General methods of test for pigments and extenders - Part 15: Comparison of resistance to light of coloured pigments of similar types (ISO 787-15:1986); German version EN ISO 787-15:1995
The document specifies a general method of test for comparing the resistance to light of samples of similar types of coloured pigments (agreed reference pigment and test sample). Two methods of exposure are described. In method A, the material is exposed under glass to natural light. In method B, the material is exposed directly to artificial light.
