GB/T 33329-2016 "Pigments and Extenders - Determination of Loss on Ignition and Residue on Ignition" is applicable to the testing of relevant indicators for pigments and extenders. The method involves igniting the sample in a muffle furnace at a specified temperature, accurately weighing the sample mass before and after ignition using an analytical balance, and calculating the loss on ignition and residue content. It specifies requirements for ignition temperature, holding time, and sample quantity. Parallel test results must comply with precision regulations to ensure the accuracy of the determination results.
