Overview
ISO 12311:2023 - "Personal protective equipment - Test methods for sunglasses and related eyewear" - specifies reference test methods for determining the mechanical and environmental properties of sunglasses and related eyewear referenced in ISO 12312 (all parts). It applies to all sunglasses and related eyewear and allows use of other test methods when equivalence can be demonstrated. The second edition updates the scope of retained methods and aligns with related head‑form test methods (ISO 18526 series).
Key topics and technical requirements
Practical applications and who uses it
