The standard KS MISO 868-2001 Plastics and Hard Rubber, Measurement of Indentation Hardness with a Hardness Tester (Shore Hardness) specifies the method of measuring the indentation hardness of plastic and hard rubber materials using a Shore hardness tester. The Shore hardness test determines the hardness value of the material by pressing a steel ball or diamond indenter of a certain standard into the surface of the material and measuring the indentation depth within a specified time. To ensure the accuracy of measurement, the standard specifies the operation steps of the hardness tester, the preparation of the sample, the testing environment and the method of recording the data. It is suitable for hardness testing of various plastic and hard rubber materials and provides an important basis for product quality control, material research and development and performance evaluation.
