Durometer Hardness is used to determine the relative hardness of soft materials, usually plastic or rubber. The test measures the penetration of a specified indentor into the material under specified conditions of force and time. The hardness value is often used to identify or specify a particular hardness of elastomers or as a quality control .

How Do You Measure Shore Hardness. The Shore Scale was created by Albert Shore back in the 1920s. He was a metallurgist and is credited as the founder of the durometer, which is the instrument used to measure Shore hardness.A durometer gauge is used to measure Shore hardness and is a relatively simple device. It contains a spring-loaded steel .ASTM D2240 durometers allow for a measurement of the initial hardness, or the indentation hardness after a given period of time. The basic test requires applying the force in a consistent manner, without shock, and measuring the hardness (depth of the indentation). If a timed hardness is desired, force is applied for the required time and then .Figure 3 is a simplified graphic representation of a Shore durometer hardness test.
