Standard Test Method for Rubber Property—Durometer Hardness
Standard Test Method for Rubber Property—Durometer Hardness
Scope:
This test method describes twelve types of rubber hardness measurement devices known as durometers:
Types A,B, C, D, DO, E, M, O, OO, OOO, OOO-S, and R.
Significance:
This test method is based on the penetration of a specific type of indentor when forced into the material under specified conditions.
The indentation hardness is inversely related to the penetration and is dependent on the elastic modulus and viscoelastic behavior of the material.
ASTM 2240- 03
