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. However, on the aircraft flying Partnair Flight the pins were later found to have been replaced with sub-standard parts, leading to rapid wear and finally loss of the aircraft.

Ee2 Standard Test Method for Knoop and Vickers Hardness of Materials, –
Vickers hardness adtm are reported as xxxHVyye. The Vickers test can be used for all metals and has one of the widest scales among hardness tests.
The hardness number is determined by the load over the surface area of the indentation and not the area normal to the force, and is therefore not pressure.

It was decided that the indenter shape should be capable of producing geometrically similar impressions, irrespective of size; the impression should have well-defined points of measurement; and the indenter should have high resistance to self-deformation. This is not a good indentation.
Vickers hardness test
With this revision the test method was expanded to include the requirements e38 defined in E In addition the electronic files may not be downloaded or distributed elsewhere over computer networks or otherwise. 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.

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. Print 1 2 3 4 5 page sstarting from page current page. NOTE 1—Previous versions of this standard limited test forces to 9.
The basic principle, as with all common measures of hardness, is to observe the questioned material’s ability to resist plastic deformation from a standard source. NOTE 2—While Committee E04 is primarily concerned with metals, the test s384 described are applicable to other materials.
To calculate Vickers hardness number using SI units one needs to convert the force applied from newtons to kilogram-force by dividing by 9. The last approved version of this historical standard is referenced. An indentation left in case-hardened s384 after a Vickers hardness test. For thin samples indentation depth can be an issue due to substrate effects.
