GB/T 20503-2006 Anodizing of aluminium and its alloys—Measurement of specular reflectance and specular gloss at angles of 20°,45°,60°or 85°
Abstract
This standard specifies the methods for measuring the specular reflectance and specular gloss of aluminum and aluminum alloy anodized film flat samples when using geometric angles of 20° (Method A), 45° (Method B), 60° (Method C), and 85° (Method D), as well as the method of measuring specular reflectance using a narrow receiving angle of 45° (Method E). This standard is primarily applicable to transparent anodized film surfaces and can also be used for colored anodized films, but only for comparisons between similar colors.
