ASTM E 384 : 2009

These test methods cover procedures and definitions for the mechanical testing of wrought and cast steels, stainless steels, and related alloys.

1.1 This test method covers determination of the microindentation hardness of materials, the verification of microindentation hardness testing machines, and the calibration of standardized test blocks.

1.2 This test method covers microindentation tests made with Knoop and Vickers indenters under test forces in the range from 9.8 × 10^-3 to 9.8 N ( 1 to 1000 gf ).

1.3 This test method includes an analysis of the possible sources of errors that can occur during microindentation testing and how these factors affect the accuracy, repeatability, and reproducibility of test results.

Note 1—While Committee E04 is primarily concerned with metals, the test procedures described are applicable to other materials.

1.4 This standard does not purport to address all of the safety concerns, 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.
