Certification Procedure and Verification
The procedure for certification of welding manufacturers is described in section 15085 of EN 2-6. The manufacturer's certification body must inspect and verify the welding manufacturers to demonstrate that they meet the requirements of EN 15085 series standard. The DVS 1617 application code for subcontractors contains relevant information.
Certification Organizations
The audits are carried out by the Certification Bodies defined by EBA. EBA maintains a list of manufacturer certification bodies as defined in Germany. Certification bodies must be included in the Rail Vehicles Online Register.
Application
Certification application for the source of the rail vehicles and their components according to EN 15085-2 must be obtained from the BVA Certification.
With this application according to EN 15085-2, it defines the welding manufacturer's certification scope (welding process, dimensions and material groups according to CEN ISO / TR 15608).
In the certification procedure, the welding manufacturer should be able to present the welder qualification tests, welding procedure specification and production welding tests.
Audit
The next stage of the certification process is inspection. The technical information and qualifications of the resource coordinators in this audit should be demonstrated by the manufacturer as a requirement of the 15085 2 article 5.1.2-XNUMX.
The scope of the audit varies depending on the certification level, area of ​​application, number of welders, welding procedures, welding workshops and the scope of materials used. As part of the audits performed, the following must be verified:
• Current staff with valid Proficiency Test Certificates
• Equipment affecting production and production quality
• Welding procedure specifications, adequacy of welding procedures
• Resource Planning documentation (drawings, welding process plan, test and control plan)
• Compliance with EN ISO 3834-2, -3 and / or -4 quality requirements
Note: Welders' qualification tests and / or production welding tests can only be accepted by resource coordinators. Test certificates may only be issued by the resource coordinators defined in the manufacturer's certificate.
If the welding personnel have the relevant test certificates, the welding coordinators must verify these certificates depending on the production welding tests. If the welding staff does not have such qualification test certificates, the relevant tests may be carried out as part of the inspection and the certificates relating to these tests may be issued by the manufacturer's certification body.
In case of renewal of the present document, some welder qualification tests or production welding tests accepted by the welding coordinator should be sent to the manufacturer certification body for review. Tests not approved by the manufacturer certification body are replaced by new tests. In case of doubt about the knowledge and skills of the welder personnel, production welding tests are required and test specimens temporarily welded should be made available.
Test scopes include welding procedure specifications, evaluation table, published test certificate, announcement and source test samples related to technical information verification. The resource coordinators must keep a list of the welding staff, which shows which welder has the current qualification.
Within the scope of certification at CL 4, the conformity with the requirements of EN 15085-2 clause 5.1, substance 5.3 and EN 3834-3 must be verified.
Field Inspection
Field inspections are carried out together with welding coordinators. The above-mentioned requirements are verified during these inspections. However, regular applications for welded components and structures are verified. If relevant assembly parts and structures are not available during the initial certification process, the initial verification check is performed when production begins.
Interview with Resource Coordinators
In this informal interview, documents and provisions issued by National Security agencies may be used. Resource coordinators should demonstrate their knowledge and skills within the specific requirements of EN 15085 series standards and DVS coded guidance documents. Relevant standards should be available in the language understood by the resource coordinators. Interview questions are covered by the standards, materials and welding procedures applicable to the certificate. Non-IIW / EWF qualification resource coordinators must demonstrate their knowledge and skills under EN ISO 14371 and EN 15085-2 clause 5.1.2. In principle, depending on the level of the welding coordinator, EN ISO 14371 should show its knowledge and skills in accordance with section 6. However, the presence of adequate information should be indicated in the following areas.
