type A shore durometer
type D shore durometer
Principle
A specified indenter is forced into the test material under specified conditions and the depth of penetration measured .
The indentation hardness is inversely related to the penetration and is dependent on the modulus of elasticity and the viscoelastic properties of the material .

* The dimensions of the test specimen shall be sufficient to permit measurements at least 9 mm away from any edge.
* The surface of the test specimen shall be flat.
