Unlike many structural steel standards, EN ISO 17660-1 emphasizes . Samples must be taken directly from the ongoing production line or site at specified intervals (e.g., every specified number of welds) and subjected to destructive tensile testing to prove that consistency is maintained. Summary of Key Compliance Checklist
For structural engineers, welding coordinators, and quality control managers, accessing the official via authorized platforms like the ANSI Webstore or the BSI Knowledge Platform is critical to maintaining regulatory compliance and structural integrity. Scope and Application of Part 1 The EN ISO 17660 series is split into two distinct parts:
Valid WPS available at the welding station; supporting WPQR.
EN ISO 17660-1 remains a foundational reference for the welding of reinforcing steel. It ensures that the skeleton of our infrastructure—concrete reinforcement—is fused together with safety and precision. For any professional in the construction industry, obtaining the official, current version of this document (or its successor, EN ISO 18255) is a necessary step in maintaining quality assurance and regulatory compliance.

Implementing the workflows detailed in the EN ISO 17660-1 document guarantees:
The standard is built upon several fundamental requirements that govern the entire welding process to ensure safety and quality. Unlike many structural steel standards, EN ISO 17660-1

Post-weld evaluation is critical to confirm the load-bearing capacity of the joints. EN ISO 17660-1 defines both destructive and non-destructive testing (NDT) methods.
Post-welding inspection ensures that the executed joints match the qualified standards. EN ISO 17660-1 outlines both the frequency of testing and acceptable defect limits. Non-Destructive Testing (NDT)
The standard does not simply recommend a WPS; it requires that all welding for load-bearing joints must be performed in accordance with a qualified WPS. The WPS must be based on preliminary welding procedure tests as outlined in the standard’s clauses 11 and 12. This ensures that the planned welding method is capable of producing welds that meet the specified quality and mechanical requirements. Scope and Application of Part 1 The EN

The standard mandates the appointment of a (in accordance with ISO 14731). The coordinator's technical knowledge level (Basic, Specific, or Comprehensive) depends on the complexity of the welding operations and the diameter of the reinforcing bars being used. Testing and Inspection (NDT and Destructive)
The primary purpose of EN ISO 17660-1 is to guarantee that load-bearing welded joints in reinforced concrete structures maintain structural integrity under static loads. Because reinforcing bars (rebar) feature unique ribbed profiles and varied metallurgical processing paths, standard structural steel welding methods are insufficient.
