EN 15085-2
Railway Welded Manufacturing Qualification
The Technical Signature of Global Trust in Railway Systems: ASİS UK.
In the manufacture of railway vehicles and components, quality is not just a standard but an operational safety requirement. Under the EN 15085 standard series, ASİS UK enables manufacturers to be 'approved manufacturers' in the global railway supply chain — including the European Union and Turkey markets — and to register this status with the ASİS UK seal.
Certification Classes (CL)
EN 15085 sets requirements for welded manufacturing of railway vehicles and parts. Since welding is considered a 'special process' in this sector, design, production, and testing require strict audit.
CL 1 — High Safety
Manufacture of components requiring the highest safety, such as body structures, bogies, and critical assemblies.
CL 2 — Medium Safety
Components with medium safety criticality such as interior equipment and support structures.
CL 3 — Low Safety
Simple welded parts of low safety importance.
CL 4 — Procurement and Design
Organizations that do not perform welding but undertake the design, procurement, or sale of welded components.
