I,p — 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. Enter your personal account email address to request a password reset: Are you sure you want to empty the cart?

Some manufactures are promoting that they have watch glass at Vickers compared to other watches rating at Vickers hardness test A Vickers hardness tester. An indentation left in case-hardened steel after a Vickers hardness test. You need to log in before adding standards to the monitoring service. Read more about subscriptions.

No further reproductions authorized. 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. 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 hardness number can be converted into units of pascalsbut should not be confused with pressure, which also has units of pascals. Originally approved in 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.

Vickers hardness test

The last approved version of this historical standard is referenced on www. This leads to the following equation: The electronic file may not be reproduced in any way. 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 w384 high resistance to self-deformation.

To calculate Vickers hardness number using SI units one needs to convert the force applied from newtons to kilogram-force by dividing by 9.

Vickers values are generally independent of the test force: This is not a good indentation. 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.
