If you actually need a standard for non-load-bearing joints (e.g., spacers, lifting loops), you require EN ISO 17660-2, not Part 1.
The manufacturer must establish traceability: each welded joint must be identifiable to the welder, the WPS, and the batch of reinforcing steel.
The standard requires a WPS for all load-bearing joints. This document must detail:
EN ISO 17660-1 is a European Standard (EN) that is harmonized with an international standard from the International Organization for Standardization (ISO). Specifically, this standard relates to recommendations for welding of cast iron. en iso 176601 pdf
The standard defines the minimum requirements for static and fatigue strength. Following the standard ensures that the weld will not snap under the load of the concrete or the dynamic weight of traffic.
Yes – but not the full standard. Use these for reference:

Introduction In the fields of civil engineering and construction, the integrity of concrete structures relies heavily on the quality of the steel reinforcement inside them. EN ISO 17660-1 is the international standard that governs the welding of reinforcing steel. Professionals searching for an "EN ISO 17660-1 PDF" are typically looking for the specific guidelines required to ensure structural safety, welder qualification, and compliance with building regulations.
What is EN ISO 17660-1? EN ISO 17660-1, titled "Welding — Welding of reinforcing steel — Part 1: Load-bearing welded joints," is a standard developed by the International Organization for Standardization (ISO) and adopted by the European Committee for Standardization (CEN). Let us diagnose why your search may have
It specifies the requirements for the welding of reinforcing steel used in concrete structures. The standard covers various aspects of the welding process, including:
Scope and Application This standard is critical for "load-bearing" joints, meaning any weld that is responsible for transferring stress within a structure. It applies to:
It is used by structural engineers, welding coordinators, and contractors to ensure that the steel framework of a building or bridge can withstand the loads it will face during its service life.
Key Requirements Found in the Document When reading the PDF of this standard, users will find strict criteria regarding:
The Transition: EN ISO 17660 vs. EN ISO 18255 It is important for technical professionals to note the recent evolution of this standard. In 2023 and 2024, the welding of reinforcing steel standards underwent a transition. ⚠️ Avoid illegal PDF sites – they often
Accessing the PDF: Copyright and Legality Many users search for a "free PDF" download of this standard. However, ISO standards are copyrighted documents protected by international law.
Conclusion 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.
To be precise: EN ISO 17660-1:2006 is the European adoption of the international standard Welding — Welding of reinforcing steel — Part 1: Load-bearing welded joints.
Here is useful, actionable information – not the PDF itself (which is copyrighted), but how to legally obtain it and what the standard contains.
