It defines how welders must be tested—using visual inspection, bend tests, or macro-sections. No EN ISO 17660-1, no valid welder qualification.
A major section of the standard deals with who is allowed to weld. It mandates that welders must be qualified according to EN ISO 9606-1. The PDF outlines the specific tests a welder must pass to be certified for different rebar diameters and welding positions.
In the world of structural engineering and construction, the welding of reinforcing steel (rebar) is a critical process. A failure in a welded splice can compromise the structural integrity of concrete, leading to catastrophic results. This is where EN ISO 17660-1 serves as the industry benchmark. en iso 17660-1 pdf

Price range: Typically €100 – €180 for a single-user PDF.
The acceptance criteria are strict: maximum undercut depth, number of pores per inch of weld, and allowable spatter. The PDF gives you the numbers, not just advice. Price range: Typically €100 – €180 for a

Prices typically range from €80 to €150 (approx. $85–$160 USD) for a single-user PDF. Many national bodies offer a “read-only” online version for a lower fee.
Unofficial PDFs are often old versions. ISO standards are periodically reviewed and amended. The current version (as of 2025) includes updated heat-input limits and new classifications for thermomechanically treated bars. An old PDF could lead to rejected weld procedures.
