AS/NZS ISO 18526.1:2021
Eye and face protection - Test methods, Method 1: Geometrical optical properties
Standard identically adopts ISO 18526-1:2020, specifying the reference test methods for determining the spherical, cylindrical, and prismatic refractive power properties of unmounted and mounted plano lenses (non-corrective lenses) for eye and face protectors. Does not apply to any eye and face protection product requirement standards for which other test methods are specified. KEYWORDS: Eye; Face; Protection; Plano lenses; Geometric
