International Rubber Hardness Degree Meter is used to determine the Hardness of Rubber components where highly accuracy and reliable determination of the Hardness is of extreme important. The principle behind the determination of hardness by dead load apparatus is based on the measurement of the difference between the depth of indentation of a standard ball into 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.
