Vickers hardness test
A diamond in the form of a square-based pyramid satisfied these conditions. The fin attachment pins and sleeves in the Convair airliner were specified by the aircraft manufacturer to be hardened to a Vickers Hardness specification of HV5, the ‘5’ meaning five kiloponds. An indentation left in case-hardened steel after a Vickers hardness test.

NOTE 2—While Committee E04 is primarily concerned with metals, the test procedures described are applicable to other materials. The last approved version of this historical standard is referenced.
Webprint Printed and bound. The basic principle, as with all common measures of hardness, is to observe the questioned ee384 ability to resist plastic deformation from a standard source.

E84 previous edition approved 10ee2 as E — 10e2. Remember me for one month. When doing the hardness tests the minimum distance between indentations and the distance from the indentation to the edge of the specimen must be taken into account to avoid interaction between the work-hardened regions and effects of the wstm.
With this revision the test method was expanded to include the requirements previously defined in E The angle was varied experimentally and it was found that the hardness value obtained on a homogeneous piece of material remained constant, irrespective of load.
This standard is issued under the fixed designation E; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. To calculate Vickers hardness number using SI units one needs to convert the force applied from newtons to kilogram-force by dividing by 9.
