GB/T 1710-2008 《Comparison of resistance to light of coloured pigments of similar types》 Related products

Standard GB/T 1710-2008 "Comparison of the same type of chromadizing pigment light fastness" stipulates a general test method for comparing the light fastness of the same type of chromadizing pigment. The standard includes two exposure methods: method A, the pigment sample is exposed to natural light under Glass; method B, the pigment sample is directly exposed to artificial Light source. The principle of the test is to make a dispersion of the sample and the reference pigment, after drying, it is exposed under specified conditions, and its light fastness is assessed by comparing Color changes. The standard is suitable for evaluating the color Stability of various chromadizing pigments in different lighting environments, providing a scientific basis for pigment application and product quality control.
