External dimensions/Mass
* For elastic materials such as rubber, measurement cannot be performed. The principle behind the Leeb hardness test is that the hardness is obtained by the rebound behavior of an impact hammer after a light blow on the specimen. Therefore be aware that the test results are susceptible to the effect of the size (especially thickness) and surface roughness of a workpiece.
