Hardness tester

from Wikipedia, the free encyclopedia

Hardness testers are devices with which comparative tests are carried out to determine the hardness .

The Shore , Brinell , Rockwell, and Vickers methods are the best known and most widely used.

A hardness tester generally has an indenter . With this, the sample is usually loaded with a defined force and a specified time. This creates an impression, which is then measured optically or manually with callipers . Alternatively, the depth of penetration is measured and evaluated.

To do a quick check, e.g. B. when checking incoming goods , handheld devices are used. The Webster pliers or the handy Shore device for rubber samples should be mentioned here.

In the meantime, many devices on the market are equipped with microprocessors and a PC to manage the data and to keep corresponding statistics .
