BS EN 13523‑7 is one of the parts of a multi-series standard specifies the procedure for determining the resistance to cracking of an organic coating on a metallic substrate when bent through 135° to 180°. The degree of adhesion can also be evaluated.
Both folding and mandrel methods are considered. The folding method is more often used for practical purposes but where more precise determinations are required, the mandrel method is the preferred method.
BS EN 13523‑7 on coil coated metals is applicable to:
BS EN 13523-7 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 13523-7 aids in the improvement of the quality of organic coating on coil coated metals.
