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 3.
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 part of ISO 15630 may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 15630-1 was prepared by Technical Committee ISO/TC 17, Steel, Subcommittee SC 16, Steels for the
reinforcement and prestressing of concrete.
This part of ISO 15630, together with parts 2 and 3, cancels and replaces ISO 10065:1990, ISO 10287:1992 and
ISO 10606:1995.
ISO 15630 consists of the following parts, under the general title Steel for the reinforcement and prestressing of
concrete — Test methods:
 Part 1: Reinforcing bars, wire rod and wire
 Part 2: Welded fabric
 Part 3: Prestressing steel

Introduction
The aim of ISO 15630 is to provide all relevant test methods for reinforcing and prestressing steels in one standard.
In that context, the existing International Standards for testing these products have been revised and updated.
Some further test methods have been added.
Reference is made to International Standards on testing of metals in general as they are applicable.
Complementary provisions have been given if needed.
Test methods which do not form the subject of an existing International Standard on metal testing are fully
described in ISO 15630.

4 General provisions concerning test pieces
Unless otherwise agreed, the test piece shall be taken from the bar, wire rod or wire in the as-delivered condition.
In the case of a test piece taken from coil, the test piece shall be straightened prior to any tests by a simple bend
operation with a minimum amount of plastic deformation.
For the determination of the mechanical properties in the tensile test and the fatigue test, the test piece may be
artificially aged (after straightening if applicable) depending on the requirements of the product standard.
NOTE When the product standard does not specify any ageing treatment, the following conditions may be applied: Heating
+ 15
the test piece to 100 °C, maintaining at this temperature ± 10 °C for a period of 1 hour min and then free cooling in still air
0
to ambient temperature.
When an ageing treatment is applied to the test piece, the conditions of the ageing treatment shall be stated in the
test report.
5 Tensile test
5.1 Test piece
In addition to the general provisions given in clause 4, the free length of the test piece shall be sufficient for the
determination of the percentage elongations in accordance with 5.3.
When percentage elongation after fracture (A) is determined, the test piece shall be marked according to clause 8
of ISO 6892:1998.
When percentage total elongation at maximum force (A ) is determined by the manual method, equidistant marks
gt
shall be made on the free length of the test piece (see annex H of ISO 6892:1998). The distance between the
marks shall be 20 mm, 10 mm or 5 mm, depending on bar, wire rod or wire diameter.
