Protective clothing for protection against chemicals - Classification, labelling and performance requirements - Part 4: Test methods, classification and requirements for specific designs and ensemble components including gloves, footwear, and respirators (ISO/DIS 16602-4:2025)

This document specifies minimum design and functional performance requirements for protective clothing
against specified chemicals in the workplace and unidentified chemicals in emergency situations. These
requirements cover all relevant parts of the ensemble which are attached/fitted to the chemical protective
clothing for example garment, visor, gloves, boots or bootees, ventilation (non-breathing), and other design
features.
This document does not specifically address protection against biological, thermal (flame, heat or cold), and
ionizing radiation hazards as specific requirements are covered by other relevant standards.

Schutzkleidung gegen Chemikalien - Klassifizierung, Kennzeichnung und Leistungsfähigkeit - Teil 4: Design

Dieses Dokument legt Mindestanforderungen an die Gestaltung und funktionelle Leistungsfähigkeit von Schutzkleidung gegen festgelegte Chemikalien [einschließlich Feststoffe, luftgetragene Partikel, Aerosole, Flüssigkeiten und Gase (einschließlich radioaktiver Kontamination)] am Arbeitsplatz sowie nicht identifizierte Chemikalien in Notfallsituationen fest. Diese Anforderungen decken alle maßgeblichen Teile des Kleidungssystems ab, die an der Chemikalienschutzkleidung befestigt/angebracht sind, zum Beispiel Kleidungsstück, Sichtscheibe, Handschuhe, Stiefel oder Füßlinge, Lüftung (nicht atmend) und weitere Gestaltungsmerkmale.
Dieses Dokument behandelt nicht speziell den Schutz gegen biologische, thermische (Flammen, Hitze oder Kälte) Gefährdungen und Gefährdungen durch ionisierende Strahlung, da diesbezügliche spezifische Anforderungen von anderen maßgebenden Normen abgedeckt werden.
Diese Art der Ausrüstung ist nicht für das Eintauchen in Flüssigkeiten vorgesehen.
Die grundlegenden Leistungskriterien für die Bestandteile wie z. B. Handschuhe, Schutzstiefel oder Atemschutzgeräte sind in anderen Normen angegeben. Ergänzende Anforderungen werden in dieser Norm bereitgestellt.
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.

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

Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.

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.

Introduction
This document addresses the design requirements for chemical protective clothing by designating specific
design types and providing classification of clothing, material, and component performance. This document
is intended to provide comprehensive design requirements for the performance of chemical protective
clothing together with ISO/DIS 16602-1 and ISO/DIS 16602-5.
This document is part of a series of standards for test methods and requirements for both limited use and
reusable chemical protective clothing. ISO/DIS 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, a
