Full title and description

SA/SNZ TS ISO 16976.6:2021 — Respiratory protective devices — Human factors — Psycho‑physiological effects. National technical specification adopting the ISO/TS text that gives guidance on the psycho‑physiological responses and considerations related to wearing respiratory protective devices (RPD). Intended to help standards writers, manufacturers, safety professionals and trainers address wearer comfort, acceptance and related human factors when selecting, designing and using RPD.

Abstract

This technical specification provides information on psycho‑physiological effects associated with the use of respiratory protective devices. It describes principles for the interaction between RPD and human physiological and psychological perception, identifies factors that affect wearer comfort and acceptance, and highlights the role of training and organisational measures in improving effective use. The document is not a performance standard for specific hazards and does not specify numeric protection requirements; rather, it informs the development of selection, use and testing standards and guidance.

General information

• Status: Superseded (national adoption of an ISO/TS text; subsequently updated at international and national levels).
• Publication date: 28 May 2021.
• Publisher: Standards Australia / Standards New Zealand (joint technical specification adoption).
• ICS / categories: 13.340.30 — Respiratory protective devices; Human factors in personal protective equipment.
• Edition / version: Technical Specification — first Australian/New Zealand adoption (identical adoption of ISO/TS 16976‑6:2014).
• Number of pages: 14 pages (national TS document).

Scope

The TS gives guidance for writers of RPD standards and for organisations involved in selection, supply, training and use of respiratory protective equipment. It covers psycho‑physiological aspects such as comfort, thermal sensations, perceived breathing difficulty, cognitive and emotional responses, communication and tolerance to wearing RPD for task durations. It does not set protection performance values nor address hazard‑specific requirements for filtering efficiency, material compatibility or certification test methods.

Key topics and requirements

• Definitions and overview of psycho‑physiological effects relevant to RPD wear (discomfort, thermal load, perceived breathing effort, claustrophobia, anxiety).
• Factors influencing wearer acceptance: design, fit, weight, seal comfort, breathability, thermal properties and communication impact.
• Guidance for assessing comfort and tolerance in use and during different work intensities and environmental conditions.
• Recommendations on training, wearer selection and organisational measures to improve acceptance and correct use of RPD.
• Considerations for standards writers: how to incorporate human factors and usability into performance and selection standards.

Typical use and users

Used by standards developers, RPD manufacturers and designers, occupational hygienists, workplace safety and health practitioners, procurement officers, testing laboratories and training organisations. Helpful where wearer comfort, user acceptance and human‑factors considerations influence selection, certification, design iteration and workplace implementation of respiratory protective equipment.

Related standards

Part of the ISO 16976 series (human factors) and closely linked with ISO 16900 series (methods of test and test equipment) and ISO 17420 series (performance requirements). Related documents include ISO/TS 16976‑1 through ISO 16976‑8 (various human‑factors topics such as anthropometrics, thermal effects, hearing and speech, work of breathing), ISO 16900 test methods, and later national adoptions or revisions (for example updated ISO 16976‑6 editions and subsequent AS/NZS adoptions).

FAQ

Q: What is this standard?

A: It is the Australian/New Zealand technical specification SA/SNZ TS ISO 16976.6:2021 which adopts ISO guidance on psycho‑physiological effects related to wearing respiratory protective devices. It provides human‑factors guidance rather than hazard‑specific performance requirements.

Q: What does it cover?

A: It covers psycho‑physiological factors (comfort, perceived breathing effort, thermal sensations, psychological tolerance, communication effects), factors that influence user acceptance, and recommendations for training and organisational measures to improve correct use of RPD. It does not set protective performance limits for specific hazards.

Q: Who typically uses it?

A: Standards writers, RPD manufacturers and designers, occupational health and safety professionals, procurement and training teams, and testing/assessment bodies use this TS to inform design, selection, training and standard development where human factors matter.

Q: Is it current or superseded?

A: The 2021 SA/SNZ TS adoption is superseded at national level by later updates (national or international revisions). Organisations should check for the latest ISO or AS/NZS editions or amendments; national bodies have published updates after 2021 that replace this TS.

Q: Is it part of a series?

A: Yes — it is part of the ISO 16976 human‑factors series addressing multiple aspects of RPD interaction with users (other parts cover anthropometrics, thermal effects, work of breathing, hearing and speech, ergonomic factors, etc.). It is also used alongside the ISO 16900 test methods and the ISO 17420 performance requirements series.

Q: What are the key keywords?

A: Respiratory protective devices; psycho‑physiological effects; human factors; wearer comfort; acceptance; training; usability; RPD selection.
