This document specifies photometric methods of test for comparing in the visible spectrum:
a) the tinting strength of two similar coloured pigments dispersed in an alkyd resin without a drier;
b) the scattering power of two white pigments of the same type dispersed in an alkyd resin without a drier.
This document does not apply to the comparison of coloured pigments that on reduction differ greatly in colour.
