Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Introduction
This document describes:
— A range of garment tests to be carried out on general, industrial or Emergency Team (ET) chemical
protective clothing
— Practical performance tests (mandatory and optional)
— Performance classifications or pass/fail criteria
— Where not described elsewhere, reporting requirements.
This document is part of a series of standards for test methods and requirements for both limited use
and reusable chemical protective clothing. ISO 16602 consists of the following parts, under the general
title "Protective clothing for protection against chemicals — Classification, labelling and performance
requirements":
— Part 1: General requirements;
— Part 2: Physical test methods, classification and requirements;
— Part 3: Chemical test methods, classification and requirements;
— Part 4: Test methods, classification and requirements for specific designs and ensemble components
including gloves, footwear, and respirators;
— Part 5: Garment test methods, classification and requirements;
— Part 6: Guidance on Selection, Use, Care and Maintenance.
This document, regarding the garment tests, is based on the existing test methods found in ISO 16602,
ISO 17723-1, ISO 17491 series, in EN 1073 series or practical performance tests in other product standards.
This series of documents is intended to provide a new modular approach design and specification for
chemical protective clothing accommodating the many types and levels of risk found, and activities carried
out, in the workplace. This document includes the requirements of ISO 8194 on Radiation protection so that
it can be withdrawn.
The selection of appropriate chemical protective clothing should be based on a risk assessment. In this
assessment the user organization identifies the hazards, and determines
— the potential for chemical contact with individual workers,
— the consequences of exposure, and
— the type of practices or controls needed to eliminate or minimize exposure.
When it is determined that chemical protective clothing is needed, the risk assessment should identify
the chemical protective clothing required in terms of its overall performance requirements from physical
characteristics, chemical protection and garment test perspective. ISO/DIS 16602-6 is intended to assist
user organizations with these determinations.

4 Pre-treatment
4.1 Pre-treatment by cleaning and disinfection
Prior to testing, specimens shall undergo pre-treatment according to ISO/DIS 16602-1:— (4.3.1).
4.2 Testing temperature
Specimens shall be conditioned and tested according to the requirements defined in ISO/DIS 16602-1:—
(4.3.2 and 4.3.3).
4.3 Optional extreme storage conditions
If claimed in the manufacturer’s instructions (IFU) (ISO/DIS 16602-1:— (11.1b)), conditioning at extreme
storage conditions shall be applied according to ISO/DIS 16602-1:— (4.3.4).
5 Practical performance
5.1 General
Different practical performance tests are appropriate for different tasks and PPE.
Conditioning by wearing is required for all chemical protective clothing, including partial body, undergoing
any garment test in this document. The purpose of the practical performance test is to evaluate:
— Any inhibition of the wearer’s movement,

ISO/DIS 16602-5:2025(en)
— Wearer discomfort,
— The interferences between separate items comprising an ensemble,
— The potential for loss of integrity, and
— Manufacturers’ sizing charts.
prior to one of more of the garment tests described in this document.
Some of the practical performance tests are required for all garment tests, such as those described in 5.2 and
5.3. Others shall only be used when applicable, for example in the case of integral glove (5.7) or visors (5.8).
Some tests are optional such as in 5.4, 5.5, 5.7 or 5.9 depending on intended use. The number of samples and
number of different test subjects needed to carry out are specified in the garment test in clause 6 or specified
in the optional tests. The optional tests are not intended to be carried out prior to all garment tests.
The test subject shall be dressed according to both the garment test and following the directions in the
manufacturer's instructions. Subjects shall also don any other items of protection specified in the
manufacturer’s instructions. If the manufacturer's instructions do not require or indicate that any interfaces
between different components of an ensemble should be taped (such as at wrists and ankles) then tape shall
not be applied.
These tests shall be carried out also for partial body protection garments, taking into account the design and
area of intended protection. For example, the size of the partial body protection garment shall not create any
hindrance as used by the test subject. This shall be checked by visual inspection (e.g. an apron being so long
that it would create a tripping hazard).
All chemical protective clothing shall be conditioned as follows, unless indicated differently in this document:
— For single or limited use: take out of packaging and wrapping, and proceed with the test.
— For reusables: test according to the two following conditions:
— take out of packaging and wrapping and proceed with the test (no pre-conditioning if stored in
ambient temperatures), and
— pre-condition according to 4.1 and 4.2 based on the manufacturer’s instructions and then proceed
with testing.
NOTE These practical performance test can also be performed by users to assess the protective clothing and its
fitness for purpose.
5.2 “Fit” practical performance test
5.2.1 General
The purpose of this subjective test is to assess whether the sizing information for the garment matches an
informed wearer’s expectation.
The test shall be carried out by a number of test subjects and for the number of samples indicated in clause 6.
The test temperature and humidity shall be recorded. The test subjects shall be familiar with using such
or similar protective clothing. The persons will be drawn from those people certified as fit to do so by an
appropriate medical officer according to local regulations. The necessity of a medical examination before or
supervision during the tests shall be at the testing officer's discretion. Two suits shall be tested, each being
tested on a different test person. Carry out the movements, 3, 6 and 7 of Annex A.
Prior to the test, there shall be an examination that the suit is in working condition and that it can be used
without danger.
If more than one size of a given item of clothing is manufactured, the subjects are asked to select the
appropriate size, depending on what is worn underneath the test garment. A minimum of two sizes shall be
tested with two test subjects fitted for the different sizes.

ISO/DIS 16602-5:2025(en)
After donning the suit, each test subject is asked "Does the suit fit?" If the answer is "Yes" the subject shall
proceed with the test in 5.3.
If the answer is "No", report the fact and either replace the suit or the test subject. The test subject is
then asked again "Does the suit fit?" If the answer is “Yes”, the subject shall proceed with the remaining
movements in 5.3. If the answer is “No”, or if the suit does not fit any test subject within the given size range,
the sizing table shall be reported as incorrect and the suit test shall be reported as a failure. This shall also
mean that the garment fails the requirements of ISO/DIS 16602-1.
The following are examples of obvious reasons for concluding that a protective clothing product is
unacceptable and not fit for use:
1) The selected garment size based on the subject's size does not fit in a way to provide safe use due to
sizing or design;
2) It does not stay closed or it will not stay in place;
3) It compromises a vital function such as breathing;
4) Simple tasks to be performed wearing it are impossible. For example:
— Reading off a measuring device (e.g. an electronic device with a display);
— Securing and using fastenings and couplings;
— Accessing controls, warning devices and pressure gauge (if fitted);
5) The subject refuses to continue this assessment due to pain;
6) It prevents the wearing of other essential PPE.
The result shall be reported along with:
— the size dimensions of the test person including any undergarments worn underneath the test garment;
— any observations such as ease of donning and doffing the garment according to IFU.
5.2.2 Garment size determination
The test subject shall be dressed in the absorbent overall or other undergarment for the garment test (for
example for 6.4 Liquid performance tests), in accordance with the IFU (ISO/DIS 16602-1:—, 11.1b), as well as
any other items of protection.
NOTE 1 When using for example an absorbent overall, the sizing of this overall should not inhibit the practical
performance test.
The body dimensions of the test subject, in particular the chest measurements, shall be measured including
all garments underneath the test garment (e.g. underwear, undergarments, any garment worn to protect the
test subject, absorbent overall). The test garment size shall be based on the range indicated on the size label
of the suit to be tested using the above measurements.
NOTE 2 Garment fit: Although the test subjects should be selected as close as possible to the upper limit of the
size range, the garment should not be too tight before the practical performance test as this may stretch the seams.
If garments are too big, leakages may not be detected because there is no contact between the test garment and the
absorbent overall. Overall, a garment that is too tight is worse than one that is slightly too loose. Contact between the
absorbent overall and the inside of the garment are important for the garment test. Care should be taken to ensure
that garment size selection for both the absorbent overall and the test garment can achieve contact given the test
subject’s body dimensions.
ISO/DIS 16602-5:2025(en)
5.3 “Seven Movements” practical performance test
The purpose of this test is to show that the garment allows the wearer to perform a range of basic movements
without either inhibiting those movements or causing the suit to potentially fail to protect. The tests shall
be carried out by the number of test subjects and for the number of different samples indicated in clause 6.
The test shall be carried out according to Annex A.
The garment shall be deemed to have passed the “Seven Movements” test, unless either:
— any test subject is not able to perform one or several movements due to the hindrance of the suit, or
— the movements result in substantial damage to the suit, or
— any part of the body becomes uncovered in any of the 7 movements.
In any of these cases, the garment shall be disqualified from further testing.
Once a garment has passed this test, carry out other optional practical performance tests. Subsequently at
least one of the garment tests in clause 6 or subsequent clauses shall be carried out. Report the result and
any observations.
5.4 “Mobility” practical performance test
This test is mandatory for any garments for Emergency Teams (ET) in 6 (of any design) and mandatory for
any other kind of garments depending on intended uses.
The purpose of this test is to show that the garment allows the wearer to move around the workplace
without either inhibiting those movements or causing the suit to potentially fail to protect. The tests shall be
carried out on two samples by two test subjects (preferably two different ones).
During this test the following activities shall be carried out in simulation of the practical use of the suit.
a) Walking on the level with full headroom at a regular rate of (5 ± 0,5) km/h for 5 min;
b) Walking on the level with restricted headroom due to a ceiling height of (1,3 ± 0,2) m for a total distance
of 50 m;
c) Climbing up and down a ladder with an inclination of (85 ± 5)° from horizontal and a total vertical
distance of 6 m for 5 min (min. of 4 times up and down).
Report if the test was completed and at least any of the below observations:
— The following observations would be considered failures:
— One or more wearers could not complete all the tasks;
— The garment or other PPE created a hazard;
— One or more wearers experienced significant discomfort;
— Execution of one or more of the exercises resulted in damage to one or more of the garments;
— One or more garments failed to cover areas of the body intended to be protected (e.g. zip comes open);
— One or more garments temporarily failed to cover areas of the body intended to be protected (e.g.
forearm is exposed when the wearer stretches up, but covered again with arms by sides).
— Any other informative (non-normative) comments from the test subject.

ISO/DIS 16602-5:2025(en)
5.5 “Workplace Activity” practical performance test
5.5.1 General
This test is mandatory for any garments for Emergency Teams (ET) in 6 (of any design) and in sub-
clauses 5.5.2, 5.5.4 and 5.5.5 and mandatory for any other kind of garments depending on intended uses.
The purpose of these tests is to show that the garment allows the wearer to carry out a range of practical
tasks. The tests shall be carried out on two samples by two test subjects (preferably two different ones),
in addition to any other required PPE for the task (e.g. face mask, RPD). Any of the following tasks in sub-
clauses 5.5.2 to 5.5.7 can be carried out. The report shall indicate which parts were performed and at least
any of the following observations:
— The following observations would be considered failures:
— One or more wearers could not complete a task or report severe restrictions to movement;
— Damage to one or more garments;
— Failure of one or more garments to cover areas of the body intended to be protected (e.g. zip comes open);
— The flow rate and distribution of air into the garments caused distress to the wearer;
— Any other informative (non-normative) comments from the test subject.
5.5.2 Laying out a firehose
Laying out a flat fire hose 15 m (+5/-1 m) in length and recoiling the same. This is to be carried out once.
5.5.3 Shovelling polystyrene chips from a bunker into a basket
Filling a small basket (see Figure 1, approximate volume 8 L) with 12 mm chippings (e.g. limestone chippings)
or other suitable material from a hopper which stands 1,5 m high and has an opening at the bottom to allow
the contents to be shovelled out and a further opening at the top where the chippings may be returned. The
test subject stoops or kneels and fills the basket with chippings. They then lift the basket and empties the
contents back into the hopper. This shall be repeated 15 to 20 times in 10 min.
Figure 1 — Hopper and basket
ISO/DIS 16602-5:2025(en)
5.5.4 Cordoning-off an area
Simulate cordoning off an area of 10 m x 20 m with a single rope (nominal length of 65 m and a nominal
diameter of 1 cm), using 12 displaceable posts, one for every 5 m, clipping the single rope on each post.
NOTE This can be done either in a big room or outside. If the room is small, it can be done by several rounds
cordoning off a smaller area
5.5.5 Crawl
Crawling on a smooth surface on the level with a ceiling height of 0,70 (+0,05/-0) m for a total distance of
10 m. If a suit passes on a slightly lower ceiling, then it shall be deemed to have passed;
The surface shall be no smoother than a seamless Class 41 resilient floor covering according to

1) ISO 16905 or EN 1817(for smooth homogeneous rubber), or
2) ISO 10582 or EN 651 (for PVC with a foam layer), or
3) ISO 26986 (for expanded PVC floor coverings) and be laid according to the flooring manufacturer’s
instructions.
If a suit passes on a rougher flooring surface, then it shall be deemed to have passed on a floor as specified
above. If a suit doesn't pass on a rougher surface then the test shall be repeated on a floor as specified above.
5.5.6 Hearing and speech
Protective clothing that are fully encapsulated, including potentially RPD, when tested, shall meet the
communication performance requirements.
Two test subjects shall wear the same PPE clothing, stand at a distance of (2 ± 0,5) m apart in an
environmental background level of 65 dBA to 70 dBA of pink noise. The test officer shall write down the
numbers “1” to “20” in random order and pass the list to the first test subject. The first test subject shall call
out the numbers in the given order. A second test subject shall be able to understand the numbers called out
by the first test subject and write them down.
At least 15 numbers out of 20 shall be written down correctly.
5.6 “Low temperature activity” practical performance test (optional)
The purpose of this test is to show that the garment allows the wearer to carry out a range of exercises in a
low-temperature environment (see ISO/DIS 16602-1:—, 4.3.4).
The requirements of conditioning and minimum practical performance tests shall be carried out according
to clause 6 (including the number of samples and number of persons needed). The test shall be carried out
on two samples by two test subjects (preferably two different ones), in addition to any other required PPE
for the task (e.g. face mask, RPD).
All tests shall be carried out in a cold chamber at (-15 ± 3) °C. The test temperature shall be recorded. Work
simulation tests at low temperature shall be carried out within a period of between 15 min and 45 min. The
following activities shall be carried out:
a) Walking on the level at a regular rate of 5 km/h for 5 min;
b) Crawling on a surface on the level keeping all of the ensemble below a height of (0,70 + 0,05/-0) m for a
total distance of 10 m. The surface shall be as specified in 5.5.6.
This is only required when “Low temperature activity” is claimed in the IFU.

5.7 “Globe valve” glove dexterity practical performance test
This test is mandatory for ET garments in 6.1 and mandatory for any other kind garments depending on
intended uses.
The objective of this exercise is to verify that the wearing of a chemical protective garment, including
gloves, does not impair the wearer’s ability to carry out a simple mechanical task to the extent that the task
becomes impossible. The requirements shall be carried out according to clause 6 (including the number of
samples and number of persons needed). The test shall be carried out on two samples by two test subjects
(preferably two different ones), in addition to any other required PPE for the task (e.g. face mask, RPD).
The test subject shall be familiar with the test apparatus and shall be capable of completing the exercise
easily when not wearing a chemical protective suit.
The apparatus shall consist of a short (approximately 1 m) length of nominal 2” (DN 50) internal diameter
steel pipe mounted horizontally above a bench in an orientation parallel to the front edge of the bench. The
bench surface shall be (1 ± 0,1) m above floor level. The pipe shall be fixed to the bench by means of fixing
brackets such that the centreline of the pipe is (0,10 ± 0,01) m above the bench and (0,25 ± 0,025) m behind
the vertical plane of the edge of the bench.
The pipe shall be terminated in a flange-fitting that can accommodate four M16 bolts. The holes in the flange
shall not be threaded. The orientation of the holes shall be such that a line between any two circumferentially
adjacent holes shall be either vertical or ho
