ASTM E384 Standard Test Method for Microindentation Hardness of Materials

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ASTM E384 testing. The ASTM E384 standard describes a hardness testing method that provides very useful data for the evaluation of materials used in production, quality control of manufacturing processes, and research and development.

The hardness level of the materials is empirically by nature, but is associated with tensile strength for many metals and alloys. Hardness level is also an indicator of the workability, abrasion resistance, toughness and ductility of the material.

Micro measurement tests are used to measure and evaluate changes in hardness that occur in a small area. These tests are important, for example, in blasting, cold drawing, flame hardening, induction hardening and similar surface hardening processes.

Microdentation hardness tests reveal hardness variations commonly found in many metal materials. Therefore, a single test value often does not represent bulk hardness.

Vickers tests are used to determine the mass hardness. However, as with any hardness test, a series of indentations must be made on the material and the mean and standard deviation calculated accordingly.

The ASTM E384 test method also analyzes the sources of errors that occur during the micro-measurement test and how these factors affect the accuracy, bias and repeatability of the test results.

Hardness is generally defined as the resistance of a material to permanent deformation such as indentation, wear, wear and scratch. The importance of the hardness test is closely related to the relationship between the hardness value and other properties of the material. For example, both the hardness test and the tensile test measure the resistance of a metal to plastic flow, and the results of these tests can be parallel to each other.

Values ​​stated in SI units should be accepted as standard. No other units of measurement are included in this standard.

This standard does not purport to address all, if any, safety concerns associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory restrictions prior to use.
