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.

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 15630-1:2010), which has been

technically revised. Changes have been introduced in the Introduction, Clause 2, Clause 3, Clause 4,

Clause 5 (only the title), 5.3, 6.3, 8.3, 8.4.5, 10.3.1.1, 10.3.1.2, 10.3.3 and 11.3.2 and Figure 6. A new

Clause 13 has been added for “specialized” tests. The Bibliography has been updated and the dated

references have been replaced by undated references.

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 (see Clauses 5 to 12), as well as specialized test methods

(gathered in Clause 13) 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.
