[Current]Eye and face protection for sports use, Part 2: Requirements for eye protectors for squash and eye protectors for racquetball and squash 57 (ISO 18527-2:2021, MOD)
AS/NZS 18527.2:2022 adopts and modifies ISO 18527 2:2021, which specifies requirements for all eye protectors intended for eye protection against hazards during playing or instructing in the sports of squash, racquetball and squash 57, as well as sports with similar hazards and no greater risks.It applies to eye protectors that incorporate prescription lenses but has no specific tests for eye protectors designed for use over spectacles.
