This standard is equivalent to ISO 787/17-1973, which specifies a general method for comparing the lighting power of white pigments. The standard is divided into two methods, A method and B method, which are suitable for different testing needs. Method A is used for the rapid test of a single pigment, and method B is used for the comparison of multiple samples. The test involves the preparation and application of blue paste, which ensures the accurate evaluation of lighting power. This standard helps to unify the lighting power test of white pigments and improve the standardization of the experiment.
