ASTM E103-84(1996)

This test method is used when it is desired to make hardness tests very rapidly, as in the inspection of the output of a heat-treating furnace.

This test method is not to be regarded as a standard Brinell hardness test method.

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.

A. GENERAL DESCRIPTION AND TEST PROCEDURE

1.1 This test method covers the procedure for rapid indentation hardness testing of metallic materials as an alternative to Test Method E 10 on standard Brinell hardness. It includes methods for the verification of rapid indentation hardness testing machines, Part B, and the calibration of reference hardness test blocks, Part C.

1.2 The values stated in SI units are to be regarded as standard.

1.3 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.
