Microindentation hardness tests also allow specific phases or constituents and regions or gradients too small for macroindentation hardness testing to be evaluated. Current edition approved April 1, When Newton units of force are used, the force must be divided by the conversion factor 9.

ASTM E92 – 82() Standard Test Method for Vickers Hardness of Metallic Materials

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. Other materials may require special considerations, for example see C and C for ceramic testing.

When Newton units of force are used, the force must be divided by the conversion factor 9. Subscription pricing is determined by: Already Subscribed to this document. NOTE 1—The Vickers and Knoop hardness numbers 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.

This standard provides the requirements for Vickers and Knoop hardness machines and the procedures for performing Vickers and Knoop hardness tests. Recommendations for microindentation testing can be found in Test Method E Today, the hardness numbers are internationally defined in terms of SI units, that is, the test force in Newtons N.

Today, the hardness numbers are internationally defined in terms of SI units, that is, the test force in Newtons N. Add to Alert PDF. This standard provides the requirements for Vickers and Knoop hardness machines and the procedures for performing Vickers and Knoop hardness tests.

ASTM E92 – 17

It is the e29 of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Anumber in parentheses indicates the year of last reapproval.

Current edition approved Feb. Last previous edition approved in as E92—82 which was withdrawn July and reinstated in February This standard is also available to be included in Standards Subscriptions. Standards Subsctiption may be the perfect solution. Hardness, although empirical in nature, can be correlated to tensile strength for many metals, and is an indicator of wear resistance and ductility. 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.

Aztm materials may require special considerations, for example see C and C for ceramic testing. This standard has been approved for use by agencies of the U.

The significant differences between the two tests are the geometries of the ast indenters, the method of calculation of the hardness numbers, and that Vickers hardness may be used at higher force levels than Knoop hardness. Originally approved in While Committee E28 is primarily concerned with metallic materials, the test procedures described are applicable to other materials.

Link to Active This link will always route to the current Active version of the standard. However, in practice, the most commonly used force units are kilogram-force kgf and gram-force gf. 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. When Newton units of force are used, the force must be divided by the conversion factor 9. However, in practice, the most commonly used force units are kilogram-force kgf and gram-force gf.
