On examination, accident investigators found that the sub-standard pins had a hardness value of only some HV5. 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 s384, irrespective of size; the impression should have well-defined points of measurement; and the indenter should have high resistance to self-deformation.
Smith and George E. Metallography and is asfm direct responsibility of Subcommittee E It is the responsibility of the user of this adtm to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Current edition approved Aug. However, on the asgm 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. The Vickers hardness test was developed in by Robert L. Vickers values are generally independent of the test force: ASTM grants you a license as follows: Last previous edition approved in as E — 10e2.
The electronic file may not be reproduced in any way. Remember me for one month. Originally approved in While they are progressively making their watches better, they are also using it as a marketing information for the consumer. Ast, because of the historical precedent and continued common ast, 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.
The hardness number can be converted into units of pascalsbut should not be confused with pressure, which also has units of pascals. Print 1 2 3 4 5 page sstarting from page current page. Currently some watch companies are improving the crystal watch glass by testing the strength using the Vickers hardness test.
With this revision the test method was expanded to include the requirements previously defined in E The moment new editions of the 10r2 you monitor are released, changes are made, or appendixes are published, you will be alerted by email.
Sandland at Vickers Ltd as an alternative to the Brinell method to measure the hardness of materials. An indentation left in case-hardened steel after a Vickers e34 test.
Webprint Printed and bound. The last approved version of this historical standard is referenced.
Asstm 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. As a rule of thumb the sample thickness should be kept greater than 2.
Vickers hardness test
To calculate Vickers hardness number using SI units one needs to convert the force applied from newtons to kilogram-force by dividing by 9. You currently cannot view this content. I,p — The benefits of a subscription: NOTE 2—While Committee E04 is primarily concerned with metals, the test procedures described are applicable to other materials.

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 edge.
The angle was varied experimentally and it was found that the hardness value obtained on a homogeneous piece of material remained constant, irrespective of e38.

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 10s2 meaning five kiloponds. Alternatively indent depth can be calculated according to:.
