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. 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. 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.

The committee responsible for this document is ISO/TC 94, Personal safety - Protective clothing and equipment, Subcommittee SC 15, Respiratory protective devices.

ISO 16900 consists of the following parts, under the general title Respiratory protective devices — Methods of test and test equipment:

• Part 1: Determination of inward leakage
• Part 2: Determination of breathing resistance
• Part 3: Determination of particle filter penetration
• Part 4: Determination of gas filter capacity and migration, desorption and carbon monoxide dynamic testing
• Part 11: Determination of field of vision

The following parts are under preparation:

• Part 5: Breathing machine/metabolic simulator/RPD headforms/torso, tools and transfer standards
• Part 6: Mechanical resistance – Strength of components
• Part 7: Practical performance test method
• Part 8: Measurement of RPD air flow rates
• Part 9: Determination of the carbon dioxide content of inhaled air
• Part 10: Resistance to ignition, flame, radiant heat and heat
• Part 12: Determination of volume averaged work of breathing and peak respiratory pressures
• Part 13: RPD using regenerated breathable gas and special application mining escape RPD: Consolidated test for gas concentration, temperature, humidity, work of breathing, breathing resistance and duration

Introduction

This part of ISO 16900 is intended as a supplement to the respiratory protective devices (RPD) performance standard ISO 17420 (all parts). Test methods are specified for complete devices or parts of devices that are intended to comply with ISO 17420. If deviations from the test method given in this part of ISO 16900 are necessary, these deviations will be specified in ISO 17420.

1 Scope

This part of ISO 16900 specifies the laboratory test method for determining the field of vision for a respiratory protective device (RPD).
