DIN Standards Committee Materials Testing

Overview

This part of ISO 14577 specifies the method of verification and calibration of testing machines for carrying out the instrumented indentation test in accordance with ISO 14577-1:2015. It describes a direct verification method for checking the main functions of the testing machine and an indirect verification method suitable for the determination of the repeatability of the testing machine. There is a requirement that the indirect method be used in addition to the direct method and for the periodic routine checking of the testing machine in service. It is a requirement that the indirect method of verification of the testing machine be carried out independently for each test method. This part of ISO 14577 is also applicable for transportable testing machines. This document (EN ISO 14577-2:2015) has been prepared by Technical Committee ISO/TC 164 "Mechanical testing of metals", Subcommittee SC 3 "Hardness testing" (secretariat: DIN, Germany) and has been adopted by Technical Committee ECISS/TC 101 "Test methods for steel (other than chemical analysis)" (secretariat: AFNOR, France) in accordance with the Vienna Agreement. The responsible German body is Working Committee NA 062-01-41 AA "Härteprüfung für Metalle" ("Hardness testing for metals") at DIN Standards Committee Materials Testing (NMP).
