The EN ISO 17660-1 standard mandates strict examination to ensure compliance:
Focuses on load-bearing joints . These are connections where the weld is calculated to carry structural design loads (e.g., splicing bars to extend their length).
It applies to both factory workshops and on-site welding of weldable reinforcing steel and stainless reinforcing steel. Scope and Key Requirements en iso 17660-1 pdf
Detailed guidance is provided for butt, lap, strap, and cross joints to ensure they can achieve full load-bearing capacity. Personnel Qualification:
When working with an official EN ISO 17660-1 PDF document, users will find that the core text is divided into several strict quality assurance pillars. 1. Material Weldability The EN ISO 17660-1 standard mandates strict examination
) typically ranging up to 50 mm, or as specified by local building regulations.
What specific (e.g., MMA 111, MAG 135) you intend to use? The diameter and steel grade of the reinforcing bars? Scope and Key Requirements Detailed guidance is provided
Only welders qualified specifically for reinforcing steel (certified according to or relevant EN standards) are permitted to produce load-bearing joints. 4. Weld Type and Diameter Coverage Butt Joint: Generally applies to bar diameters from Cross Joint: Typically covers for load-bearing applications.
This is the most referenced section by site engineers. The standard provides specific "Acceptance Criteria" for visual defects. It tells you exactly what is allowed and what is a reject:
