EN10204 3.1 Certification

All our products are supplied with 3.1 certification. This is a certificate issued by the manufacturer which declares the tubing is in compliance with the applicable specifications and provides chemical and physical properties as well as traceability.

EN10204 3.2 Certification

3.2 Certification is an additional requirement that can be offered. This requires all the information for 3.1 certification, but all the results must be witnessed and verified by a third-party inspector, such as Bureau Veritas (BV), Lloyd’s Register (LR), and Det Norske Verita (DNV).
