This standard specifies a method for determining the daylight reflection ratio of Paints and varnish to evaluate the reflection performance of coatings under sunlight exposure. By measuring coatings' reflectance to daylight, the standard helps to determine the ability of coatings to reflect light radiation in everyday environments, a performance that is particularly important for paint products in areas such as construction, transportation, etc. Measurement conditions, equipment requirements, sample preparation and testing steps are described in detail, and guidance is provided for data calculation and evaluation of results. This method helps to optimize the energy efficiency performance of coatings, especially in reducing heat island effects and improving building energy efficiency. It is suitable for coating manufacturers, mass testing institutions and environmental research fields, and helps to improve the environmental performance and energy efficiency of coatings.
