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, 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, 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.

This document was prepared by Technical Committee ISO/TC 94 Personal safety - Personal protective equipment, Subcommittee SC 15, Respiratory protective devices.

This first edition of ISO 16976-2 cancels and replaces ISO/TS 16976-2:2015, which has been technically revised.

The main changes are as follows:

• Figure 6 changed to show head forms front and side view (see ISO 16900-5:2016/Amd 1:2018);
• the document has been editorially revised.

A list of all parts in the ISO 16976 series can be found on the ISO website.

Introduction

For an appropriate design, selection, and use of respiratory protective devices, basic physiological demands of the user should be considered. Type and intensity of work affect the metabolic rate (energy expenditure) of the wearer. Mass and mass distribution of the device on the human body can also influence metabolic rate. Metabolic rate is directly correlated with oxygen consumption, which determines the respiratory demands and flow rates. The work of breathing is influenced by the air flow resistances of the device and the lung airways. The work (or energy cost) of a breath is related to the pressure gradient created by the breathing muscles and the volume that is moved in and out of the lung during the breath. Anthropometric and biomechanical data are required for appropriate design of various components of a respiratory protective device, as well as for the design of relevant test methods.

This document forms one part of a series of documents providing basic anthropometric measurement methods and data on humans. It contains information about the description, definition, and diagram of landmarks and dimensions, up-to-date head and face data for various race/ethnic groups, and human test panels.

1 Scope

This document is one part of the ISO 16976 series that provide information on factors related to human anthropometry, physiology, ergonomics, and performance for the preparation of standards for design, testing, and use of respiratory protective devices.

This document contains information related to anthropometry. In particular, information is given for:

• anthropometric measurement methods;
• anthropometric data for head, face, and neck dimensions;
• anthropometric data for torso dimensions;
• human test panels;
• models of headforms.
