BS 2782-5 552A-1999 《Methods of testing plastics - Optical and colour properties, weathering - Determination of changes in colour and variations in properties after exposure to daylight under glass, natural weathering or laboratory light sources》 Related products

The BS 2782-5 552A-1999 standard describes a test method for the variation of color and optical inspection properties of plastics under different lighting conditions. The standard evaluates the efflorescence performance of plastics by simulating exposure to sunlight through Glass, natural efflorescences, and laboratory Light sources. These test methods are designed to determine the color Stability and Optical inspection properties of plastics under various environment conditions to ensure their durability and Appearance conformity in practical applications.
