Reboundhas been exhaustively tested by Dr. Vaughan Thomas of Liverpool Polytechnic.
1. In one test, sample panels of three wall surfaces: Rebound, a "control" substance; and a special wall of a competitive manufacturer were each subjected to 25,000 impacts which was calculated to be equivalent to a period of over fifty ears of actual play. Each impact simulated mechanically the force of a full driven squash ball traveling at 35 meters per second and impacting at an energy of 290 joules per square meter. The "control" sample disintegrated over a period of several "laboratory" years and the competitive product gradually crazed, but at the end of the test Rebound was free from damage.
THE MAIN TEST CONCLUSIONS WERE:
1.1. The surface shows complete freedom from damage caused to normal squash court walls by impacts from hard objects such as rackets. 1.2. The surface appears to be virtually indestructible by squash ball impacts.
1.3. Tests of actual play, and stresses created by faults in the sub-surface rendering, demonstrate the very great resistance of Rebound to such wear and tear. When correctly applied, it appears to be almost indestructible by normal squash court stresses.
2. Further tests were carried out by Pilkington Brothers PLC at their research and development laboratories in Ormskirk, Lancashire.
COMPARATIVE TESTS
Two identical brick walls were rendered respectively with Rebound and a plaster-based material and tests were commenced after a 28 day air cure.
TEST ONE
A steel ball weighing 1.825kg(4lb) diameter 76mm (3in) was dropped onto the surface of each rendering from a series of different heights and maximum indentation resulting from each drop was measured.
RESULT
TEST TWO
The same steel ball was dropped a number of times onto the same spot of each surface from a height of 1250mm and the resulting indentation measured. To ensure impact on the same spot, each cycle of drops was made through an accurately positioned tube.
RESULT
After 15 impacts radical cracks had appeared in the plaster-based material and became progressively worse with successive impacts. The Rebound surface was free of cracks at the conclusion of the test.
