1.introductions
The coefficient of restitution measuring device for ceramic tiles is to determine the impact resistance of ceramic tiles by measuring the restitution coefficient. During testing ,a steel ball with diameter of 19mm is falling at a height of 1 meter to impact the test sample, and then measure the rebound height of the steel ball to get the restitution coefficient of ceramic tiles. The rebound height and restitution coefficient can be get by one test without calculation.
