Scope

This document specifies a method for determining the indentation hardness and indentation modulus of elastic-plastic materials using a linear elastic dynamic instrumented indentation test, in which an oscillating force or displacement is superimposed during the process of maintaining the target value of indentation force or displacement constant or continuously loading to the specified target value of force or displacement.
