The Ball Resilience Tester for polyurethane foam consists of a flat horizontal platform, a vertical acrylic tube in which the sphere is dropped, and a hand operated arrangement to release the sphere from a pre-determined height.

                The platform on which the test specimen is kept also forms the base of the equipment. It has four leveling screws to make it horizontal.

                The acrylic tube is held over the base with the help of a holding block, which can be moved vertically to adjust the height of the tube to enable test specimens of different thicknesses to be tested. This adjustment is carried out with the help of a screw so that the height of the tube can be precisely set. The tube is held firmly after adjustment so that it does not rock during the test.

                The scale used for measurement of the height of rebound is marked on the outer surface of the acrylic tube. It ranges from 10% to 90% of the dropping height.

                The metallic sphere is kept in a circular opening in the metallic cover of the acrylic tube. It can be release by pressing a spring-loaded support, which is so designed as to release the sphere without imparting any initial linear or rotary movement to it.

The Shear Fatigue Tester for polyurethane foam consists of a reciprocating platform on which the test specimen can be held, a cylindrical roller to compress the test specimen, and an arrangement to either produce a constant deflection of the test specimen or to apply a constant load on it.

The reciprocating platform is made of cast aluminum and is moved in a horizontal plane with the help of a motor, worm reduction gearbox, and a link. It moves on four wheels having ball bearings. The wheels run on two metallic rails. The platform has a large number of holes on its upper surface for rapid escape of air during compression. The test specimen is held on the platform with the help of either a double-sided adhesive tape or by holding fabric strips pasted on its ends under two bar shaped grips.

The cylindrical roller is made of stainless steel and rests on the surface of the test specimen. Its axis is inclined at 15° to the direction of motion of the platform. The roller is mounted on two ball bearings and is held on the ends of two levers to permit a hinged vertical movement.

The desired deflection is given by placing dead weights above the cylindrical roller. Test under constant deflection are conducted by restricting the vertical movement of the roller with the help of two adjustable knurled bolts. Tests under constant load are conducted by placing desired dead weights above the roller.

A five digit pre-set type electronic counter with non-volatile memory is provided to record the number of compression of the test specimen and to automatically stop the motor after the desired number of compressions.

The apparatus is finished in blue metallic painting and bright chrome / zinc plating to give it a corrosion resistant finish.
