ASTM grants you a license as follows: Enter your account email address to request a password reset: No further reproductions authorized. 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.
Remember me for one month. Vickers hardness test A Vickers hardness tester. The difference in length of both diagonals and the illumination gradient, are both classic indications of an out-of-level sample. Are you sure you want to empty the cart?

With this revision the test method was expanded to f384 the requirements previously defined in E The right to access the electronic files of ASTM Standards is for purposes of viewing for individual use only.
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. Currently some watch companies are improving the crystal watch glass by testing aastm strength using the Vickers hardness test.
Start Webshop Product catalog Aatm presentation. 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.
This standard has been approved for use by agencies of the Department of Defense.
The electronic file may not be atm in any way. For thin samples indentation depth can be an issue due to substrate effects. Read more about subscriptions. Current edition approved Aug. A number in parentheses indicates the year of last reapproval. NOTE 1—Previous versions of this standard limited test forces to 9.
Meyer hardness test Rockwell scale Vickers toughness test of ceramics. Last previous edition approved in as E — 10e2. NOTE 2—While Committee E04 is primarily concerned with metals, the test procedures described are applicable to other materials.
In addition the electronic files may not be downloaded or distributed elsewhere over computer networks or otherwise. You need to log in before adding standards to the monitoring service. The Vickers test can be used for all metals and has one of the widest scales among hardness tests. Register for a trial account.
Vickers hardness test
The benefits of a subscription: Vickers hardness numbers are reported as xxxHVyye. Webprint Printed and bound. The last approved 10e22 of this historical standard is referenced on www.
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.
Awtm hardness number can be converted into units of pascalsbut should not be confused with pressure, which also has units of pascals. The pyramidal diamond indenter of a Vickers hardness tester. As a rule of thumb the sample thickness should be kept greater than 2.

On examination, accident investigators found that the sub-standard pins had a hardness value of only some HV5.
To calculate Vickers hardness number using SI units one needs to convert the force applied from newtons to kilogram-force by dividing by 9.
