- Scope
The comparative hardness test is an empirical dynamic indentation hardness test. Comparative hardness tests provide useful information about metallic materials. This information may correlate to tensile strength, wear resistance, ductility, heat treatment condition, or other physical characteristics of metallic materials, and may be useful in quality control and selection of materials.
Comparative hardness testing at a specific location on a part may not represent the physical characteristics of the whole part or end product.
1.1 This practice covers the determination of indentation hardness of metallic materials using comparison hardness testers.
1.2 This practice applies only to those comparison hardness testers, normally portable, that use comparative test bars that have been standardized according to Test Method E 10
as a basis for comparison. 1.3 Calibration of comparative test bars (rods), used for comparison to determine hardness numbers, is also covered by this practice.
1.4 The impression force used during comparison hardness testing is normally an impact load applied by striking a hammer on the appropriate areas as outlined in the manufacturer''s instructions.
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.6 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
