Average measured variation: Maximum of 1.5%.
Maximum pressure loss
20% in 72 hours
15% (Test carried out in 2 cm of water with 250 compressions and constant rotation of the ball)
Between 135 and 155 cm with a maximum difference of 10 cm between the ball's highest and lowest bounce. Each ball is dropped 10 times on a steel plate from a height of 2 metres
Shape and pressure retention
Resists up to 2500 shots against an inclined concrete surface at 50 km/h at a distance of 2.5 m. Maximum 1.5 cm increase in circumference, maximum 1.5 % variation in sphericity and maximum 0.1 bar change in pressure.
