Originally approved in This standard provides the requirements for Vickers and Knoop hardness machines s92 the procedures for performing Vickers and Knoop hardness tests.

This standard provides the requirements for Vickers and Knoop hardness machines and the procedures for performing Vickers and Knoop hardness tests. Other materials may require special considerations, for example see C and C for ceramic testing. Standards Subsctiption may be the perfect solution. This rise in hardness number with lower test forces is often more significant when testing higher hardness materials, and is increasingly more significant when using test forces below 50 gf see Test Method E NOTE 2—While Committee E28 is primarily concerned with metallic materials, the test procedures described are applicable to other materials.

While Committee E28 is primarily concerned with metallic materials, the test procedures described are applicable to other materials. When Newton units of force are used, the force must be divided by the conversion factor 9.

ASTM E92 – 17 – Standard Test Methods for Vickers Hardness and Knoop Hardness of Metallic Materials

However, because of the historical precedent and continued common usage, astk 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. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server.

The significant differences between the two tests are the geometries of the respective indenters, the method of calculation of the hardness numbers, and that. 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.

Ast, pricing is determined by: This standard has been approved for use by agencies of the U. 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.

Today, the hardness numbers are internationally defined in terms of SI units, that is, the test force in Newtons N. This standard is not included in any packages. Vickers and Knoop Hardness Standardizing Machines. 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.

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. Already Subscribed xstm this document.

Hardness, although empirical in nature, can be correlated to tensile ast, for many metals, and is an indicator of wear resistance and ductility. Anumber in parentheses indicates the year of last reapproval. 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 Vickers hardness may be used at higher force levels than Knoop hardness.

Microindentation hardness tests also allow specific phases or constituents and regions or gradients too small asrm macroindentation hardness testing to be evaluated. Other materials may require special considerations, for example see C and C for ceramic testing.
