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 15630-2 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 1 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 SIST EN ISO 15630-2:2003



ISO 15630-2:2002(E) © ISO 2002 – All rights reserved v 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. SIST EN ISO 15630-2:2003
