Metallic materials — Instrumented indentation test for hardness and materials parameters Part 3: Calibration of reference blocks Published (Edition 3, 2026)

Abstract

This document specifies a method for the calibration of reference blocks to use for the indirect verification of testing machines for the instrumented indentation test as specified in ISO 14577-2.

Reference materials, where it is necessary to prepare a surface before the test in a manner that removes surface layers are excluded from this standard.
