Ball Resilience Tester For Testing Lab Workshop.
Ball Resilience Tester - For Testing Lab
Resilience of polyurethane foam is determined by dropping a metallic
sphere on a slab of foam kept on a horizontal surface from a height of
500 mm and finding the height to which it rebounds after striking the
surface of foam.
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.
