DIN EN ISO 16859-3:2016-02

This part of ISO 16859 specifies a method for the calibration of reference test blocks that are used for the indirect verification of Leeb hardness testers according to ISO 16859-2 and for the periodic checking according to ISO 16859-1. The procedures necessary to ensure metrological traceability of the calibration machine are also specified. This document (EN ISO 14556-3:2015) has been prepared by Technical Committee ISO/TC 164 "Mechanical testing of metals", Subcommittee SC 4 "Hardness testing" (secretariat: DIN, Germany) and adopted by ECISS/TC 101 "Test methods for steel (other than chemical analysis)" (secretariat: AFNOR, France) in accordance with the Vienna Agreement. The responsible German committee is Working Committee NA 062-01-41 AA "Härteprüfung für Metalle" ("Hardness testing for metals") at DIN Standards Committee Materials Testing (NMP).
