The work of preparing International Standards is normally car
24、ried 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.
25、 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 Interna
26、tional 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
27、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 15630-1 was prepared by Technical Committee ISO/TC 17, Steel, Subcommittee SC 16, Steels for the reinforcement and prestressing of concrete. This second
28、 edition cancels and replaces the first edition (ISO 15630-1:2002), 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

In that context, the existing International Standards for tes
30、ting 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.

45、nless otherwise agreed or specified in the product standard, the test piece shall be taken from the bar, wire rod or wire in the as-delivered condition. In the case of a test piece taken from coil, the test piece shall be straightened prior to any tests by a bend operation with a minimum amount of p
46、lastic deformation. NOTE The straightness of the test piece is critical for the tensile test and the fatigue test. The means of straightening the test piece (manual, machine) shall be indicated in the test report1). For the determination of the mechanical properties in the tensile test and the fatig
47、ue test, the test piece may be artificially aged (after straightening if applicable), depending on the requirements of the product standard. If the product standard does not specify the ageing treatment, the following conditions should be applied: heating the test piece to 100 C, maintaining at this
48、 temperature 10 C for a period of 1 h150+min and then cooling in still air to ambient temperature. If an ageing treatment is applied to the test piece, the conditions of the ageing treatment shall be stated in the test report. 5 Tensile test 5.1 Test piece In addition to the general provisions given
49、 in Clause 4, the free length of the test piece shall be sufficient for the determination of the percentage elongations in accordance with 5.3. If the percentage elongation after fracture (A) is determined manually, the test piece shall be marked in accordance with ISO 6892-1. If the percentage total elongation at maximum force (Agt) is determined by the manual method, equidistant marks shall be made on the free length of the test piece (see ISO 6892-1). The distance between the
