Eye and face protection. Test methods - Geometrical optical properties Ingestion-build-78747 Coexistence management according to IEC1 Scope This document specifies 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. This document does not apply to any eye and face protection product requirement standards for which other test methods are specified. Other test methods can be used provided they have been shown to be equivalent and
