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).
ASTM Committees E28 and E04 collaborated to merge the procedures and requirements of Test Method E92 with Test Method E384 in order to have all Vickers hardness testing requirements in one single place under the jurisdiction of one Committee E04.
Formerly under the jurisdiction of Committee E28 on Mechanical Testing, this test method was withdrawn in July 2010 and replaced by Test Method E384 for Knoop and Vickers Hardness of Materials
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.
