:1988 and Amendment 1:1992	General provisions and guidance
TCVN 7699-2-x	IEC 60068-2-x	The tests: cold, dry heat, vibration, damp heat, salt mist, soldering…
Part 3-x of the national set (where available)	IEC 60068-3-x	Supporting documentation: chamber confirmation, test selection, uncertainty

When working on domestic documentation, look up the specific TCVN edition currently in force rather than inferring part numbers from the IEC edition. Conversely, when working with international customers, cite the IEC number so that the recipient does not have to look up the equivalent themselves.

Temperature test chamber with records of test conditions — Recording the correct standard number and edition year lets the test result be verified across repeated inspections.

8. Frequently asked questions

Are TCVN 7699 and IEC 60068 the same thing?

TCVN 7699 was built by adopting IEC 60068, so the methods are equivalent, but the numbers and edition years differ.

A customer requires IEC. Can I test to TCVN instead?

Only with the customer’s written agreement. The safest approach is to issue the report under the standard number the customer requested, with a note about the equivalent edition where applicable.

Must everything be redone if there is a minor edition mismatch?

Not every difference invalidates the result. Compare the original texts of both editions on the clauses dealing with severity level and functional checks, then assess the impact.

Can I write “equivalent to IEC” in the report?

Write it out precisely: “performed to TCVN …, equivalent to IEC … edition of …” so the reader can verify it, rather than a bare word “equivalent”.

Are national standards mandatory?

National standards are generally voluntary; they become mandatory when cited in a legal instrument, a contract or a declaration file. This must be checked case by case.

What should a laboratory record in the report to avoid disputes?

At minimum: standard number and year, test code, severity level, test condition data, how the specimen was mounted, the acceptance criteria and the result against each criterion.

What if the applicable TCVN edition is older than the latest IEC edition?

Compare the relevant clauses of both editions and state in the report which edition was applied. If the difference affects the conclusion, agree with the customer on additional testing to the newer edition.

May I translate a standard for internal use?

A translation for internal reference does not replace the original text of the standard. When a citation is needed in documentation, you must refer to the official standard number and a valid published edition.

9. Conclusion

TCVN 7699 and IEC 60068 are two ways of citing the same system of methods. The issue is not which name you pick, but whether you record enough information for the result to be verified: which part, which test code, which edition, which severity level, which acceptance criteria.

Three things to do: agree in writing with the customer on the standard set and edition applied; record details in the report instead of a general citation; and keep the test condition data together with the equipment performance confirmation file.

Rosazy

28/09/2026

Documents and desks represent Circular 36/2026/TT-BKHCN on the list of risky goods

On June 30, 2026, the Ministry of Science and Technology issued Circular 36/2026/TT-BKHCN regulating the List of products and goods with medium-risk and high-risk levels under the management responsibility of the Ministry of Science and Technology. The Circular takes effect from July 1, 2026 and replaces a series of previous documents on the list of group 2 goods in the fields of standards – measurement – quality and information technology – telecommunications.

Reference translation by ticforall.com. The Vietnamese version published on this site is the authoritative text; in case of any discrepancy, the Vietnamese original prevails.

This is a document that directly affects the production, import and circulation of many product groups: petroleum and fuel, cables and electrical equipment, iron and steel, household electrical and electronic equipment, telecommunications equipment, information technology equipment, radiation and nuclear equipment. Below is the full text of the circular (8 articles), verbatim Appendix I (list of high-risk goods) and Appendix II (list of medium-risk goods) with full HS codes, technical regulations, product descriptions and corresponding quality management requirements, along with a comment on the impact on businesses.

1. Main points of Circular 36/2026/TT-BKHCN

Changing the way of classifying goods:Instead of the concept of “group 2 products and goods” (likely to cause unsafety), the circular divides it into two levels:high level of risk(Appendix I) andaverage level of risk(Appendix II). Each line of goods is assigned an HS code, applicable technical regulations, product description and corresponding quality management requirements.
High-risk goods:To certify conformity, test results must come from a recognized testing organization, designated or recognized by the Ministry of Science and Technology, with a testing scope in accordance with the corresponding national technical regulations (Article 3, Clause 3).
Medium risk goods:Test results used for self-assessment or certification of conformity must also be by a recognized, designated or recognized testing organization (Article 4, clause 3).
One commodity, many standards:If the product simultaneously falls under two or more national technical regulations, it must fully meet those regulations, but do not duplicate assessment content for the same evaluated technical requirement (Article 5, Clause 2).
Assignment to inspect imported goods:The specialized science and technology agency under the Provincial People’s Committee organizes state inspection of the quality of imported goods with high levels of risk, except gasoline, diesel fuel, biofuel and liquefied petroleum gas (LPG) (Article 8, clause 4).
Forward:Certificates of conformity and notices of receipt of declarations of conformity issued before the effective date of the Circular will continue to be used until the expiration date stated in the document (Article 7, Clause 1).

2. Comment: how does this change impact the business?

The following is ticforall.com’s assessment based on the circular content and referenced documents; This is not a legal conclusion for a specific shipment.

2.1. From “group 2” to “risk level” — change in the nature of the procedure

Previously, goods in the category 2 list were often processed towards certification of conformity and declaration of conformity with relatively flexible timelines between industries. Separating into two risk levels entails two different paths: the high-risk group is associated with certification of conformity by the designated certification organization, while the medium-risk group can follow the direction of self-assessment on the basis of test results. For import businesses, correctly determining whether an item is in Appendix I or Appendix II is the most important step, because it determines the entire dossier and progress behind it.

2.2. Time to complete certification of conformity

The Circular stipulates that state inspection of the quality of imported goods is carried out in accordance with the provisions of law on product and goods quality and references Decree No. 37/2026/ND-CP. Enterprises need to compare the verbatim of this decree to determine the specific time and sequence for each high-risk shipment, instead of assuming that in all cases a certificate can be added after the goods have arrived in the warehouse. Article 7, Clause 4 of the circular also notes the registration for state inspection during the period when the National Single Window Information Portal is adjusted and upgraded.

For shipments that have pre-existing test results or certificates, Article 7 is the part that needs to be read carefully: dossiers received before July 1, 2026 but not yet resolved will continue to be implemented according to the regulations at the time of receipt.

2.3. Cost and time: additional expenses need to be calculated in advance

Tested according to standards:High-risk goods must have test results from a recognized or designated testing organization, whose scope is consistent with the respective national technical regulations. If the product belongs to multiple standards, the number of criteria and samples to be tested will increase accordingly.
Certificate of conformity:For high-risk groups, businesses need to work with a designated certification organization — cost and time depend on the conformity assessment method applied.
Storage and storage costs:If the goods are not eligible for customs clearance at the time of inspection, the costs incurred are often in storage and adjusting delivery plans, not just in testing fees.
Time to prepare documents:Gathering product descriptions, HS codes, applicable standards and testing results often takes more time than businesses expect, especially for products with many variations or models.
Risk of goods being detained at the border gate:With high-risk goods, discrepancies in paperwork at the time of inspection can disrupt the delivery schedule to customers.

The level of impact is not the same between industries: petroleum, iron and steel, telecommunications equipment – information technology and radiation equipment have a very detailed list according to HS codes, in which many lines differ only in configuration or operating frequency range. Comparing the correct flow of goods is a decisive factor in cost estimation.

Enterprises should also clearly distinguish test report, certificate of conformity and declaration of conformity — three types of documents that are different in nature and use value. On the laboratory side, accredited competence according to ISO/IEC 17025 and specified scope are necessary conditions for acceptable test results.

Most of the quality management requirements in the two appendices refer to the conformity assessment method according to Circular 14/2026/TT-BKHCN. Enterprises should determine in advance which method their products fall into (sample evaluation, production process evaluation or combination) to prepare corresponding documents.

2.4. Six documents are no longer valid – need to review the current list

Circular 29/2025/TT-BKHCN dated November 13, 2025 (list of products and goods that can potentially cause insecurity in the information technology and telecommunications sector).
Circular 30/2011/TT-BTTTT dated October 31, 2011 on certification of conformity and declaration of conformity for products specialized in information technology and communications.
Circular 15/2018/TT-BTTTT dated November 15, 2018 amending and supplementing Circular 30/2011/TT-BTTTT.
Circular 10/2020/TT-BTTTT dated May 7, 2020 amending and supplementing Circular 30/2011/TT-BTTTT.
Joint Circular 58/2015/TTLT-BCT-BKHCN dated December 31, 2015 on quality management of domestically produced and imported steel.
Circular 01/2009/TT-BKHCN dated March 20, 2009 on the list of potentially unsafe products and goods under the management responsibility of the Ministry of Science and Technology.

The point to note is that the national technical regulations referenced in the list (eg QCVN on petroleum, electric cables, telecommunications equipment, radiation equipment) continue to be in effect; This circular replaces the list and quality management requirements, but does not abolish the corresponding standards.

2.5. Checklist of 7 things businesses should do immediately

Review all HS codes being imported/produced, compare with Appendix I and Appendix II of Circular 36/2026/TT-BKHCN to determine the level of risk.
For each product line, clearly state the applicable national technical regulations and the criteria that must be tested.
Check the capacity and accredited/designated scope of the testing laboratory being used compared to the corresponding QCVN.
Plan for certification of conformity or declaration of conformity according to the appropriate conformity assessment method for each product.
Review existing certificates and notices of receipt of declaration of conformity to take advantage of the transitional provisions in Article 7.
Update the import process: documents, time to register for state inspection and focal points to work with provincial inspection agencies.
Follow the National Single Window Information Portal/National Public Service Portal and guidance from the Ministry of Science and Technology during the transition period.

What is IEC 60068? Structure of the Environmental Testing Standard Set and How to Read Test Codes

Rosazy

28/09/2026

Environmental test chamber with climatic chamber, electrodynamic vibration table and salt mist chamber lined up — cover image of what IEC 60068 is

IEC 60068 is the international standard set for environmental testing of electrical and electronic products. When a technical requirement says “tested to IEC 60068-2-1” or “tested to IEC 60068-2-30”, the reader needs to know immediately what that test is, how severe it is, and who has the authority to decide the severity level.

This article explains the three document groups that make up the standard set, how to read test code letters, and the points most often misread when IEC 60068 is quoted in technical documentation.

1. What is IEC 60068 and which products does it cover?

IEC 60068 is a collection of environmental test methods used to assess how products behave under conditions such as cold, dry heat, damp heat, vibration, shock, corrosion, dust, water and low air pressure. The standard set addresses electrical and electronic products, components, assemblies and complete equipment.

The key point to understand: IEC 60068 provides methods and ranges of severity levels; it does not prescribe which level a given product must withstand. Selecting the test and the severity level belongs to whoever writes the requirement — the customer, the manufacturer, or an industry standard. That is why a test report stating only “passed IEC 60068” without naming the part, the level and the duration cannot be verified against anything.

2. The three document groups

Group	Function	Examples
IEC 60068-1	General provisions and guidance: terminology, standard atmospheric conditions, principles for choosing severity levels	Measurement and test conditions, how to report results
IEC 60068-2-xx	The individual tests; each part corresponds to one agent or one family of agents	60068-2-1 (cold), 60068-2-6 (sinusoidal vibration), 60068-2-11 (salt mist)
IEC 60068-3-x, 60068-4, 60068-5-2	Supporting documents: technical guidance, chamber performance confirmation, how to choose between tests, terminology	60068-3-5 and 3-6 (chamber confirmation), 3-8 (selecting vibration tests)

These three groups play different roles. Part 2 is what you use to run a test; Part 3 is what you use to run the test correctly — making sure the chamber, the measurement chain and the mounting do not introduce errors of their own.

3. Classifying tests by agent family

Agent family	Typical tests	Question the test answers
Temperature	Test A (cold), Test B (dry heat), Test N (change of temperature)	Does the product still work and remain intact when temperature changes or reaches extremes?
Humidity	Test Cab, Test Db, Test Z/AD, Test Cx, Cy	Do humidity and condensation degrade insulation, cause corrosion or functional faults?
Mechanical	Test Fc, Fh, Fi, Ff/Fj, Ea, Ei, Ga, Eh	Do vibration and shock cause cracks, loosened joints, structural failure or intermittent faults?
Transport and handling	Test Ec, Ee	Does the product survive drops, toppling, edge impacts and loose cargo during transport?
Corrosion and chemical environment	Test Ka, Kb, Kc, Kd, Ke	How do salt-laden or industrial atmospheres affect contacts and coatings?
Dust, water, biological	Test L, Test R/S/T/U, Test J	Can foreign objects and biological humidity penetrate and damage the equipment?
Soldering and components	Test T (Ta/Tb/Td), Test Te/Tc, Test U, Test Xw1	Do components withstand soldering heat, lead robustness and whisker growth?
Others	Test M (low air pressure), Test Sa (solar radiation), Test XA/Xb/Xc	Application-specific conditions: altitude, outdoor exposure, solvents, marking abrasion

Climate test chamber in an environmental testing laboratory — Most IEC 60068 climate tests are performed in a temperature and humidity chamber with controlled conditions.

4. How to read a test code

Test names in IEC 60068-2 normally carry two layers of code: a capital letter (A, B, C, E, F, J, K, L, M, N, Q, R, S, T, U, X) and a second, lower-case letter indicating the variant (for example Ab and Ae, Bb and Bd, Na and Nb).

Common codes	Family	What to remember
Ab, Ae	Test A — Cold	Two variants differing in how the specimen reaches temperature and when functionality is checked
Bb, Bd	Test B — Dry heat	The same logic with the temperature direction reversed
Cab	Test C — Damp heat, steady state	One constant temperature and humidity condition held throughout the test
Db	Test D — Damp heat, cyclic	Repeating cycles that include a condensation phase
Fc, Fh, Fi	Test F — Vibration	Sinusoidal, broad-band random, mixed mode
Ea, Ec, Ee	Test E — Shock and rough handling	Mechanical shock, rough handling, loose cargo
Ka, Kb, Kc, Kd, Ke	Test K — Corrosion	Salt mist, cyclic salt mist, SO₂, H₂S, mixed gas
Ta, Tb, Td, Te/Tc, Tf	Test T — Soldering	The family of tests related to soldering processes
Xb, Xc, Xw1	Test X — Miscellaneous	Marking abrasion, contamination by fluids, solder whiskers

Measurement instruments and sensor system used in environmental testing — A test code only identifies the agent; severity, duration and measurement method come from the requirement document.

5. Where misreadings usually happen

Assuming the standard chooses the level. The standard offers a range of options; the requirement writer must select and state one.
Confusing the test with the condition. The same test name at different temperatures, humidity levels or durations leads to entirely different conclusions.
Ignoring the supporting documents. If the chamber performance has never been confirmed, the result is hard to defend in a dispute.
Not recording how the specimen was mounted. In vibration and shock testing, mounting can change the resonant frequency and the amplitude actually seen by the specimen.
Not defining acceptance criteria. Decide in advance which failures are critical, which are acceptable, and at which points functionality is checked.
Using test results to infer service life. Environmental testing to IEC 60068 answers “does it survive this condition”; it does not automatically yield a lifetime in years.

6. Who benefits from this standard set?

Equipment manufacturers: they need evidence of environmental robustness before selling or before entering a supply chain.
Importers: they need to match customer or certification requirements against the methods actually available in a laboratory.
Design teams: they use the results to find design weaknesses, not merely to obtain a certificate.
Testing bodies: they need the right test, the right level, the right acceptance criteria and a traceable record.

Vibration test bench and measurement equipment in a reliability laboratory — After testing, the record is only useful when the result is tied to the correct standard part, test code and applied severity level.

A practical observation: many companies send samples for testing but keep no record of the test conditions (temperature and humidity over time, mounting arrangement, agreed acceptance criteria). When a customer or an inspector asks for justification, the absence of that data erases the value of an otherwise correctly performed test.

7. Frequently asked questions

Can IEC 60068 replace MIL-STD-810?

No. They are two different method systems with different philosophies for choosing severity and different target products. Which one applies depends on customer requirements, market and industry sector.

What does it mean for a product to “pass IEC 60068”?

By itself, nothing definite. You must state the part (for example 60068-2-1), the test code (Ab or Ae), the temperature, the duration and the acceptance criteria.

Must testing be done in an accredited laboratory?

Not in every case. But when a third party has to accept the result, laboratory competence and the accredited scope are decisive for how much the result is worth.

How many samples are enough for an environmental test?

There is no universal number. Sample size depends on the objective (qualitative assessment or trend monitoring), the value of the samples, and the acceptance criteria agreed in advance.

Can a slower, cheaper test be substituted?

Only when the requirement document allows it. Substituting a test without documenting the change is a common root cause of disputes when goods are returned.

Which document should a newcomer read first?

Start with IEC 60068-1 for terminology and principles, then move to the Part 3 guidance that corresponds to the test you are about to perform.

8. Conclusion

IEC 60068 is a set of methods, not a set of prescribed levels. Understanding the three document groups and how test codes are read helps companies avoid quoting a standard by its correct name while misstating what it actually requires.

Three things to do immediately: record the full standard part and test code in technical documentation; define acceptance criteria before testing; and confirm chamber performance before issuing conclusions that may be challenged.
