Equipment

All testing devices required to conduct a tournament must be approved by the BISFed Technical Delegate and or Head Referee of each sanctioned event.

The ball must be allowed to roll under its own weight down a 290mm ramp consisting of a pair of aluminium bars centred 50mm apart. The ramp will be set at 25 degrees to the horizontal. When the ball exits the ramp, it must travel at least 175 mm in a straight line along the exit plate. A ball will pass if it exits the device on at least one of three attempts by falling off the exit plate.

The circumference of the ball should be 270 mm +/- 8mm and will be tested using a BISFed STANDARD template (of thickness 7 – 7.5mm) which contains two holes: one hole with a circumference of 262mm and one with a circumference of 278mm.

The weight of the ball should be 275 g. +/- 12 g. Each ball will be tested using a scale accurate to within 0.01g.
