The NF T51-024-2-1999 standard specifies the determination method of rockwell hardness of plastic products. The standard details the steps for the measurement of plastic Hardness on different scales (M, L and R) using the Rockwell hardness tester. The Hardness value is related to the indentation of the material. The higher the Hardness value, the harder the material. Applicable to a variety of plastic materials, including materials with creeping and restorative properties, the result measurement is affected by the time factor. Provides a standardized how-to guide for hardness testing in the plastics industry.
