BS EN 13523-22 specifies the procedure for determining the difference in the colour of an organic coating on a metallic substrate by visual comparison against a standard using either diffuse natural daylight or artificial daylight in a standard booth.
BS EN 13523-22 guidance specifies that two colour specimens will match in daylight but not under another light source. This phenomenon is known as metamerism standardization of such visual comparisons, by light sources, illuminating and viewing geometry and specimen size, provides for improved uniformity of results. This practice is essential for critical colour matching and is highly recommended for colour inspections.
NOTE Results might differ between natural and artificial daylight.
