The ability of any shoe sole to withstand repeated bending experienced during walking without developing a crack within the estimated life span of the shoe is a very important factor for determining its quality. Also, its ability to withstand propagation of any slit formed due to a sharp edge or pointed object during walking is equally important in assessing its quality. These abilities of any sole can be evaluated with the help of a Ross Flex Tester.

Hardness Testers

A.I R H D Hardness tester
Hardness is one of the most important properties which determine the suitability of any rubber component for its intended end use. Incorrect hardness may defeat the basic purpose for which the component is designed. Thus accurate and reliable determination of hardness is of extreme importance in rubber field. Amongst the various means for the determination of rubber hardness the most important ones are the Durometer and the IRHD Hardness Tester. While the first uses the principle of indentation of a truncated cone in rubber under varying loads acting through a spring, the second method uses a fixed dead load acting on a hemispherical indenting tip. Whereas the first method suffers from the disadvantage of permanent set getting developed in the spring and thus affecting its accuracy, the second method, being based on dead load principle, is free from this problem.

Thickness gauges (neck depth-50 mm)

A.Bench type (10 mm range)3000.00ench type (25 mm range)
determination of thickness of rubber is of considerable importance, both for assuring conformity with design parameters, and for evaluation of various physical properties. Determination of thickness of rubber samples in laboratory is usually carried out with the help of a bench thickness gauge. The rubber component or test slab whose thickness is to be determined is kept on a flat anvil and a circular indentor is pressed onto it from the top under a specified pressure. The contact faces of the anvil and the indentor are ground flat and set in planes parallel to each other.

For conducting tests on various materials or products, test specimens of specified shapes and size are to be cut out of the test samples. Test specimens of rubber, leathers, fabrics, foam, flexible / semi-rigid plastics and similar other materials are usually cut with the help of knife edged dies of appropriate shapes and dimensions. The test sample / slab is placed over a flat and smooth piece of plywood, hardwood, rigid plastic, or hard rubber (ebonite) while the cutting die is pressed down from the top to cut out the test specimens.

Tension Set Apparatus (Model B)

Tension set is defined as the proportion of applied strain remaining after a rubber piece has been stretched and allowed to recover in specified manner. It is an important property for rubber components that are subjected to tensile stresses either continuously or intermittently. Tension set is determined by stretching a test specimen of standard dimension by a specified percentage in a suitable apparatus for a specified time and temperature and then allowing it to recover. It is indicated as permanent set retained by the test specimen expressed as a percentage of initial strain given to it.
