Light reflectance value (LRV) of a surface. Method of test Ingestion-build-51215

Light reflectance value (LRV) of a surface. Method of test Ingestion-build-51215BS 8493 specifies the method of test to determine the Light Reflectance Value (LRV) of different surfaces of materials. LRV is the proportion of visible light reflected by a surface compared to the sensitivity to light of the human eye. BS 8493 applies to: Opaque paint coatings and paint systems, including those that cause extreme angular dependences of reflected light and those that have a surface texture of <2 mm Opaque coverings including those
