Scope
1.1 This test method covers the determination of the Brinell
hardness of metallic materials by the Brinell indentation
hardness principle. This standard provides the requirements for
a Brinell testing machine and the procedures for performing
Brinell hardness tests.
1.2 This standard includes additional requirements in four
annexes:
Verification of Brinell Hardness Testing Machines Annex A1
Brinell Hardness Standardizing Machines Annex A2
Standardization of Brinell Hardness Indenters Annex A3
Standardization of Brinell Hardness Test Blocks Annex A4
1.3 This standard includes nonmandatory information in an
appendix which relates to the Brinell hardness test:
Table of Brinell Hardness Numbers Appendix X1
Examples of Procedures for Determining
Brinell Hardness Uncertainty
Appendix X2
1.4 At the time the Brinell hardness test was developed, the
force levels were specified in units of kilograms-force (kgf).
Although this standard specifies the unit of force in the
International System of Units (SI) as the Newton (N), because
of the historical precedent and continued common usage of kgf
units, force values in kgf units are provided for information and
much of the discussion in this standard refers to forces in kgf
units.
1.5 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.
