Foam Testing Equipment measure firmness, strength, general properties, and stiffness. It is Fatigue life, resistance to impact, tensile adhesion, and tear resistance. This equipment determines the loss of indentation force deflection, loss of thickness & structural breakdown by visual assessment of polyurethane. We manufacture this product using supreme quality materials and the latest technology.
One of the methods used for determination of flammability of fabrics is the Inclined Plane Flammability Tester. In this method, a test specimen taken from the sample under test is held in a sheet metal holder at an inclination of 45°. A flame from a standard jet is made to impinge on the upper face of the fabric near its bottom edge and the time taken for it to propagate through a distance of 127 mm determined to evaluate the flammability of fabric sample under test.

In this test, a test specimen in shape of a square block is held over a flat reciprocating platform and is pressed down from top by a horizontal cylindrical roller inclined at an angle of 15° to the direction of motion of the platform. The platform is moved for a specified number of cycles and the effect of repeated compressions produced on the test specimen is evaluated by finding the change in its thickness and indentation hardness number.
Thickness of polyurethane foam products below 100 mm in thickness are measured by using a soft material thickness gauge having an arrangement to measure thickness with an indenter of specified area exerting a specified pressure on the test specimen whose thickness is being measured.
The Foam Thickness Gauge for polyurethane foam consists of a dial indicator mounted over a metallic frame and a circular indenter of specified diameter and weight to apply a specified pressure on the test specimen.

The Globe Ball Resilience Testerfor polyurethane foamconsists 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 effect of repeated application of pressure on the surface of a slab of polyurethane foam experienced in its normal life is evaluated by simulating these conditions in laboratory by applying and releasing a specified force for a specified number of times, after which the effect of such pounding on the physical characteristics such as hardness index, thickness, and cell structure are observed to evaluate the quality of foam slab.
The Globe Indentation Hardness Tester For Polyurethane Foam consists of a circular indentor which can be pressed against the foam block under test, a motorized arrangement to move the indentor up or down, and a load measuring and indicating arrangement to indicate the load being exerted by the indentor on the foam block at any instant.

The Globe Air Flow Tester for polyurethane foam consists of an arrangement to hold a test specimen in a square opening in a cylindrical chamber so as to expose a known area to the flow of air through it, a vacuum system to draw air through the exposed area of the test specimen, arrangement to measure the rate of flow of air through the test specimen, and arrangement to measure the pressure drop between the two faces of the test specimen as a result of flow of air
