15. EN 15085-2 additions (railway welding, CL2)

For railway work, the following additions apply on top of the ISO 3834-2 core:

• Weld performance classes are assigned to joints in accordance with BS EN 15085-3 from their stress and safety category, and the certification level follows from these. The performance class designations used on IDM drawings are to be taken from the current text of BS EN 15085-3 and from the customer drawing, not from this manual. Alstom drawing 24308 specifies CP C2 and weld inspection class CT 3 against a customer-imposed CL2.
• A weld map / weld plan links each joint to its WPS, welder and inspection requirement.
• Manufacturing and inspection documentation is retained per EN 15085-5, including weld history records.
• The RWC holds competence appropriate to CL2 (see Section 7); welder and operator qualifications are current per EN ISO 9606 / EN ISO 14732.
• Certification is by TWI Certification, appointed across BS EN ISO 3834-2, BS EN 1090-1 and BS EN 15085-2 so that the three standards are assessed as one programme.
