The work of preparing International Standards is normally carried out through ISO technicalcommittees.Eachmemberbodyinterestedinasubjectforwhichatechnicalcommitteehasbeer International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/lEc 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 Standard requires approval by at least 75 % of the member bodies casting a vote. rights.

ISO 7500-2 was prepared by Technical Committee ISO/TC 164, Mechanical testing of metals, Subcommittee SC 1, Uniaxial testing. This second edition cancels and replaces the first edition (isO 7500-2:1996), which has been technically revised. Iso 7500 consists of the following parts, under the general title Metallic materials - Verification of static uniaxialtestingmachines: Part 1: Tension/compression testing machines - Verification and calibration of the force-measuring system Part 2: Tension creep testi
