Standard Test Method for Composite Foam Hardness-Durometer Hardness

Importancia y uso:

4.1 This test method is based on the penetration by a specific type of indentor when forced into the material under specified conditions. The indentation hardness is related inversely to the penetration and is dependent on the elastic modulus and viscoelastic behavior of the material. The geometry of the indentor and the applied force influence the measurements, such that no simple relationship exists between the measurements obtained with one type of durometer and those obtained with another type of durometer or other instruments used for measuring hardness. This test method is an empirical test intended primarily for control purposes. No simple relationship exists between indentation hardness determined by this test method and any fundamental property of the material tested. For specification purposes it is recommended that Test Method D785 be used for hard materials and Test Method D2240 be used for solid elatomers.
