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 addresses the selection, use, care and maintenance (SUCAM) of chemical protective clothing
and also links the old classification to the new modular approach. This document is intended to provide
comprehensive explanation of the requirements for the performance classification and labelling of chemical
protective clothing and how these may apply in the workplace.
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withdrawn.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 performances through
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 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) have been used as the basis for
this revision.
The selection of appropriate chemical protective clothing is strongly advised to 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 identify the chemical
protective clothing required in terms of its overall performance requirements from physical characteristics,
chemical protection and whole 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 6:
Guidance for Selection, Use, Care and Maintenance
1 Scope
This document addresses the selection, use, care and maintenance (SUCAM) of chemical protective clothing
(CPC). This guidance document is primarily intended for users, specifiers and others with responsibility
for the procurement and provision of chemical protective clothing. It is also intended to be used by
manufacturers in their dialogue with the users of PPE.
This guidance document is intended to clarify the inter-relationship between this ISO 16602 series of
standards and its modular approach, ISO 17723-1 but also how this links to the old classification of CPC.
These guidelines are intended to assist users and specifiers in selecting the correct type of CPC for the
task to be performed, and to help them ensure it is used according to the manufacturer's instructions to
provide adequate chemical protection (including solids, airborne particles, aerosols, liquids, and gases
(including radioactive contamination)) during its entire lifetime. Lifetime and effectiveness of protective
clothing depend largely on care and maintenance. When cleaning, disinfection and end-of-life disposal are
considered, the environmental impact should also be taken into account.
To assist the users of products covered under this document, this document provides descriptions of
referenced test methods, guidelines for conducting hazard and risk assessments and suggested performance
levels for certain applications. It is not the intent of this document to address all potential situations.
NOTE Although this document has been created as a stand-alone document covering ISO/DIS 16602-1 through
ISO/DIS 16602-5, it is strongly recommended to read this guidance in conjunction with ISO/DIS 16602-1 (if not the
other parts) to understand the detail of the requirements.

3.1.2 Definitions specific to this document
NOTE The source of these definitions are from respective test methods and ISO 11610
3.1.2.1
ageing
change of one or more initial properties of the materials during the passage of time
[SOURCE: ISO 11610:2023, 4.6.13]
3.1.2.2
air-impermeable materials
materials through which gases cannot pass except by a diffusion process on a molecular level
3.1.2.3
air-permeable materials
materials with pores or apertures that allow the transmission of gases
3.1.2.4
breakthrough (detection) time
time elapsed from the start of the test to the sampling time at which the test chemical is first detected
Note 1 to entry: The breakthrough detection time is dependent on the sensitivity of the method and the frequency of
sampling of the collection medium
[SOURCE: ISO 11610:2023, 7.5.22]
3.1.2.5
care
process of keeping the protective garments in good working order, including procedures for cleaning,
decontamination and storage
[SOURCE: ISO 11610:2023, 15.3]
3.1.2.6
chemical hazard
potential of a chemical to cause harm or damage to a person's health or to the human body
3.1.2.7
challenge chemical
test chemical
liquid or gas that is used to challenge the protective material specimen when testing
Note 1 to entry: The liquid or gas may be either one component, i.e. a neat liquid or gas, or have several components,
i.e. a mixture or solution.

3.1.2.8
cumulative permeation mass
cumulative permeation time
time at which the total quantity of chemical that has permeated through each square centimetre of fabric
(4.3.1) has reached a predetermined masstotal amount of chemical that permeates during a specified period
of time since the start of the test
Note 1 to entry: See Figure 1.

3.1.2.9
degradation
deleterious change in one or more physical properties of a protective material
EXAMPLE Flaking, swelling, disintegration, embrittlement (6.5.6) , colour change, dimensional change,
appearance change, hardening, softening.

3.1.2.11
maintenance
protective garments process for inspection, care and repair with the aim of retaining the protective
properties and preventing excessive deterioration of the garments
[SOURCE: ISO 11610:2023, 15.4]
3.1.2.12
normalized breakthrough (detection) time
NBT
time at which the permeation rate reaches the normalization permeation rate
Note 1 to entry: See Figure 1.
