To determine these differences requires a very small physical indentation. However, because of the historical precedent and continued common usage, force values in gf and kgf units are provided for information and much of the discussion in this standard as well as the method of reporting the test results e3844 to these units.

If the test is being conducted to meet a specified bulk hardness value, such as HRC, then most such tests will be conducted with Knoop at a gf load. Recommendations for low force microindentation testing can be found in Appendix X5. Remember me for one month.
Your Alert Profile lists the documents that will be monitored. Note 2—While Committee E04 is primarily concerned with metals, the test procedures described are applicable asrm other materials.
Hardness, although empirical in nature, can be correlated to tensile strength for many metals and alloys, and is also an indicator of machinability, wear resistance, toughness and ductility. As the voice of 1e11 U.

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. The majority of Knoop tests of case hardness variations are conducted at forces from to gf. No other units of measurement are included in this standard.

Microindentation tests permit hardness testing of specific phases or constituents and regions or gradients too small for evaluation by macroindentation tests. NOTE 2—While Committee E04 is primarily concerned with metals, the test procedures described are applicable to other materials.
