We state 260LB in the packge box, to avoid extreme destructive using by few customers.* Anti-burst testing -- The ball is loaded, then on the maximal lateral extent a pointy object (e.g. a pin or tack) with diamter 1.5mm is driven into the ball with a force of 750N and then removed. Afterwards, the ball is loaded 20times with 750N. Interval:15 cycles per minute. No sudden explosive breakage occur,the air exit the ball slowly. FAQs: Q1: The nozzle doesn't fit, I can't use the pump. A: The inserted white plug (air stopper) on the ball must be removed first! Inflation Instruction: Step 1: Take out the inserted white plug (air stopper) from the ball.Step 2: Insert the tip of the pump into the mouth (built-in variable aperture).Step 3: Pumping the ball to proper size (usually 10 minutes for a 75cm ball). Step 4: Quickly replace the white plug back into the hole to stop air leak. Done and Enjoy! Q2: Ball size is smaller than advertised.A: Ball is made of rubber which will become much contracted being packed tightly into the box. Thus, keep pumping to stretch the rubber is the key. If it is hard to reach suggested ball size during 1st inflation, users can leave the ball as it is for a day, and then pump again after the PVC material gets fully stretched.
Technical Details
- 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 duribiity 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 1000Lbs in the package box, to warning extreme destructive testing or using by few customers.
- Anti-burst testing -- The ball is loaded, then, on the maximal lateral extent a pointy object (e.g. a pin or tack) with diamter 1.5mm is driven into the ball with a force of 750N and then removed. Afterwards, the ball is loaded 20times with 750N. Interval:15 cycles per minute. No sudden explosive breakage occur, i.e. air exit the ball slowly.
