Book of Standards Volume: 03.01
Historical (view previous versions of standard)
Significance and Use
This practice is used when it is desired to make Brinell type hardness tests very rapidly on a high volume of samples, as in the inspection of the output of a heat-treating furnace.
This practice requires the measurement of indentation depth and eliminates the need to measure the diameter of the indent optically as required in a Brinell hardness test.
This practice is not a standard Brinell hardness test method and does not meet the requirements of Test Method E10.
4.4 Since the test forces and method of display of the depth measurement differ between manufacturers of rapid indentation hardness testing equipment, the test results from equipment from different manufacturers are not comparable.
1.1 This practice covers a procedure for rapid indentation hardness testing of metallic materials.
1.2 This practice includes additional requirements in Annex A1 for the direct, indirect, and daily verification of rapid indentation hardness testing machines.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
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.
