If the document is revised or amended, you will be notified by email. NOTE 2—While Committee E28 is primarily concerned with metallic materials, the test procedures described are applicable to other materials.

Today, the hardness numbers are internationally defined in terms of SI units, that is, the test force in Newtons N. You may delete a document from sstm Alert Profile at any time.

This standard provides the requirements for Vickers and Knoop hardness machines and the procedures for performing Vickers and Knoop hardness tests. 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. Standards Subsctiption may be the perfect solution. Recommendations for microindentation testing can be found in Test Method E Other materials may require special considerations, for example see C and C for ceramic testing.

This standard provides the requirements for Vickers and Knoop hardness machines and the procedures for performing Vickers and Knoop hardness tests. 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.

ASTM E92 – 17

This standard provides the requirements for Vickers and Knoop hardness machines and the procedures for performing Vickers and Knoop hardness tests. The significant differences between the two tests are the geometries of the respective indenters, the method of calculation of the hardness numbers, and that. The significant differences between the two tests are the geometries of the respective indenters, the method of calculation of the hardness numbers, and that Vickers hardness may be used at higher force levels than Knoop hardness.

While Committee E28 is primarily concerned with metallic materials, the test procedures described are applicable astn other 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. NOTE 2—While Committee E28 is primarily concerned with metallic materials, the test procedures described are applicable to other materials. We have no amendments or corrections for this standard. Microindentation hardness tests also allow specific phases or constituents and regions or gradients too small for macroindentation hardness testing to be evaluated.

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. 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 e9 well as the method of reporting the test results refers to these units.

This standard is issued ast, the fixed designation E92; the number immediately following the designation indicates the year of original. When Newton units of force are used, the force must be divided by the conversion factor 9. Your Alert Profile lists the documents that will be monitored. As the voice of the U. F92 standard asrm been approved for use by agencies of the U. However, in practice, the most commonly used force units are kilogram-force kgf and gram-force gf.

Please first verify your email before subscribing to alerts. Today, the hardness numbers are internationally defined in terms of SI units, that is, the test force in Newtons N. Other materials may require special considerations, for example s92 C and C for ceramic testing. This standard is not included in any packages. This standard has been approved for use by agencies of the U. Hence, the Knoop hardness test is very useful for evaluating hardness gradients since Knoop indentations can be made closer together than Vickers indentations by orienting the Knoop indentations with the short diagonals in the direction of the hardness gradient.

When Newton units of force are used, the force must be divided by the conversion factor 9.

This standard is issued under the fixed designation E92; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. Last previous edition approved in as E92— Today, the hardness numbers are internationally defined in terms of SI units, that is, the test force in Newtons N. When Newton units of force are used, the force must be divided by the conversion factor 9.

Vickers and Knoop Hardness Standardizing Machines. NOTE 1—The Vickers and Knoop hardness numbers were originally defined in terms of the test atm in kilogram-force kgf and the surface area or projected area in millimetres squared mm 2.
