DIN 25201-2 Railway Vehicles and Components - Bolted Connections - Mechanical Applications

EUROLAB, with its state-of-the-art accredited laboratories and expert team, offers precise and rapid testing services within the scope of DIN 25201-2 test. This standard is valid for screw connections made with steel screws and nuts in the rail vehicle industry according to DIN EN ISO 898-1 and DIN EN 20898-2.

It can also be applied to connections made with screws and nuts of steel groups A3506 and A1 according to DIN EN ISO 3506-2 and DIN EN ISO 2-4, with material-related restrictions. It should support the designer in the basic selection of screw connections and provide him with an understanding of the system and terms.

In principle, the standard is not exempt from experimental or numerical (FEM - Finite Element Method, BEM - Boundary Element Method) investigations for verification of results. This is especially true for critical links.

In principle, fasteners conforming to DIN 25200 and DIN 25201-4 should be used. shims should be designed to be limited to the minimum required. Screws and nuts must belong to the same strength class or be made of the same material.

For screw connections with dynamic or static load to function, a certain preload force must be present. The required preload force is achieved using screws and nuts of sufficiently high strength, tightened using the specified screwing class with the calculated or specified control and control value.
