The hardness is obtained by the difference in penetration depth of a specified dimension ball under two conditions of contact with the rubber. a) with a small initial force b) with a much large final force The differential penetration is taken at a specified time and converted to a hardness scale value. The IRHD Tester made a vertical plunger. The lower side of the plunger has an indenter. The lower shape of the indenter is ball type of specified dimension. The upper sides of the plunger have a good eclectic conductive tip. The weight of the plunger and fitting attached to it is the minor force. A big brass weight is the major force of the specified weight. A dial gauge is attached to the instrument for the measurement of the penetration depth of the indenter to the rubber. An electricity operated buzzer, for gently vibrating the apparatus to overcome the slight friction is mounted under the cover of the instrument. The tester is finished in NC based painting and bright chrome plating to give it a corrosion resistance finish. RELATED STANDARD ASTM D 1415 – 81 –Rubber property – International Hardness

Presto IRHD Rubber Hardness Tester determines the hardness of rubber and rubber components. Hardness is one of the most important properties which determine the suitability of any rubber component for its intended use. Incorrect hardness of may defeat the basic purpose for which the component is designed. Thus, accurate and reliable determination of the hardness is of extreme importance in rubber industry. The Presto IRHD Rubber Hardness Tester is widely used in the rubber industry to evaluate this important property. The Presto IRHD (International Rubber Hardness Degrees) tester is equipped with a spherical indentor, which indents the sample under a minor and major Load. The differential indentation depth is measured and tabulated to read directly in ‘IRHD’ degrees.

IRHD or Rubber hardness tester helps to find out the hardness of rubber and its components. Hardness is one of the most significant properties which conclude the aptness of any component. Incorrect hardness may defeat the basic purpose for which the component is designed. Hence, accurate and reliable determination of the hardness is extremely important in the rubber industry. Presto’s IRHD tester is mainly used to evaluate this important property. Owing to the supreme quality, these testers are exported to various international markets.
