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 15630-3 was prepared by Technical Committee ISO/TC 17, Steel, Subcommittee SC 16, Steels for the
reinforcement and prestressing of concrete.
This second edition cancels and replaces the first edition (ISO 15630-3:2002), which has been technically
revised.
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 the testing of metals, in general, as they are applicable.
Complementary provisions have been given if needed.
