Tensile strength and elongation are the two prime characteristics of most of the raw materials, whether they are metals: or non-metals: such as foam, rubber, textiles, plastic, paper: or finished products such as rods, wires, ropes, yarns, belts etcetera. These properties very often play the major role in determining the suitability of any raw material for any specific application. It is therefore, of utmost importance to determine these characteristics accurately, conveniently, and quickly.

Tensile Testing Machine provides a relatively inexpensive way for determining the tensile strength and elongation of variety of raw materials such as rubber, leather, fabric, plastics, Belts, wires etcetera. They are based on constant rate of traverse principle in which one end of the test specimen is held in a stationary grip, while the other end is made to move at a known fixed speed with the help of motor, gearbox and screw arrangement. The load exerted on the stationary grip is sensed by a load cell and indicated by a digital load indicator. The controller is microprocessor based and has the facility of over load protection, peak hold and auto calibration. The load directly indicated in kilograms or Newton.

The elongation of the test specimen is measured on a digital indicator fixed on the frame of the tester, which indicates the distance between the grips. The frame of the tester fabricated from heavy mild steel sections to give the required rigidity and strength. Various built in safety arrangements such as over travel protection are provided.

The tester is finished in metallic painting and bright chrome| zinc plating to give the apparatus a corrosion resistant finish. It is supplied complied which electrical. Which include micro-, switches, Push buttons, and contactors for safe and convenient operation.

In Din method of determine abrasion resistance of vulcanized natural or synthetic, a cylindrical rubber test specimen is abraded against an abrasive surface mounted on a rotating cylindrical drum in such a manner that abrasion takes place on one of the flat ends of the test specimen which is held against the abrasive surface under a specified load while being traversed across it. The ratio of the volume loss of a standard rubber to the volume loss of the test rubber measured under the same conditions, expressed as a percentage, gives the abrasion resistance index of the rubber under test.

Din Abrasion Tester is designed to determine abrasion resistance index of natural and synthetic rubber in accordance with the above principle. It consists of test specimen holder with a cylindrical opening adjustable between 15.5 to 16.3 mm to clamp the test specimen with an arrangement to adjust the length of test specimen protruding out. The holder is mounted by a screw mechanism along a length of a rotating drum on which the abrasive cloth is fixed. The movement to the screw mechanism and drum is given by an electric motor, gearbox and chain mechanism to give the specified speed of rotation to the drum and the specified lateral movement to the test specimen holder. The swivel arm and test specimen holder are so disposed that the test specimen is pressed against the drum under the specified load with its centre axis at an inclination of 3 degree to the perpendicular in the direction of rotation and placed above the longitudinal axis of drum. A rack and pinion arrangement to rotate the test specimen about its axis during the test (whenever desired) is also provided.

The abrasive cloth is firmly fixed to the drum using a suitable peel able adhesive with the ends of the abrasive cloth butt jointed together. The equipment is provided with limit switches which, in addition of giving over travel safety to the movement of test holder by preventing the lower edge of the test specimen holder to touch the abrasive cloth.

The equipment is built on rigid steel base and finished in grey metallic and bright chrome / zinc plating to give it a corrosion resistant finish. Moulding die, rotary type cutting die(hollow drill) for preparing test specimens and extra abrasive cloth are available as optional accessories.

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.

The strength of adhesion of sole of a shoe to its upper is determined by measuring the force needed to pull off the sole from the upper. A suitable last is placed inside the shoe which is then placed on a straight edge acting as a fulcrum for applying load on the joint of the sole and upper. The maximum load the sole is able to withstand before coming off is determined and reported as the sole adhesion strength. This test can be carried out either at the heel or at the toe of the shoe. 

Sole Adhesion Tester consists of a load cell and digital indicator to indicate the load applied at the junction of the sole and the upper, a lever arrangement to transmit the load exerted on the toe piece to the spring dynamometer, a straight edge fulcrum for resting the shoe on during the test, and a set of interchangeable toe pieces having different curvature. 

The load indicator indicate the load applied on the joint directly in kilograms, taking into account the mechanical advantage of the lever transmitting the force from the toe piece to it. The indicator has the facility of peak hold and tare. 

There is an screw arrangement to hold the shoe with last and have the arrangement to up and down movement (load application to the shoe) with the help of the motor, gear box, and screw arrangement.

The toe piece are five in number and having different curvature to enable toes and heels of different shapes and sizes to be tested. The length of arc of each toe piece, however, is the same to ensure that the load is applied only on a fixed length of joint. They are made from carbon steel for giving a long operational life. Any one of the toe pieces can be held in the equipment at one time.

The fulcrum on which the shoe is placed during the test has adjustable height to enable soles of different thickness to be tested. The height of the fulcrum is adjusted with the help of spacer strips provided with the instrument.

The instrument is finished in painting and bright chrome plating to give it a corrosion resistant finish.
