Standard Test Methods for Differential Indentation Depth Hardness of Metallic Materials

Importancia y uso:

4.1 The Differential Indentation Depth hardness test is an empirical indentation hardness test that can provide useful information about metallic materials. This information can correlate to tensile strength, wear resistance, ductility, and other physical characteristics of metallic materials, and can be useful in quality control and selection of materials.

4.2 Differential Indentation Depth hardness tests are considered satisfactory for acceptance testing of commercial shipments, and have been used in industry for this purpose.

4.3 Differential Indentation Depth hardness testing at a specific location on a part might not represent the physical characteristics of the whole part or end product. Machines that comply with this Standard are used when machines that comply with the regular hardness standards such as Test Methods E10, E18, E92, and E384 cannot be used. Test results obtained with these machines are comparable BUT NOT EQUIVALENT to those obtained with machines that comply with the above mentioned standards.

4.4 Differential Indentation Depth hardness testing machines covered by this standard do not comply with Test Methods E10, E18, E92, or E110.
