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 is not appropriate for the comparison of coloured pigments that on reduction differ greatly in colour.

This document specifies a general method of test for determining the oil absorption value of a sample of pigment or extender. The oil absorption value is usually required to be compared with the value determined at the same time on an agreed sample of the product.
