1. Scope

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.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the

Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3. Terminology

3.1 Definitions:

3.1.1 calibration—determination of the values of the significant parameters by comparison with values indicated by a reference instrument or by a set of reference standards.

3.1.2 rapid indentation hardness test—an indentation hardness test using calibrated machines to force a tungsten carbide ball, under specified conditions, into the surface of the material under test and to measure the depth of the indentation. The depth measured can be from the surface of the test specimen or from a reference position established by the application of a preliminary test force. The depth measurement is usually correlated to another scale or Brinell hardness number.

3.1.3 verification—checking or testing to assure conformance with the specification.
