What is “Anti-Burst”?
Not all balls are created equal! It is very important to use a high quality ball product that is actually “anti-burst” such as the DuraBall Pro Swiss Ball. This particular brand has been tested by the University of Newcastle engineering department, and if a puncture occurs, it will deflate slowly rather than burst. It is still possible for a Dura Ball to get punctured, but the injury risk is much lower.
The DuraBall Pro Swiss Ball is tested in a specially designed apparatus, which can progressively load a ball with a series of free weight. The test ball is then punctured with a very sharp, 10mm knife blade. A ball is deemed to be anti burst when the cut in the ball does not expand from the size of the cut made by the blade. The manufacturer’s tests on the DuraBall Pro have exceeded a 500kg burst resistance rating. This means that if you applied a dynamic load of 500kg to the ball and it suffered a puncture of any kind, it will deflate slowly. This gives a margin of safety to prevent injury in any use of the ball.
