What is BS EN 3903 - Laminated washers about?

BS EN 3903 is a European standard on aerospace series which covers laminated washers in corrosion resisting steel.

BS EN 3903 specifies the characteristics of laminated washers, in corrosion-resisting steel, for maximum operating temperature 120 °C, for aerospace applications.

Who is BS EN 3903 - Laminated washers for?

BS EN 3903 on laminated washers is useful for:

Aerospace parts manufacturers
Laminated washer manufacturers

Why should you use BS EN 3903 - Laminated washers?

A laminated flat washer or shim is a flat disc with a centrally located hole. Laminated round flat washers or shims are unique in that the thickness can be adjusted by peeling off a layer to fit a variable height requirement. It, also, provides a bearing surface to minimize surface wear like a typical flat washer. They also evenly distribute a fastener’s load to minimize surface deformation from fastener tightening or can cover large clearance holes.

Steel has a certain resistance against corrosion. This so-called passivity is due to a thin and invisible layer of oxides being formed on the surface. This process takes place through a reaction between the metal and the oxygen in the surrounding environment.

With the help of BS EN 3903 which specifies the characteristics of laminated washers, in corrosion-resisting steel, for maximum operating temperature 120 °C, you can benefit from the use of the information in various aerospace applications. This can help you increase safety in operations.
