Building inspectors and third-party auditors require proof of compliance with the latest active version of the standard.

Before this standard, welding reinforcing steel (rebar) was a complex challenge because rebar is often ribbed and produced through various metallurgical routes. EN ISO 17660-1 was created to provide a universal technical framework for load-bearing welded joints EN ISO 17660-1 was created to provide a
Not all rebar can be welded. The standard specifies which steel grades (e.g., B500B, B500C according to EN 10080) are permissible. Weld the wrong grade, and your joint becomes brittle. Need a quick reference
Need a quick reference? Remember: EN ISO 17660-1 = welding rebar for load-bearing structures. Part 2 covers non-load-bearing welded reinforcement. Always check the latest edition—as of 2025, the 2006 version remains current, but verify with your national standards body.
To stay compliant with EN ISO 17660-1, manufacturing shops and construction sites must implement a structured quality control workflow:
The standard ensures quality through several technical pillars: 1. Materials and Welding Processes
