Scope
This Part of EN 13523 sepcifies procedures for determining the instrumental colour difference (CIELAB) of an organic coating on a coil coated metal.
Establishing a standard as well as the magnitude of an acceptable colour difference are not covered by this method.
Two appropriate methods are given in this part of EN 13523:
a) instrumental colour difference measurement using a tristimulus colorimeter;
b) instrumental colour difference measurement using a spectrophotometer or equivalent.
Excluded from this method are specimens producing fluorescence, showing significant metamerism, and which are multi-coloured, pearlescent or metallic.
In order to determine whether metamerism is present, the metamerism index is determined (see EN 13523-15) and/or a visual examination (see the document in preparation, WI 00139156, Part 22 of this Standard) is performed with different artificial light sources.

Subjects

Colours and measurement of light (17.180.20) Organic coatings (25.220.60)
