ASTM E92-82(2003)e1 - 10.1.2003
 
1. Scope

1.1 This test method covers the determination of the Vickers hardness of metallic materials, using applied forces of 1 kgf to 120 kgf, the verification of Vickers hardness testing machines (Part B), and the calibration of standardized hardness test blocks (Part C). Two general classes of standard tests are recognized:

1.1.1 Verification, Laboratory, or Referee Tests, where a high degree of accuracy is required.

1.1.2 Routine Tests where a somewhat lower degree of accuracy is permissible.

1.2 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.
