BS EN 2437 discusses Aerospace series. Aerospace is a term used to collectively refer to the atmosphere and outer space. Aerospace activity is very diverse, with a multitude of commercial, industrial, and military applications.
BS EN 2437 specifies yellow chromate conversion coating of aluminium and aluminium alloys. It shall be applicable wherever referenced.
BS EN 2437 on the yellow chromate conversion coatings for aluminium and aluminium alloys is useful for:
Chromate conversion coating is employed to impart brightness and improve the corrosion resistance of bare metal and as a substrate to provide improved paint adherence on the nonferrous surface. Yellow chromate is a chemical conversion coating that is applied over zinc plating during the surface coating process. BS EN 2437 laid out guidelines to be followed for the yellow chromate conversion coating of aluminium and aluminium alloys.
The purpose of BS EN 2437 is to increase corrosion resistance and to improve the adhesion of paints and varnishes. Type B coatings are also suitable for the repair of mechanically damaged anodic coatings. Through the guidelines mentioned in BS EN 2437, testing agencies, consumers, manufacturers, and suppliers of the product can improve the efficiency and durability of a product.
