Shock Absorption (KA):
Shock absorption or force reduction is the ability of a sports floor to absorb the shock of an impact. The athlete must not be exposed to more than 47% of the impact when compared to a non-resilient floor.
Standard Deformation (StVv):
Standard deformation or resilience defines the vertical deflection of the sports floor under load. The minimum deflection required is 2,3 mm.
Deformation Control (W500):
Deformation control is a floor’s ability to control the area spread of a deformation. It is measured in a distance of 500 mm from the point of vertical impact (by a falling weight of 20 kg). The maximum deformation must not be higher than 15%.
Ball Rebound (BR):
Ball rebound defines the height in % terms a basketball bounces on an area-elastic sports floor, when compared to the ball rebound on a non-resilient floor. The ball rebound must be at least 90%.
Friction (GV):
The friction test determines the properties of a sports floor surface with regards to quick turns by the athlete and the prevention of uncontrolled sliding. The sliding distance required is 0,4 to 0,6 m.
Behaviour Under Rolling Load (VRL):
This test shows the ability of an area-elastic sports floor to withstand loads from seating areas/bleachers, portable basketball goals or transport carts for aerobic mats. Minimum requirement: the sports flooring should
withstand a load per axle of 1500 N without damage.
