The standard consists of 5 sections;

EN 15085-1 General
EN 15085-2 Quality specifications and certification of welding manufacturer
EN 15085-3 Design features
EN 15085-4 Manufacturing rules
EN 15085-5 Inspection, testing and documentation


In Part 2 of the Standard; EN 15085-2 Certification / Quality Requirements of Businesses Performing Welded Manufacturing. Companies are certified under 4 certification levels. The certification level is determined according to the production capacities and performance classes of the companies (CPA-CPD).

CL1 - Railway vehicles / vehicle parts with high-quality welded seams. All vehicle manufacture is covered. All steps from CL 2 to CL 4 are also included.

CL2 - Except main components, boarding gates, roof equipment, etc. A lower class quality level was determined for the production of parts.

CL3 - Includes production of simple equipment parts for the production of railway vehicles. This certification level includes manufacturing with a Quality Level CPD.

CL4 - For enterprises that do not manufacture welded, but design, buy, install or operate railway vehicles and components.


Depending on each class, quality classes, equipment and personnel qualification and control / acceptance criteria must be determined by the firm. Certification according to EN 15085 can also be carried out with SS-EN ISO 3834. If the manufacturer has an approved system in accordance with ISO 3834, periodic revisions may be coordinated.
