International Rubber Hardness Degree Meter used to determine the Hardness of Rubber Components where highly accuracy and reliable determination of the Hardness is of extreme important. The principal behind determination ofhardness by dead load apparatus is based on the measurement of the difference between the depth of indentation of a standard ball in to the rubber under a small contact force and a large indenting force. This type of hardness determination is widely accepted by I.S, B.S and I.S.O specification.
