ISO 14577-1:2002 , Metallic materials -- Instrumented indentation test for hardness and materials parameters -- Part 1: Test method

This part of ISO 14577 specifies the method of instrumented indentation test for determination of hardness and other materials parameters for the three ranges given in Table 1.The macro and micro range are distinguished by the test forces in relation to the indentation depth.Attention is drawn to the fact that the micro range has an upper limit given by the test force (2 N) and a lower limit given by the indentation depth of 0,2 μm.The determination of hardness and other materials parameters is given in annex A.At high contact pressures, damage to the indenter is possible. For this reason in the macro range, hardmetal indenters are often used. For test pieces with very high hardness and modulus of elasticity the influence of indenter deformation on the test result should be taken into account.
