Full title and description

ISO 16976-8:2023 — Respiratory protective devices — Human factors — Part 8: Ergonomic factors. This International Standard provides guidance on generic ergonomic factors for respiratory protective devices (RPD), including principles for biomechanical interaction between RPD and the human body and for interaction with human senses (vision, hearing, smell, taste and skin contact). It does not set hazard-specific performance requirements.

Abstract

This document describes requirements and guidance on factors related to human physiology, ergonomics and performance to be used when preparing standards for design, testing and use of respiratory protective devices. It focuses on generic ergonomic considerations such as fit, biomechanical loading, and sensory interactions rather than on hazard-specific criteria.

Scope

Provides guidance for the incorporation of ergonomic factors into standards for respiratory protective devices. Topics covered include biomechanical interactions (fit, contact pressures, head/neck loads), sensory interactions (vision, hearing, smell, taste, skin contact), and general ergonomic principles to inform design, testing and user use. The document excludes requirements that are specific to particular hazard types for which RPD are intended.

Key topics and requirements

• Principles for biomechanical interaction between RPD and the human body (fit, seal, contact pressure, load distribution).
• Ergonomic considerations for head, neck and facial interface design to minimise discomfort and injury risk.
• Guidance on visual field and optical interference caused by facepieces and visors.
• Considerations for hearing and speech intelligibility when using RPD.
• Effects of skin contact, tactile feedback and chemical/olfactory interactions relevant to comfort and acceptability.
• Generic recommendations to inform standard writers on human factors aspects for testing and performance requirements.

These topics summarize the standard’s guidance for designers, testers and standards developers.

Typical use and users

Used by standards committees and technical writers preparing RPD performance and test standards; RPD manufacturers and designers integrating human factors into product design; test laboratories developing ergonomic test protocols; occupational health and safety practitioners and ergonomists advising on selection and use; and regulators referencing ergonomic guidance for conformity assessment.

Related standards

Part of the ISO 16976 series addressing human anthropometry, physiology, ergonomics and performance for respiratory protective devices (other parts cover metabolic flow rates, thermal effects, hearing and speech, etc.). It is related to ISO/TC 94/SC 15 outputs and to performance standards for RPD (for example the ISO 17420 series). Users should consult other parts of ISO 16976 for complementary topics (e.g., thermal effects in ISO 16976-5).

FAQ

Q: What is this standard?

A: ISO 16976-8:2023 is an international standard that provides guidance on ergonomic factors to be considered when preparing standards and requirements for respiratory protective devices.

Q: What does it cover?

A: It covers generic ergonomic principles including biomechanical interactions (fit, contact pressure, head/neck loads) and interactions with human senses (vision, hearing, smell, taste and skin contact). It does not cover hazard-specific performance requirements.

Q: Who typically uses it?

A: Standards developers, RPD manufacturers and designers, test laboratories, occupational health and safety professionals, ergonomists and regulators reference this standard when addressing human factors for respiratory protective equipment.

Q: Is it current or superseded?

A: It is current (published 3 February 2023). It replaces and updates the earlier technical specification ISO/TS 16976-8:2013, which has been withdrawn.

Q: Is it part of a series?

A: Yes — it is Part 8 of the ISO 16976 series on human anthropometry, physiology, ergonomics and performance for respiratory protective devices; other parts in the series address related topics such as thermal effects, metabolic flow rates and hearing/speech.

Q: What are the key keywords?

A: Respiratory protective devices, human factors, ergonomics, biomechanical interaction, fit, vision, hearing, skin contact, anthropometry.
