GB/T 1725-2007 "Paints, varnishes and plastics—Determination of non-volatile matter content" specifies the method for determining the non-volatile matter content in paints, varnishes, and plastics, and is applicable to various related products. Using the drying method, the sample is heated at a specified temperature until constant mass is achieved, and the mass fraction of non-volatile matter is calculated by weighing. The test requires instruments such as an analytical balance, a constant-temperature drying oven, and weighing dishes. The operation is simple and versatile, providing fundamental data for product composition analysis and quality control.
