EN ISO 17660-1 does not exist in isolation. It relies on several other critical international standards, which are listed in Clause 2, "Normative references". A selection of the most important of these is shown below:
When sourcing an EN ISO 17660-1 PDF, it is highly critical to obtain it through legitimate, authorized standards institutions (such as ISO, BSI, DIN, or local national standardization bodies).
is a critical international standard for professionals in the construction and structural engineering industries. As concrete structures become more complex and demanding, the integrity of the reinforcement cage—and specifically the welding of that reinforcement—is crucial for safety and longevity.
Implementing in your projects offers several advantages:
The standard dictates strict inspection regimes, including visual inspection of all welds and non-destructive testing (NDT) to ensure the absence of cracks, excessive porosity, or lack of fusion. EN ISO 17660-1 vs. EN ISO 17660-2 It is crucial not to confuse Part 1 with Part 2: en iso 17660-1 pdf
Reinforcing bar to other steel components (such as plates, anchor channels, or structural steel profiles). Approved Welding Processes
To design reinforcement layouts and specify the correct welding details on blueprints.
Rebar possesses a unique ribbed profile and is manufactured through varying metallurgical process routes. Because of this complexity, the standard categorizes load-bearing joints into specific, tested geometric configurations:

To ensure you have the valid, current version (including any national forewords or amendments like DIN EN ISO 17660-1 or BS EN ISO 17660-1), purchase the document from authorized distributors:
EN ISO 17660-1 PDF: The Essential Guide to Load-Bearing Reinforcing Steel Welding
The standard is universally applicable to welding weldable reinforcing steel bars and stainless steel reinforcing steel in workshops and on construction sites. It applies to any welding of load-bearing joints in reinforced concrete, including structural elements in buildings and bridges. It also governs welded joints between reinforcing steel bars and other steel components, such as connection devices and insert anchors, including prefabricated assemblies.

: Connection using a third bar or plate bridging the gap.
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.
(Welding — Welding of reinforcing steel — Part 1: Load-bearing welded joints) sets out the requirements for materials, design, welding procedure approval, personnel competence, and inspection for welding load-bearing joints in reinforcing steel.
