The standard does not cover every type of welding. It explicitly excludes factory production of welding fabric (e.g., standard reinforcement meshes) and lattice girders that are manufactured using multiple spot welding machines or multiple projection welding machines. Additionally, the requirements of this standard are . It does not cover applications where the welds would be subject to significant dynamic or impact loading (such as in seismic zones) unless specifically considered.
Enterprise engineering databases (like IHS Markit, SAI Global, or ASTM Compass) provide licensed PDF access for corporate engineering teams.
It applies to both factory-produced and site-welded steel bars (typically grade 400 or higher) used in concrete reinforcement.
Before production begins, a must be prepared in accordance with EN ISO 17660-1. This document defines how the weld should be created. 2. Welding Procedure Qualification Record (WPQR) en iso 17660-1 pdf
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
Before production, a must be created. This document details: Base material types. Filler materials. Welding parameters (current, voltage, speed). Joint design (butt, lap, cross joints). 4. Welding Procedure Qualification
: By strictly following the standard, the team avoids the risk of "brittle failure"—where a joint looks solid but snaps under pressure. The tower’s foundation is certified as safe, auditable, and capable of supporting its intended load for decades. Why the Standard Matters The standard does not cover every type of welding
: It covers standard ribbed bars used in reinforced concrete. 2. Welding Personnel
In the digital age, the is the gold standard format. Here’s why professionals hunt for the official PDF rather than relying on second-hand summaries:
EN ISO 17660-1:2006 is an essential standard governing load-bearing welded joints in reinforcing steel, ensuring safety and reliability in concrete construction. It is currently under revision, with a new draft expected soon. For any professional involved in this field, obtaining the official PDF through authorized vendors is a necessary and critical step to ensure compliance and best practice. It does not cover applications where the welds
By adhering to the guidelines set out in the , manufacturers and contractors can ensure high-quality, durable joints that are essential for modern infrastructure. Share public link
Because ISO standards are protected by copyright, downloading a free EN ISO 17660-1 PDF from unauthorized file-sharing websites is illegal and poses a risk of using outdated or corrupted data.
