General methods of test for pigments and extenders — Part 24: Photometric methods for determining the relative tinting strength of coloured pigments and the relative scattering power of white pigments

Méthodes générales d’essai des pigments et matières de charge — Partie 24: Méthodes photométriques pour la détermination du pouvoir colorant relatif des pigments colorés et du pouvoir diffusant relatif des pigments blancs

Abstract / scope

This document specifies photometric methods of test for comparing in the visible spectrum:

  1. the tinting strength of two similar coloured pigments dispersed in an alkyd resin without a drier;
  2. 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.
