Description of BS EN 13523-3:2014 2014

This part of EN 13523 specifies procedures for determining the instrumental colour difference (CIELAB) of an organic coating on a metallic substrate.

Establishing a standard as well as the magnitude of an acceptable colour difference are not covered by this method.

Two methods are given in this part of EN 13523:

  1. instrumental colour difference measurement using a tristimulus colorimeter;

  2. instrumental colour difference measurement using a spectrophotometer or equivalent.

Care should be taken when measuring e.g.

  • textured surfaces;

  • fluorescent coatings;

  • metameric coatings;

  • multi-coloured, pearlescent, metallic or special colour effect coatings.

In order to determine whether metamerism is present, the metamerism index is determined (see EN 13523-15) and/or a visual examination (see EN 13523-22) is performed with different artificial light sources.
