About

Scope

Standardization in the field of indentation testing; specifying different indentation test methods, primarily for metals testing, at length scales ranging from nano to macro. Methods include the measurement of Brinell, Knoop, Leeb, Rockwell and Vickers hardness and also Instrumented Indentation Testing (at ambient and elevated temperatures) for hardness and materials parameters including indentation elastic modulus (both quasi-static and dynamic), indentation creep, elastic and plastic work of indentation, and relative average surface stress. Also included are methods for the verification and calibration of indentation testing and calibration machines, the calibration of reference blocks, the calculation of measurement uncertainties, and the conversion of hardness values.
