Why should you use BS EN 3902 - Washers for rivet assemblies?
A washer is a thin plate (typically disk-shaped, but sometimes square) with a hole (typically in the middle) that is normally used to distribute the load of a threaded fastener, such as a bolt or nut. Other uses are as a spacer, spring (Belleville washer, wave washer), wear pad, preload indicating device, locking device, and to reduce vibration (rubber washer).
The rivet assembly is inserted into a hole drilled through the parts to be joined and a specially designed tool is used to draw the mandrel through the rivet. Anodizing is an electrochemical process that creates a protective coating on the surface of a piece of metal, typically aluminum. The anodized aluminum finish provides corrosion-resistance and allows for improved durability from the protective anodized aluminum.
BS EN 3902 specifies the characteristics of washers for rivet assemblies, in anodized aluminium alloy. This can benefit you as this information is used in various aerospace applications. This can help you increase safety in operations.
