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. This standard has been approved for use by agencies of the Department of Defense. No further reproductions authorized. Smith and George E. 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 hardness number can be converted into 1e2 of pascalsbut should not be confused with pressure, which also has units of pascals. As a rule of thumb the sample thickness should be kept greater than 2. Currently some watch companies are improving the crystal watch glass by testing the strength using the Vickers hardness test.

Vickers Hardness Testing of Metallic Material that was under the jurisdiction of. ASTM grants you a license as follows: Meyer hardness test Rockwell scale Vickers toughness test of ceramics. 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. 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.

Please login to your authorized staff account to use this feature. 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.

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.
