Since then mediBall®, MaxBall™ and DuraBall™ have been tested to ensure product consistency and evaluate new manufacturing protocols. These Swiss Balls have variously supported static loads well in excess of 4,000 kilograms with burst-resistance to a load of 500 kg. This does not mean “puncture proof” but protects you from explosive deflation. Burst resistance means AOK Swiss balls are designed to take approx 30 secs to deflate if accidentally punctured. We also test for deflation under load and durability. No Swiss, Therapy or Exercise Ball is 100% safe as it is not possible to test every single ball. By having an ongoing Quality program in place AOK endeavours to reduce the risk of ball failure. We pre-inflate and inspect every ball we make and have achieved exceptionally low numbers of faulty balls. |
Over the past 5 years we have had a
return rate of less than 0.2% - this compares with 10%-15% of some European and Asian balls. It is critical that the user care for the balls they use - much like maintaining a car tyre. The more hours of use and abuse it gets - the shorter its life. This is especially so in a commercial environment where there is little supervision this may be reduced to 3 months or less. This is result of the balls being kicked around and striking sharp edges, which damages the inner surface of the skin - not always apparent from the outside. These leave resulting fracture lines which may totally reduce its burst resistant qualities. Related Articles Duralon Technical Bulletin |
