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 second edition cancels and replaces the first edition (ISO 10144:1991), which has been technically

revised.
The following changes have been made:
— the references to ISO/IEC standards have been updated;
— the scheme stages have been aligned with modern certification criteria;
— the sampling criteria have been clarified.

Any feedback or questions on this document should be directed to the user’s national standards body. A

4 Initial product and process evaluation
4.1 General

A signed certification agreement should be concluded before commencing the certification process,

covering the product range requiring certification.
4.2 Purpose

The purpose of product evaluation is to ensure that the manufacturer has the capability and resources

to produce reinforcing steels in accordance with the requirements specified in the product standards.

4.3 Organization

The certification body provides assessment and impartial third-party attestation that the specified

requirements have been achieved. Product certification shall be conducted by certification bodies

meeting the requirements of ISO/IEC 17065.
4.4 Procedure
4.4.1 General
Evaluation consists of the following stages:
— assessment of conditions for production (4.4.2);
— sampling and testing of specimens (4.4.3);
— calculation and verification of the long-term quality level (4.4.5).
If satisfactory results are not achieved in one stage, all the stage
