Many years of experience with DVS ZERT

This standard is the basis for the welding of metallic materials in the manufacture and repair of rail vehicles and parts. It specifies the quality requirements for the construction of new rail vehicles and their repair.

The certification according to DIN EN 15085-2 is relevant for manufacturers who weld on rail vehicles, rail vehicle parts and components. The standard is also aimed at design offices that design rail vehicles or rail vehicle parts as well as companies that purchase and assemble welded components or purchase and distribute them. The EN 15085 series standard is a recognised rule of technology throughout Europe and the world.

DVS ZERT, as an accredited certification body recognised by the ECWRV (European Committee for Welding of Railway Vehicles), audits your welding company for compliance with and implementation of the standard requirements of DIN EN 15085-2 at the corresponding certification level. After the successfully completed audit, we issue the certificate for the manufacture of railway vehicles and parts, for the construction as well as the purchase and assembly of welded components. For welding companies that carry out repair services on rail vehicles, the additional requirements according to EN 15085-6 must also be fulfilled.
