1. Scope

1.1 This test method covers the determination of indentation

hardness of metallic materials using comparison hardness

testers.

1.2 This test method applies only to those portable compari-

son hardness testers that use test bars that have been standard-

ized according to Test Method E10 as a basis for comparison.

1.3 Calibration of test bars, used for comparison to deter-

mine hardness numbers, is also covered by this test method.

1.4 The impression force used during comparison hardness

testing is normally an impact load applied by striking a

hammer on the appropriate areas as outlined in the manufac-

turer’s instructions.

1.5 The values stated in SI units are to be regarded as

standard. No other units of measurement are included in this

standard.

1.6 This standard does not purport to address all of the

safety problems, if any, associated with its use. It is the

responsibility of the user of this standard to establish appro-

priate safety, health, and environmental practices and deter-

mine the applicability of regulatory limitations prior to use.

1.7 This international standard was developed in accor-

dance with internationally recognized principles on standard-

ization established in the Decision on Principles for the

Development of International Standards, Guides and Recom-

mendations issued by the World Trade Organization Technical

Barriers to Trade (TBT) Committee.
