This specification applies to the determination of Vickers hardness of metallic materials using an applied force from 1 kgf. to kgf. Part B is applicable to the verification of the Vickers hardness testing machines. The Vickers Hardness Test consists of a small pyramid shaped. per ASTM E (re-approved ) and ASTM E Summary of Test Method: Vickers is an indentation hardness test using calibrated machines to force. ASTM E VICKERS HARDNESS. This test method covers the determination of the Vickers hardness of metallic materials, using applied forces of 1 kgf to

While Committee E28 is primarily concerned with metallic materials, the test procedures described are applicable to other materials. Other materials may astm e92 special considerations, for example see C and C for ceramic testing.

Today, the hardness numbers are internationally defined in terms of SI units, that is, the test force in Newtons Astm e92. This standard has been approved for use by agencies of the U.

The significant differences between the two tests are the geometries of the respective indenters, the qstm of calculation of the hardness numbers, and that Astm e92 hardness may be used at higher force levels than Knoop hardness.

However, because of the historical precedent and continued common usage, force values in gf and kgf units are provided for information and much of the discussion in this standard as well as the method of reporting the test results refers to astm e92 units.

Other materials may require 9e2 considerations, for example see Astm e92 and Astm e92 for ceramic testing. NOTE 1—The Vickers and Knoop hardness s92 were originally defined in terms of the test force in kilogram-force kgf and the surface area or projected area in millimetres squared mm 2.

However, in practice, the most commonly used astm e92 units are kilogram-force kgf and gram-force asmt. However, because of astm e92 historical precedent and continued common usage, force values in gf and kgf units are provided for information and astm e92 of the discussion in this standard as well as the method of reporting the test results refers to these units.

However, in practice, the most commonly used force units are kilogram-force kgf and gram-force gf. This standard provides the requirements for Vickers and Knoop hardness machines and the procedures for performing Vickers and Knoop hardness tests.

However, in practice, the most commonly used force units are kilogram-force kgf and gram-force gf. For isotropic materials, the two diagonals of a Vickers indentation are equal in length. However, because of the historical precedent and continued common usage, force values in gf and kgf units are provided for information and much of the discussion in this standard as well as the method of reporting the test results refers to these units.
