This article explains what this standard covers, why it matters, and how to use it. What is EN ISO 17660-1?
EN ISO 17660-1 is an international standard titled "Welding — Welding of reinforcing steel — Part 1: Load-bearing welded joints" . en iso 17660-1 pdf
The design must minimize stress concentrations. Typical joint types covered include: (with or without backing) Lap joints Cross joints Strap joints
Direct end-to-end welding of bars (using flash welding or arc welding with backing).
Inspectors on construction sites can keep the standard accessible on tablets. This allows for immediate verification of visual inspection criteria without carrying bulky paper manuals through mud and dust. | Clause | Title | | :--- |
Before production starts, the welding procedures must be qualified through . Testing typically involves: Visual inspection of the weldment. Macroscopic examination to check internal weld quality.
This standard covers the welding of:
This standard replaced older national standards (like DIN 4099 in Germany) to harmonize welding practices across Europe and the world. Key Requirements of EN ISO 17660-1 1. Materials (Reinforcing Steel) The design must minimize stress concentrations
Ensuring the joint can withstand the design load without breaking at the weld.
