Bursting strength tester of any material such as fabric, leather, paper etc. Its strength under multi- directional force and is defined, as the hydrostatic pressure required producing rapture of the material when pressure is applied at a controlled increasing rate through a rubber diaphragm.

The ASIAN Bursting Strength Tester is designed to find bursting strength of fabric/leather/paper/paper board. A test specimen is held between two annular clamps under sufficient pressure to minimize slippage. The upper clamping surface which is in contact with the test specimens has a continuous spiral grooves. A circular diaphragm of pure gum rubber is clamped between the lower clamping plate & pressure cylinder so that before the diaphragm is stretched by pressure underneath it the center of its upper surface is below the plane of the clamping surface.

The equipment is fitted with a motor driven cam mechanism, which increases fluid displacement on the lower side of the diaphragm at a specified rate. The equipment is fitted with an arrangement, which automatically brings down the pressure and stops the motor on completion of the test cycle. A maximum reading type digital pressure gauge gives the bursting pressure.

The equipment is raggedly designed to give a long & trouble free life. The components are brighter chrome plated or painted in metallic paint to give the tester an aesthetic appearance.

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.

The ASIAN 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 center 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.

By rotating the specimen holder rod, the burning specimen can be quenched in a shallow pan of water positioned below the specimen holder.
• The specimen is ignited by a propane flame from a burner operating at a specified pressure. The fuel is mixed with air which has been propelled through the burner by the venturi effect of the propane as it passes from small orifice.  The burner is designed to provide adequate outside air. the burner is capable of being positioned quickly under the specimen so that the exit of the burner falls on a line passing through  a point 8mm  above the base at one corner of the chamber extending diagonally across the chamber and sloping up wards at 45 deg with the base. There is a control panel which control and indicate the supply of gas. Lux of light measurement system of the mounted light source also mounted in the instrument. There is a digital timer mounted in the instrument to indicate the time.

Oxygen index is defined as minimum concentration of oxygen, expressed as volume percent in a mixture of oxygen and nitrogen that just support flaming combustion of plastic materials under equilibrium condition of candle like burning. The equilibrium is established by the relation between the net lost to the surroundings as measured by either time of burning or length of specimen burned. This point is approached from both sides of the critical oxygen concentration in order to establish the oxygen index.

The “ASIAN” Limited Oxygen Index Apparatus consist of a test chimney made of borosilicate glass (size is 76mm internal diameter & 450mm long) suppurated by the metallic base and hook with the help of the metallic pillar.
