What is BS EN 13523‑3 about?

BS EN 13523‑3 is one of the parts of a multi-series procedures for determining the instrumental colour difference (CIELAB) of an organic coating on a metallic substrate compared to another one used as a reference and the metamerism depending on the illuminant.

BS EN 13523‑3 provides two methods to determine instrumental colour difference:

Measurement using a tristimulus colourimeter
Measurement using a spectrophotometer or equivalent

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

Who is BS EN 13523‑3 for?

BS EN 135233 on coil coated metals is applicable to:

Coil coating chemical industries.
Sheet metal industry
Furniture industry
Steel and aluminium industries
Automotive, mechanical Industries

Why should you use BS EN 13523‑3?

BS EN 13523-3 provides test guidelines for organic coating on coil coated metals, which are used for design flexibility, corrosion resistance, and weathering resistance. Adherence to these guidelines ensures increased durability of metals.

By offering test procedure guidelines, BS EN 13523-3 aids in the improvement of the quality of organic coating on coil coated metals.
