Vickers Hardness Testing Machine Specification

Duramin 150 an entry level rockwell automatic hardness tester for high accuracy and a short cycle time.

Vickers hardness testing machine specification.

Same hardness number is obtained on the same specimen regardless of the load applied. As specialists we can also offer bespoke fixtures and automatic systems to ensure your specific needs are met. The vickers hardness test method consists of indenting the test material with a square base pyramid shaped diamond. An efficient vickers knoop and brinell automatic hardness tester offering micro macro and universal testing in one machine.

Vickers testing machines shall be verified periodically using test blocks. The unit of hardness given by the test is known as the vickers pyramid number hv or diamond pyramid hardness dph. Vickers hardness tester testing range is very wide from soft metal such as lead upto the hardest like hardeness steel. When hardness testing of welds a series of measurements are made in a given pattern at a specific distance from the sample edge or top of the weld.

Verification checking or testing to assure conformance with the specification. Designed for both vickers and knoop testing conform international standards iso 6507 and astm e384 segment leading load range 0 01 2 kgf load range over nine 9 individual load steps increased ease of use with automation. The vickers test can be used for all metals and has one of the widest scales among hardness tests. 1 4 this test method covers vickers hardness tests made utilizing test forces ranging from 9 807 10 3 n to 1176 80 n 1 gf to 120 kgf and knoop hardness tests made utilizing test forces from 9 807 10 3 n to 19 613 n 1 gf to 2 kgf.

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. The vickers method is based on an optical measurement system where the output is measured by the diagonal of the impression. The progression of the hardness values can then be plotted in a graph. Vickers hardness testing machines blue star e e offers a wide range of robust vickers hardness testers.

The hardness number can be converted into units of pascals but should not be confused with pressure which uses the same units. Vickers tests at 1000 gf can be utilized for determination of the bulk hardness but as for any hardness test it is recommended that a number of indents are made and the average and standard deviation are calculated as needed or as required. The indication is tiny and allows testing of a precision finished part. Loading and unloading cycle is motorised.
