The Shore hardness measurement is a test method used to evaluate the surface hardness or elasticity of a material. This measurement is used to determine the physical properties of a material, to carry out quality controls or to check the compliance of a material. The Shore hardness measurement is conducted by means of Shore hardness gauges or penetrometers of various grades and types. There are two widely-used systems for Shore hardness measurements: Shore A and Shore D, each addressing the requirements of different operations. Shore A hardness measurements are used to evaluate the hardness of elastomers, rubbers and similar flexible materials. Shore D hardness measurements are used to evaluate the hardness of harder plastics, thermoplastics and similar materials.
