EVALUATION AND TESTING


 AOK commenced its Swiss ball development and testing program in 1996. The University of Newcastle was
 selected because of its international reputation in materials testing. Testing protocols have been developed
 which are considered the best in the world for inflatable PVC products.



 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
 accidently 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.
