JIS K5101-15-2-2004 "Pigment test methods, Part 15: heating loss. Section 2 combustion residue", standardizes the determination method of pigment combustion residue. The standard specifies the operation process and temperature, time and other key conditions of sample weighing, high temperature burning, and specifies the weighing and calculation method of the residue after burning. It is used to accurately determine the residual material content of pigment after heating combustion, and provides a technical basis for evaluating pigment purity and mass Stability.
