What is Barcol Durometer?

The unit of Barcol hardness tester is bar (Ba). One Barcol hardness unit is equal to the force applied by the indenter when it presses into the material being tested by one millimeter.

The calculation formula of Barcol hardness tester is: Ba = 0.1mm × g / F, where Ba is the Barcol hardness value, 0.1mm is the diameter of the indenter, g is the acceleration of gravity, and F is the pressure.

The indenter of the Barcol hardness tester is conical with a taper of 1/16, a test time of 10-30 seconds, and a test pressure of 98N. The Barcol hardness tester can be used to test the hardness of various materials such as metals, plastics, and rubber. It is simple to operate and inexpensive, and is a commonly used hardness testing instrument.

During the test, the Barcol hardness tester needs to keep the indenter position perpendicular to the surface of the sample to avoid tilting or deviation. At the same time, it is necessary to select the appropriate indenter and load according to different materials to obtain accurate test results. After using the Barcol hardness tester, the test platform and indenter need to be cleaned and kept dry. Calibration and maintenance should be performed regularly to ensure the accuracy and stability of the equipment.

In short, the Barcol hardness tester is a simple, practical and reliable hardness testing instrument. Its unit is bar (Ba), which can be used to test the hardness of a variety of materials. When using the Barcol hardness tester, you need to pay attention to some details, such as keeping the indenter in a vertical position, selecting the appropriate indenter and load, regular calibration and maintenance, etc., to ensure accurate and reliable test results.
