ISO/TS 20141:2022

Overview

ISO/TS 20141:2022 - Personal safety - Personal protective equipment - Guidelines on compatibility testing of PPE provides practical guidance for evaluating how multiple pieces of personal protective equipment (PPE) perform together as an ensemble. The technical specification explains compatibility concepts where workers must wear more than one PPE item to control multiple hazards and offers suggested test procedures to detect interactions that reduce protection or restrict safe operations. It also covers interactions with non‑PPE items (for example cap lamps, instruments and tools) and effects on integrated sensors and electronic devices.

Key topics and requirements

• Definition of compatibility for PPE ensembles and principles for evaluating combined performance.
• Examples of interactions between PPE items, between PPE and the operating environment, and between PPE and electronic/integrated sensors.
• Suggested test procedures and observational methods to assess functional impact, including donning/doffing, head movements (bending, nodding, shaking), torso flexing, arm movements, walking (flat, stairs, ladders), crawling, handling tools, reading instruments, and operation of electronic safety equipment.
• Guidance on test selection: how to choose ensemble components and representative test persons, report content, and acceptance criteria.
• Special considerations: thermal, chemical and mechanical protection compatibility; multiple‑hazard scenarios; environmental effects.
• Statistical and experimental design guidance (informative Annex A) for practical performance testing and for setting defensible acceptance criteria.
• Intended use for standard writers: guidance for authors of performance requirements and test methods for PPE.

Practical applications

• Designing and validating PPE ensembles for multi‑hazard workplaces (construction, manufacturing, emergency response, utilities).
• Verifying that combining PPE items (e.g., helmets, eye/face protection, hearing protection, respirators, gloves, garments) does not reduce protection or impede tasks.
• Assessing compatibility with wearable electronic sensors, communication devices and lighting equipment.
• Informing procurement decisions and employer PPE selection to ensure safe, comfortable, and functional ensembles.
• Supporting regulators and certification bodies in developing performance test methods addressing ensemble interactions.

Who should use ISO/TS 20141:2022

• PPE manufacturers and designers (to incorporate compatibility testing into product development)
• Standards writers and test laboratories (to define ensemble test methods and acceptance criteria)
• Procurement officers, safety managers and employers (to select compatible PPE for workers)
• Distributors and solution providers (to advise customers on ensemble compatibility)
