Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 17660-2 was prepared by the European Committee for Standardization (CEN) Technical Committee
CEN/TC 121, Welding, in collaboration with Technical Committee ISO/TC 44, Welding and allied processes,
Subcommittee SC 10, Unification of requirements in the field of metal welding, in accordance with the
Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
ISO 17660 consists of the following parts, under the general title Welding — Welding of reinforcing steel:
⎯ Part 1: Load-bearing welded joints
⎯ Part 2: Non load-bearing welded joints
Requests for official interpretations of any aspect of this part of ISO 17660 should be directed to the
Secretariat of ISO/TC 44/SC 10 via your national standards body. A complete listing of these bodies can be

Introduction
Reinforcing steel bars are produced by a number of process routes and usually have a ribbed profile. Taking
these issues into account, it is apparent that both the welder and the welding coordinator require a specific
level of skill and job knowledge and that special procedures for quality assurance need to be adopted.

The welds shall not influence significantly the full load-bearing capacity and ductility of the bars, and the
welding procedure may not cause embrittlement of the material.
NOTE The purpose of a non load-bearing welded joint is normally only to keep the reinforcing components in their
correct places during fabrication, transport and concreting. These welds are often referred to as tack welds. The tack
weldability of reinforcing steels can be demonstrated by special tack weldability tests (see CEN/TR 15481).

ISO/DIS 17660-1, Welding — Welding of reinforcing steel — Part 1: Load bearing welded joints.
NOTE A list of European Standards (EN) conforming to these International Standards (ISO) is given in Annex ZA.
3 Terms and definitions
For the purposes of this standard, the terms and definitions given in EN 10079, prEN 10080-1 and ISO/DIS
16020 and the following apply.
3.1
load bearing welded joints
used for transmission of specified loads between reinforcing steel bars and between reinforcing steel bars and
other steel products
3.2
non-load bearing welded joints
welded joints of which the strength is not taken into account in the design of the reinforced concrete structure
NOTE The purpose of these joints is normally only to keep the reinforcing components in their correct places during
fabrication, transport and concreting. These welds are often referred to as tack welds.
3.3
