DIN 25201-1 Railway Vehicles and Components - Bolted Connections - Classification of Bolted Connections

EUROLAB, with its state-of-the-art accredited laboratories and expert team, offers precise and rapid testing services within the scope of DIN 25201-1 test. This standard applies to the selection and use of screw connections in the rail vehicle industry. It is aimed to support the designer in the basic selection of screw connections and to ensure that he understands the necessary systems 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 recommended for critical links.

All parts of this standard must be taken into account when designing a bolted connection. The screw connection includes the components to be connected as well as the fasteners.

This part of the DIN 25201 standard specifies the risk classes, stress states and categories of screw connections and provides an overview of the resulting relationships.

The risk potential in case of screw connection failure is defined by three risk classes. Different requirements for the dimensioning, assembly and documentation of the screw connection and the tools to be used during assembly can be derived from the risk classes.
