12、 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 represente
13、d 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 draf
14、ted in accordance with the rules given in the ISO/IEC Directives, Part 2. 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 Sta
15、ndard 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 document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 18265 was prepared
16、by Technical Committee ISO/TC 164, Mechanical testing of metals, Subcommittee SC 3, Hardness testing.

18、erified and calibrated hardness testing machines. Statistically reliable information cannot be given on the uncertainty of these values because the test conditions were not reproducible, and the number of results used to calculate the mean hardness values is not known. The conversion values in Table
19、 A.1 are in accordance with the information presented in IC No. 3 (1980) and IC No. 4 (1982) of the European Coal and Steel Community, as well as in ISO 4964:1984 and ISO/TR 10108:1989. Annexes C, D and E contain in a revised format the extensive results on the conversion of hardness values presente
20、d in TGL 43212/02 to 43212/04, standards published by the former East German standards body, the Amt fr Standardisierung, Mewesen und Warenprfung (ASMW). The values presented in Annex B had also been determined by the ASMW, but were published in a report of the Physikalisch- Technische Bundesanstalt
21、 (PTB) 1, the German national institute for science and technology, not in a TGL standard. The converted hardness values in the above-mentioned TGL standards were obtained in statistically reliable hardness and tensile tests. The hardness tests were performed using ASMW normal testing machines on pl
22、ane-parallel, polished specimens of various materials in different heat treatment conditions. Tensile strength was tested on machines whose force measuring and extension measuring systems had been calibrated immediately before testing. The tensile test method used is equivalent to that specified in
23、ISO 6892, and the calibration procedures conform with those specified in ISO 7500-1 and ISO 9513. Users of this International Standard should take note of Clause 3, especially the concluding warning.
