Protective clothing for protection against chemicals - Classification, labelling and performance requirements - Part 3: Chemical test methods, classification and requirements (ISO/DIS 16602-3:2025)

This document specifies the chemical performance classification and test methods for materials used in
chemical protective clothing, including gloves and footwear. The gloves and boots should have the same
minimum chemical protective barrier requirements as the fabric when they are an integral part of the
clothing.
While these performance levels are intended to relate to the usage to which the chemical protective
clothing is to be put, it is essential that the chemical protective clothing manufacturer or supplier indicate
the intended use of the protective clothing and that the user (specifier) carries out a risk assessment in
order to establish the correct performance level for the intended task.

Schutzkleidung gegen Chemikalien - Klassifizierung, Kennzeichnung und Leistungsfähigkeit - Teil 3: Chemische Testmethoden, Klassifizierung und Anforderungen (ISO/DIS 16602-3:2025)

Dieses Dokument legt die chemische Leistungseinstufung und Prüfverfahren für Materialien fest, die in Chemikalienschutzkleidung, einschließlich Handschuhen und Schuhwerk, verwendet werden. Die Handschuhe und das Schuhwerk müssen dieselben Mindestanforderungen an die chemische Schutzwirkung [einschließlich Feststoffen, luftgetragener Partikel, Aerosole, Flüssigkeiten und Gase (einschließlich radioaktiver Kontaminationsstoffe)] erfüllen wie der Bekleidungsstoff, wenn sie fester Bestandteil der Kleidung sind.
Obwohl es das Ziel dieser Leistungsstufen ist, eine Beziehung zu der Verwendung herzustellen, bei der die Chemikalienschutzkleidung zu tragen ist, ist es wichtig, dass der Hersteller oder Lieferant der Chemikalienschutzkleidung die vorgesehene Verwendung der Schutzkleidung angibt und dass der Anwender (Ersteller von Spezifikationen) eine Risikobewertung durchführt, um die richtige Leistungsstufe für die vorgesehene Aufgabe festzulegen.

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).
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent
rights identified during the development of the document will be in the Introduction and/or on the ISO list of
patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

related to conformity assessment, as well as information about ISO's adherence to the World Trade
Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 94, Personal safety—Personal protective
equipment, Subcommittee SC 13, Protective clothing.
This second edition cancels and replaces the first edition ISO 16602:2007. The standard has completely been
rewritten and split into parts, with the most significant changes compared to the previous edition relating
to: (1) a new modular approach, (2) marking, (3) chemical protection.
