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.

ISO/TS 16973 was prepared by Technical Committee ISO/TC 94, Personal safety — Protective clothing and equipment, Subcommittee SC 15, Respiratory protective devices.

Introduction

This Technical Specification contains the classification of Respiratory Protective Devices (RPD) and the related marking in accordance with the requirements of the performance standards.

The basic classification, which applies to all RPD, will be marked in the following order:

• a) protection class;
• b) work rate class;
• c) respiratory interface class.

Some examples for marking of commonly known RPD are included in Annex B.

For Supplied Breathable Gas RPD, the classification also includes gas capacity class.

For Filtering RPD, the classification also includes a particle filter class and/or the gas filter types and classes.

RPD designated to be used for Special Applications are further classified accordingly.

The special applications identified are

• Firefighting,
• Chemical, Biological, Radiological and Nuclear (CBRN),
• Marine,
• Mining,
• Abrasive blasting,
• Welding, and
• Escape.

Each RPD will have an individual classification based on its performance specified in the relevant performance standards.

Explanations of the classification and examples of the classification of RPD are given in the Annexes.

The following definitions apply in understanding how to implement an ISO International Standard and other normative ISO deliverables (TS, PAS, IWA):

• “shall” indicates a requirement;
• “should” indicates a recommendation;
• “may” is used to indicate that something is permitted;
• “can” is used to indicate that something is possible, for example, that an organization or individual is able to do something.

3.3.1 of the ISO/IEC Directives, Part 2 (sixth edition, 2011) defines a requirement as an “expression in the content of a document conveying criteria to be fulfilled if compliance with the document is to be claimed and from which no deviation is permitted.”

3.3.2 of the ISO/IEC Directives, Part 2 (sixth edition, 2011) defines a recommendation as an “expression in the content of a document conveying that among several possibilities one is recommended as particularly suitable, without mentioning or excluding others, or that a certain course of action is preferred but not necessarily required, or that (in the negative form) a certain possibility or course of action is deprecated but not prohibited.”
