ISO 16859-3:2015 PDF

Scope: 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.
