Standards monitoring is a free service designed for you who wish to be alerted of changes to or new editions of the standards required in your work. Alternatively indent depth can be calculated according to:. Originally approved in A diamond in the form of a square-based pyramid satisfied these conditions. Last previous edition approved in as E348 — 10e2.
NOTE 1—Previous versions of this standard limited test forces to 9. A web subscription provides an easy and secure access to standards, and you are guaranteed to always have the latest edition. ASTM grants you a license as follows: However, on the astmm flying Partnair Flight the pins were later found to have been replaced with sub-standard parts, leading to rapid wear and aastm loss of the aircraft. The right to access the electronic files of ASTM Standards is for purposes of viewing for individual use only.
Monitoring Standards monitoring is a free service designed for you who wish to be alerted of changes to or new editions of the standards required in your work. The moment new editions of the standards you monitor are released, changes are made, or appendixes are published, you will be alerted by email. Search book title Enter keywords for book title search. This leads to the following equation: Vickers hardness numbers are reported as xxxHVyye.

ASTM E – 10e2 Standard Test Method for Knoop and Vickers Hardness of Materials
Qstm currently cannot view this content. 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 edge.

In addition the electronic files may not be downloaded or distributed elsewhere over computer networks or otherwise.
Vickers values are generally independent of the test force: 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.
The Vickers e34 test was developed in by Robert L. Subscription – always available and updated A web subscription provides an easy and secure access to standards, and you are guaranteed to always have the latest edition. No items in cart. 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 procedures described are applicable to other materials.
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.

The angle was varied experimentally and it was found that the hardness value obtained on a qstm piece of material remained constant, irrespective of load. To calculate Vickers hardness number using SI units one needs to convert the force applied from newtons to kilogram-force by dividing by 9. Currently some watch companies are improving the crystal watch glass by testing the strength using the Vickers hardness aetm.
