Pertains to the optical performance of untreated or coated materials supplied in plane sheet or strip form for use as a plane or formed reflector as well as preformed reflectors both as originally produced and after prescribed tests to determine probable maintained performance in service.

This European standard is applicable to the optical performance of untreated or coated materials supplied in plane sheet or strip form for use as a plane or formed reflector as well as preformed reflectors both as originally produced and after prescribed tests to determine probable maintained performance in service. This includes: a) untreated base materials, including: 1) aluminium, 2) steel, 3) plastic, 4) glass. b) surface treated materials, including: 1) polished materials, 2) anodised materials, 3) vacuum metallised materials, 4) painted materials, 5) multilayer systems. This European Standard is not applicable to fluorescent materials.
