ASTM D2240 is an international standard test method used to measure the hardness of rubber and elastomers using a durometer. The durometer is an instrument that has a standardized indenter and a spring-loaded mechanism that applies a specific amount of force to the material being tested. The indenter is pressed into the surface of the material, and the depth of the indentation is used to determine the hardness of the material. The results of this test can be used to compare the hardness of different materials or to monitor changes in the hardness of a material over time. The test method specifies several different types of durometers, which vary in the shape and size of the indenter and the force applied. The most common type of durometer is the Shore durometer, which uses a conical indenter and is widely used for measuring the hardness of rubber and elastomers.

NextGen’s Classic Analogue Shore Durometer complies with ASTM D2240 standard.
