Alternatively, is there an updated version of this standard (possibly EN ISO 17660-1:2022)? Any clarification would be appreciated.
The standard is divided into two distinct parts based on the structural function of the weld:
The EN ISO 17660-1 standard is the definitive international guideline for the welding of reinforcing steel. Specifically, Part 1 focuses on load-bearing welded joints, ensuring that structural connections in reinforced concrete meet rigorous safety and performance criteria. For engineers, contractors, and quality assurance professionals, understanding the technical nuances of this document is essential for maintaining structural integrity. Scope and Application
If you are looking for specific procedures for your project, I can help explain the differences between testing methods or the types of welded joints covered. Share public link
The differences between and Part 2 (Non-load-bearing) . Common non-destructive testing (NDT) methods for rebar. en iso 17660-1 pdf
Price range: Typically €100 – €180 for a single-user PDF.
Refers to non-load-bearing joints (e.g., for positioning).
Many construction contracts and local building regulations in Europe and globally require compliance with EN ISO 17660-1.
The standard details requirements across several key areas: Alternatively, is there an updated version of this
A vital section of the standard addresses the verification of weld integrity. Because surface ribs prevent standard non-destructive testing (NDT) methods like ultrasonic inspection from being fully reliable, EN ISO 17660-1 heavily relies on destructive testing. ISO 17660-2 - iTeh Standards
: Connection using a third bar or plate bridging the gap.
Overlapping bars perpendicular to each other, welded at the intersection.
To stay compliant with EN ISO 17660-1, manufacturing shops and construction sites must implement a structured quality control workflow: Specifically, Part 1 focuses on load-bearing welded joints,
is an international standard that specifies requirements for the welding of weldable reinforcing steel and stainless reinforcing steel in load-bearing joints
Welding reinforcing steel is a critical process in modern civil engineering and concrete construction. To ensure the safety, structural integrity, and durability of reinforced concrete structures, specific technical rules must be followed. This is where the international standard comes into play.
Without the official PDF on your tablet or laptop at the worksite, you cannot prove compliance when an inspector arrives.
EN ISO 17660-1 outlines requirements for various joint configurations, including:
The current edition (EN ISO 17660-1:2006) has been the benchmark for reinforcing steel welding for nearly two decades, but it is important to note that a significant update is on the horizon. Draft versions such as ISO/DIS 17660-1:2026 and prEN ISO 17660-1:2026 are currently under development, indicating that the standard is being modernized to reflect the latest advancements in materials and welding technology.
