ISO 16900-7:2020

Overview - ISO 16900-7:2020 in brief

ISO 16900-7:2020, "Respiratory protective devices - Methods of test and test equipment - Part 7: Practical performance test methods", specifies subjective, wearer-based practical performance tests for respiratory protective devices (RPD). These tests simulate real-world use to assess properties, characteristics and functions of RPDs that cannot be fully evaluated by laboratory measurements alone. The standard is a supplement to RPD performance standards and is part of the wider ISO 16900 series.

Key topics and technical requirements

• Purpose and scope: Subjective assessment of RPD performance when worn by test subjects in simulated practical tasks.
• Prerequisites: Practical tests are performed only after satisfactory laboratory performance per relevant performance standards.
• Test subjects: Selection and anthropometric allocation follow ISO/TS 16976-2 (bivariate face panels). Subjects must be trained, medically appropriate under national rules, and able to complete activities unaided.
• Test conditions: Ambient conditions (temperature, humidity, illuminance, background noise) must be measured and recorded. Default ambient range is typically 16 °C to 32 °C and (50 ± 30) % RH unless otherwise specified.
• Test activities: A defined sequence (Annex A) of simulated tasks - e.g., walking, crawling, stair climbing, manual handling tasks, handling of materials, vision and auditory tasks - is performed continuously without removing the RPD unless permitted. Annex B covers additional optional tests.
• Subjective assessment: Test subjects wear the device, follow manufacturer instructions, don the correct size, perform pre-use checks and then provide feedback on comfort, fit, usability and information clarity. Observers may add comments.
• Reporting requirements: Reports must include test environmental conditions, completion status of tasks, reasons for non-completion, results of Annex B tests, counts from specified tasks (e.g., activity 8), whether manufacturer instructions were understandable, and other relevant observations.

Practical applications and users

• Who uses it: PPE manufacturers, conformity assessment and test laboratories, certification bodies, occupational health and safety professionals, procurement specifiers, and R&D teams.
• Why it matters: ISO 16900-7 provides a structured method to validate ergonomics, usability, compatibility with other PPE, and user instructions under realistic use conditions - essential for product design validation, compliance documentation and practical user-safety evaluation.

Related standards

• ISO 16972 - Terms, definitions and symbols for RPD
• ISO/TS 16976-2 - Human factors: anthropometrics and bivariate face panels
• Other parts of the ISO 16900 series (performance and measurement methods)

This standard is a practical, user-focused complement to laboratory test methods and is critical when assessing real-world performance and user acceptance of respiratory protective devices.
