GB/T 1747.2-2008 "Paints and varnishes - Determination of pigment content - Part 2: Ashing method" specifies the method for determining pigment content in paints and varnishes using the ashing method, which is applicable to products that do not contain volatile metal compounds. The method involves removing organic components such as the binder through high-temperature ashing, and calculating the pigment content by weighing the residual pigment mass. Testing requires instruments such as a muffle furnace, analytical balance, porcelain crucible, and desiccator, providing accurate data for the verification of paint formulations and quality control.
