Some basic information about Shore hardness measurement

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.
