Shore hardness tester

The hardness testers are instruments specifically designed to detect the hardness of materials. To make a measurement of the hardness of a material, the durometer should do about it penetration, leaving an imprint on the point tested (called a witness).

Non destructive testing instrument employed to measure the hardness in rubber, plastics, sponges and similar mediums. Shore A hardness testers are the most used to measure thermoplastic elastomers. A 0 zero reading means the penetrator reached its max depth in the material, while a 100 reading shows lack of indentation in the sample. Over 90 Shore A readings it’s suggested to employ Shore D hardness testers, given its sharper penetrator. Below 5 Shore A readings it’s suggested to employ a Shore C hardness tester. Shore hardness testers are suitable in quality control in rubber and plastics industries and in maintenance checks on ring nuts and gaskets. Conform to standards DIN53505, ASTM D2240, ISO7619, JIS K7215.
