Protective clothing for protection against chemicals - Classification, labelling and performance requirements - Part 1: General requirements (ISO/DIS 16602-1:2025)
This document specifies minimum performance classification and labelling requirements for protective clothing designed to provide protection against:
- specified chemicals in the workplace, and
- unidentified chemicals in emergency situations.
Protective clothing against chemicals including solids, airborne particles, aerosols, liquids, and gases is addressed by this document.
Protective clothing items covered by this document include full body and partial body. The area of protection is denoted in the marking requirements. The ISO 16602 series allows for a modular approach.
This document sets the general requirements and the rules for applying the modular approach. The other parts focus on requirements and classification from design, chemical, physical properties and full garment testing perspectives. The seams, joins and assemblages attaching the components (including accessories) are included within the scope of this series of standards. ISO 16602-6 provides a Selection, Care and Maintenance guide to help the end-user selection process.
Chemicals such as violently air sensitive reagents, unstable explosives and cryogenic liquids have not been considered since protection against these additional hazards is beyond the scope of this standard.
Particulate protection is limited to physical penetration of the particulates only; permeation of solids is not considered.
This document does not address components such as gloves, boots, eye/face protection devices and respiratory protective devices as their performance criteria are given in other standards. However, when these components are an integral part of the protective clothing ensemble or are tested as part of an ensemble, supplementary requirements may be provided in this standard.
This document does not specifically address non-chemical hazards, such as biological and infective agents, thermal (flame, heat or cold) hazards, explosive hazards, and ionizing radiation hazards as specific requirements are covered by other relevant standards. The type of equipment specified in this series of standards is not intended for total immersion in liquids. However, additional protection may be integrated as a specific module based on the respective standard (e.g. meeting both ISO 16602-1 & ISO 11612 in a multi-risk suit).
It is not the intent of this series of documents to be exhaustive and address all situations.
Schutzkleidung gegen Chemikalien - Klassifizierung, Kennzeichnung und Leistungsfähigkeit - Teil 1: Allgemeines (ISO/DIS 16602-1:2025)
Dieses Dokument legt Mindestanforderungen an die Klassifizierung der Leitungsfähigkeit und die Kennzeichnung von Schutzkleidung fest, die aufgrund ihrer Gestaltung Schutz bietet gegen:
festgelegte Chemikalien am Arbeitsplatz; und
nicht identifizierten Chemikalien in Notfallsituationen.
In diesem Dokument wird Schutzkleidung gegen Chemikalien behandelt, einschließlich Feststoffen, luftgetragener Partikel, Aerosolen, Flüssigkeiten und Gasen (einschließlich radioaktiver Kontamination). Ob gegen Chemikalien oder radioaktive Kontaminationsstoffe in Form von Feststoffen, luftgetragenen Partikeln, Aerosolen, Flüssigkeiten oder Gasen wird mittels der Prüfung von Kleidungsstücken deren Schutz bewertet. Dieses Dokument muss in Verbindung mit den folgenden Normen angewendet werden: ISO/DIS 16602 2, ISO/DIS 16602 3, ISO/DIS 16602 4 und ISO/DIS 16602 5.
Von diesem Dokument abgedeckte Schutzkleidungsstücke schließen Ganzkörperschutzkleidung und Teilkörperschutzkleidungsstücke ein. Der Schutzbereich ist in den Anforderungen an die Kennzeichnung angegeben. Die Normenreihe ISO 16602 verfolgt einen modularen Ansatz, um den Mindestschutz gegen Chemikalien zu erhöhen. Dieses Dokument legt die allgemeinen Anforderungen und die Regeln zur Anwendung des modularen Ansatzes fest. Die zusätzlichen Schutzeigenschaften werden in der Kennzeichnung und der Gebrauchsanweisung angegeben. Die anderen Dokumente in dieser Normenreihe konzentrieren sich auf die Anforderungen und Klassifizierung aus Sicht der Gestaltung, der chemischen und physikalischen Eigenschaften und der Prüfung von Kleidungsstücken.
Die Nähte, Verbindungen und Verbünde zum Anbringen der Bestandteile (einschließlich Zubehörteilen) liegen innerhalb des Anwendungsbereichs dieser Normenreihe. ISO/DIS 16602 6 stellt eine Anleitung für die Auswahl, Pflege und Wartung bereit, um den Endanwender beim Auswahlprozess zu unterstützen, und gibt außerdem auch einen Überblick über die Normenreihe ISO 16602.
Chemikalien wie stark luftempfindliche Reagenzien, instabile Explosivstoffe und kryogene Flüssigkeiten wurden nicht berücksichtigt, da der Schutz gegen diese zusätzlichen Gefährdungen außerhalb des Anwendungsbereichs dieser Norm liegt. Der Schutz vor Partikeln ist lediglich auf die physikalische Durchdringung der Partikel beschränkt; die Permeation von Feststoffen wird nicht berücksichtigt.
Dieses Dokument behandelt nicht solche Bestandteile wie Handschuhe, Stiefel, Augen-/Gesichtsschutzeinrichtungen und Atemschutzgeräte, da deren Leistungskriterien in anderen Normen festgelegt sind. Wenn diese Bestandteile jedoch ein fester Bestandteil des Schutzkleidungssystems sind oder als Teil eines Kleidungssystems geprüft werden, sind in dieser Norm möglicherweise ergänzende Anforderungen angegeben.
Dieses Dokument behandelt nicht eigens nicht-chemische Gefährdungen, wie z. B. Gefährdungen durch biologische Agenzien und Infektionserreger, thermische Gefährdungen (Flammen, Wärme oder Kälte), Explosionsgefährdungen und Gefährdungen aufgrund ionisierender Strahlung (mit Ausnahme von radioaktiver Kontamination), da spezifische Anforderungen von anderen maßgebenden Normen abgedeckt werden. Die Art der in dieser Normenreihe festgelegten Ausrüstung ist nicht für den Schutz gegen vollständiges Eintauchen in Flüssigkeiten vorgesehen. Jedoch darf zusätzlicher Schutz als ein spezifisches Modul basierend auf der entsprechenden Norm einbezogen werden (z. B. Übereinstimmung sowohl mit ISO/DIS 16602-1 als auch ISO 11612 bei einem Schutzanzug für mehrere Risiken).
Diese Normenreihe beansprucht nicht, vollständig zu sein und behandelt nicht alle möglichen Szenarien.

Introduction
This document addresses the range of industrial chemical protective clothing by designating specific
design types and providing classification of clothing, material, and component performance. This document
is intended to provide comprehensive requirements for the performance classification and labelling of
chemical protective clothing.
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 series of documents is intended to provide a modular approach to design and specification for chemical
protective clothing accommodating the variety and severity of risks 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 Type 1 through Type 6 garments were originally created to differentiate garment performance through
a specific garment test(s): These “Type” garments could not be placed in an intrinsic hierarchy, although
the fabric barrier performances (intrinsic properties of the fabric and seams) created an indirect hierarchy
in certain cases. For example, Type 1 is in general more protective than Type 2, Type 5 and Type 6; and
Type 3 is, in general, more protective than Type 4 and Type 6. Although the Type 1-Type 6 system has been
superseded by the modular approach, a correlation table will be available in ISO/DIS 16602-6.
In the previous ISO 16602 (and EN equivalents EN 13034, EN 14605, EN 943 series, EN 1073 series, and
EN 14325), there is a link between the garment tests, the Type (Type 1 through Type 6), and the physical
and chemical requirements of materials and components. This revision of the ISO 16602 series (intended
to be an EN ISO standard), applies a modular approach that breaks that link. Nevertheless, the existing test
methods from ISO 16602 and in other European standards (e.g. EN 14325:2018) have been used as the basis
for this revision.
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.

Protective clothing for protection against chemicals —
Classification, labelling and performance requirements —
Part 1:
General requirements
1 Scope
This document specifies minimum performance classification and labelling requirements for protective
clothing designed to provide protection against:
— specified chemicals in the workplace, and
— unidentified chemicals in emergency situations.
Protective clothing against chemicals including solids, airborne particles, aerosols, liquids, and gases
(including radioactive contamination) is addressed by this document. Whether for chemicals or radioactive
contaminants in the form of solids, airborne particles, aerosols, liquids, or gases, their protection is
assessed using the garment test. This document shall be used in conjunction with the following standards:
ISO/DIS 16602-2, ISO/DIS 16602-3, ISO/DIS 16602-4 and ISO/DIS 16602-5.
Protective clothing items covered by this document include full body and partial body. The area of
protection is denoted in the marking requirements. The ISO 16602 series allows for a modular approach for
increasing the minimum chemical protection. This document sets the general requirements and the rules
for applying the modular approach. The additional protective properties are indicated in the marking and
the instructions for use. The other documents in this series focus on requirements and classification from
design, chemical, physical properties and garment testing perspectives.
The seams, joins and assemblages attaching the components (including accessories) are included within the
scope of this series of standards. ISO/DIS 16602-6 provides a Selection, Care and Maintenance guide to help
the end-user selection process and also gives a thorough overview of the ISO 16602 series.
Chemicals such as violently air sensitive reagents, unstable explosives and cryogenic liquids have not
been considered since protection against these additional hazards is beyond the scope of this standard.
Particulate protection is limited to physical penetration of the particulates only; permeation of solids is not
considered.
This document does not address components such as gloves, boots, eye/face protection devices and
respiratory protective devices as their performance criteria are specified in other standards. However,
when these components are an integral part of the protective clothing ensemble or are tested as part of an
ensemble, supplementary requirements may be provided in this standard.
This document does not specifically address non-chemical hazards, such as biological and infective agents,
thermal (flame, heat or cold) hazards, explosive hazards, and ionizing radiation hazards (other than
radioactive contamination) as specific requirements are covered by other relevant standards. The type
of equipment specified in this series of standards is not intended for protection against total immersion
in liquids. However, additional protection may be integrated as a specific module based on the respective
standard (e.g. meeting both ISO/DIS 16602-1 & ISO 11612 in a multi-risk suit).
It is not the intent of this series of documents to be exhaustive and address all possible scenarios.

4 General requirements
4.1 General
Any garment and its component shall meet all the requirements of ISO 13688 in addition to the
requirements set in this document and as defined in ISO/DIS 16602-2, ISO/DIS 16602-3, ISO/DIS 16602-4,
and ISO/DIS 16602-5.
This ISO/DIS 16602-1 to ISO/DIS 16602-5 series is intended to provide a modular approach to design and
specification for chemical protective clothing accommodating the variety and severity of risk found, and
activities carried out in the workplace.
NOTE ISO/DIS 16602-6 does not have any requirements, but provides an explanation for how some of the
requirements may be used by the user or purchaser to define their criteria and needs for selection, use, care and
maintenance. ISO 16602 is also intended to reconcile the differences with the previous ISO and EN standards.
This document requires that materials of construction and components of the suit be tested for resistance
to the chemical and mode of ingress. In cases where more than one chemical is tested, each component and
material of construction shall be tested against each chemical.
4.2 Chemical compatibility between suits and components
The levels of chemical protection afforded by the suit materials, and various components and accessories
are unlikely to be identical.
The chemical protective performance of each suit material, accessory and component that is part of the
chemical protective envelope around the wearer shall be reported in the manufacturer’s instructions (IFU).
The chemical protection performance shall be defined by the results obtained from the test methods in
this document. The manufacturer shall also define which components are required in order to provide that
performance.
EXAMPLE An ensemble has a defined protection against 20 chemicals. The ensemble includes a single suit and
allows for 5 different attachable gloves. Between the five gloves, they provide protection against all the 20 chemicals.
Each glove separately protects against 6 chemicals. The IFU of the ensemble will have the chemical protection
performance of the suit and the chemical protection performance for the five different gloves that must as minimum
provide a chemical protection that is equivalent or better than the rating that is achieved by the suit for the defined
20 chemicals. The user will then be able to choose the appropriate glove for the protection required based on the 20
chemicals.
4.3 Requirements for pre-treatment and conditioning for testing
4.3.1 Cleaning
Before each test, all chemical protective clothing material samples, with the exception of limited-use
chemical protective clothing, shall undergo pre-treatment by cleaning and disinfection.
For materials, which require pre-treatment by cleaning and disinfection, the performance classification shall
be based on the lowest/worst performance classification obtained on testing as new (not pre-treated) and
pre-treated materials. If insufficient documented evidence (i.e. previous test data) is available to determine
whether the test shall be performed as new or pre-treated, the test shall be performed in both conditions.
If the manufacturer’s instructions indicate that cleaning or disinfection is not allowed, i.e. limited use
garments, then testing shall be carried out on new material or a new garment.
Where applicable according to manufacturer’s instructions, the hygienic cleaning and disinfection shall
be in line with the manufacturer’s instructions, on the basis of standardized procedures. If the number of
cleaning and disinfection cycles is not specified, the tests shall be carried out after 5 cycles of cleaning. Each
cycle shall consist of one wash cycle, one dry cycle and one disinfection cycle carried out as indicated by the
manufacturer’s instructions.
ISO/DIS 16602-1:2025(en)
Manufacturer’s instructions with regard to number of cleaning cycles, cleaning procedures and possible
reapplication of treatments (e.g. repellency) shall be observed, potentially including sterilisation.
NOTE Cleaning is not the same as decontamination. Decontamination is not part of pre-conditioning or pre-
treatment.
4.3.2 Conditioning
All samples shall be conditioned by storage at (23 ± 3) °C and (60 ± 10) % relative humidity for at least 24 h.
Testing of samples shall commence within 10 min of removing the sample from the conditioning atmosphere,
unless otherwise indicated in the test method standard.
This conditioning requirement takes priority over any conflicting conditioning requirements in the
individual test method standards.
Conditioning may be omitted or aligned with the conditions of 4.3.3, if it can be shown that test results are
not affected by the foreseeable changes of temperature and relative humidity.
4.3.3 Testing temperature
Unless otherwise specified in this series of standards, all testing shall be conducted at the same conditions
used for conditioning specified in 4.3.2.
Chemical permeation testing shall be conducted at (23 ± 1) °C.
This testing temperature requirement takes priority over any conflicting temperature requirements in the
individual test method standards.
4.3.4 Simulation of extreme storage conditions
Foreseen or normal storage conditions are provided according to the IFU (11.2 b); if extreme storage
conditions are applicable these shall also be included in the IFU.
Extreme storage conditions are defined as temperature ≥ 60 °C and ≤ -30 °C.
If the manufacturer claims extreme storage conditions in the IFU, two garments shall be exposed, in the
original packaging. For a period of no less than 24 h, the garments shall be exposed to the highest claimed
temperature and at (95 ± 5) % relative humidity. After being allowed to return to ambient temperature, the
garments shall be exposed for no less than 24 h to the lowest claimed temperature.
After the extreme storage exposure, the garments shall be allowed to return to ambient temperature. The
garments shall be tested according to 4.3.3 using the minimum practical performance test defined in 7.5 and
in ISO/DIS 16602-5: — (5).
A visual inspection shall be carried out prior to subsequent testing. Any changes to the garment’s appearance
or characteristic (compared to normal conditioning in 4.3.3 or as received) shall be noted in the test report.
4.3.5 Deterioration of repellency by cleaning
Where the finishing, applied to improve or maintain the liquid repellency performance of the garment, can
be deteriorated by the cleaning procedures indicated by the manufacturer, the manufacturer shall indicate
the maximum number of cleaning cycles that can be carried out before the garment needs to be re-treated
or re-impregnated to restore its performance.
Testing according to ISO/DIS 16602-3 clause 7 shall be carried out before the cleaning cycle for which the
manufacturer guarantees the performance.
For example, if the instructions state “re-impregnation during each third cleaning cycle”, tests shall be
performed after the second cleaning cycle, i.e. before re-impregnation. Then after reimpregation is applied,
the test should be performed again in order to demonstrate meeting the requirement.
ISO/DIS 16602-1:2025(en)
If the instructions state “re-impregnation after each cleaning cycle”, the tests shall be performed on new
items. Later, the item shall be cleaned, reimpregnation is applied and testing repeated again in order to
demonstrate meeting the requirement.
In all cases, cleaning shall be performed according to 4.3.1.
5 Physical requirements
Chemical protective clothing materials shall be tested and classified according to the physical requirements
of ISO/DIS 16602-2, unless specified differently in ISO/DIS 16602-4.
To meet the minimum requirements of this document, unless specified differently in ISO/DIS 16602-4, a
class 1 for each of the core physical requirements, as defined in Table 1, shall be met. Classification shall be
according to the classification of ISO/DIS 16602-2.
Table 1 — Core physical requirements
Core Physical Requirements
Abrasion resistance
Flex cracking resistance
Tear resistance
Tensile strength
Puncture resistance
Seam strength
The garment physical average properties shall also be marked with the symbol in Figures B.3.1 and B.3.2
according to the requirements of this document (see Annex B.3).
This marking will be used in conjunction with a number in the upper right-hand side that provides the average
of the classes of core physical requirements as defined by this clause. This number will be rounded down to
the integer. The individual results of the mechanical tests shall be mentioned in the instructions for use.
Table 2 — Example of physical property calculation
Mechanical Result Class
Abrasion >10 1
Flex cracking >1 000 1
Tear >40 3
Tensile >60 2
Puncture >5 1
Seam >50 2
Average of the classes 1,67
Integer part 1
In this example of Table 2, the digit would be “1” rather than “2” (i.e. the integer part of the calculated average
of the classes), thus giving the marking in figure B.3.1 (upper right-hand corner), in Annex B.
6 Chemical ingress requirements
As a minimum, a garment shall meet the garment design requirements of ISO/DIS 16602-4, the corresponding
garment test of ISO/DIS 16602-5 and the minimum chemical ingress requirements in ISO/DIS 16602-3.
NOTE For example, a gas tight suit would need to at least meet the design requirement of the pressure tight
design, meet the garment test of ISO 17491-1 according to ISO/DIS 16602-5, and the fabrics, seams, etc. need to meet at
least the minimum requirement of ISO/DIS 16602-3 for permeation (barrier Class A).
ISO/DIS 16602-1:2025(en)
Chemical protective garments and materials shall be tested as defined in Table 3. Some of these designs allow
for partial body (PB) protection as defined in ISO/DIS 16602-1:—, (7.3); these need to meet the corresponding
design requirements of ISO/DIS 16602-4 and meet the respective garment test of ISO/DIS 16602-5, and the
fabrics, seams, etc. need to meet at least the minimum corresponding requirements of ISO/DIS 16602-3.
NOTE Requirements for partial body protection, when permitted, are the same as for full body protection (see
7.3.2 (2) and (3)).

If a garment meets the requirements of more than one garment design, it shall meet the full requirements of
each garment design.
NOTE For example, if a garment is intended to meet both liquid spray resistant design and liquid mist resistant
design, it is required to pass both garment design tests. In addition, it is also required to pass both penetration and
permeation tests for the same chemical(s).
The marking shall utilise the garment test pictograms shown in Annex B.1. The chemical ingress marking
shown in Annex B.2 shall be provided according to the relevant test results and classified according to
ISO/DIS 16602-3. At least one of the four chemical ingress minimum requirements shall be met as defined in
Table 3.
ISO/DIS 16602-1:2025(en)
7 General requirements for garments
7.1 General
Any garment, full body or partial body, complying with the general requirements of this document shall also
specifically meet a set of minimum requirements relating to the physical requirements of clause 5 (tested
in accordance with ISO/DIS 16602-2), the chemical ingress requirements of clause 6 (tested in accordance
with ISO/DIS 16602-3) and the design requirement as determined by ISO/DIS 16602-4. The garment test
