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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO’s adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www .iso
.org/iso/foreword .html.
This document was prepared by ISO/TC 17, Steel, Subcommittee SC 16, Steels for the reinforcement and
prestressing of concrete.
This third edition cancels and replaces the second edition (ISO 15630-3:2010), which has been
technically revised. Changes have been introduced in the Introduction, Clauses 1 and 2, 5.3.1, 5.3.2, 9.3,
9.4.4, 10.4.3, 11.4 (now 10.3, 10.4.4, 11.4.3, 12.4) and Figure 8. The Bibliography has been updated and
the dated references have been replaced by undated references. A new Clause 8 on the wrapping test
has been added.
A list of all parts in the ISO 15360 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www .iso .org/members .html.
This corrected version of ISO 15630-3:2019 incorporates the following corrections:

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO’s adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www .iso

This document was prepared by ISO/TC 17, Steel, Subcommittee SC 16, Steels for the reinforcement and
prestressing of concrete.
This third edition cancels and replaces the second edition (ISO 15630-3:2010), which has been
technically revised. Changes have been introduced in the Introduction, Clauses 1 and 2, 5.3.1, 5.3.2, 9.3,
9.4.4, 10.4.3, 11.4 (now 10.3, 10.4.4, 11.4.3, 12.4) and Figure 8. The Bibliography has been updated and
the dated references have been replaced by undated references. A new Clause 8 on the wrapping test
has been added.
A list of all parts in the ISO 15360 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Introduction
The aim of ISO 15630 (all parts) is to provide all relevant test methods for reinforcing and prestressing
steels in one standard series.
This document covers standard test methods, as well as specialized test methods that are not
commonly used in routine testing and that should only be considered where relevant (or specified) in
the applicable product standard.
Reference is made to International Standards on the testing of metals, in general, as they are applicable.
Complementary provisions have been given if needed.
