Product Description
Static pressure testing -- No mutations occurs after time 1 hour under 700kgs pressure (approx 1500Lbs). When shopping around for an exercise ball, note that what many of other companies balls are slim & light weight, indicative of inferior quality.
Dynamic durability testing - No mutations occurs after 20,000 loading cycles of an elastic load of 130kgs (approx. 260LB), this is a destructive testing. We state 260LB instead of 1500Lbs in the package box, to avoid extreme destructive testing or using by few customers.
