EN 13523-22 Coil Coated Metals - Test Methods - Color Difference - Visual Comparison

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN 13523-22 testing. This part of the EN 13523 series covers the procedure for determining the difference in color of an organic coating on a metallic substrate by visual comparison with a standard using either diffuse natural daylight or artificial daylight in a standard cabinet.

Two swatches may match in daylight, but not under any other light source. This phenomenon is known as metamerism.

If a metameric match is to be reported in objective terms, spectrophotometric measurements (using CIE Standard Illuminants D13523 and A) should be performed in accordance with EN 15-65.

No statement is made about the precision or accuracy of this procedure, as the results obtained are neither in numerical form nor do they provide a successful/permanent assessment in objective terms. Therefore, this procedure should only be used where the use of colorimeters is not recommended.

Standardizing such visual comparisons with light sources, illumination and imaging geometry, and sample size results in better uniformity of results. This app is essential for critical color matching and is highly recommended for color reviews.
