We designed this F500 Light ball for use by children. It is lighter, making it easier for children to learn to play, whether recreationally or at a club.
Learning to kick a ball and get it off the ground is not as easy as it looks. That's why we created this ball, which is 15% lighter than traditional balls.
DESIGN
LIGHTER THAN A REGULAR BALL
CIRCUMFERENCE
SPHERICITY
If the difference is greater than 1.5% (FIFA Pro Standard), our engineers are tasked with improving the sphericity to guarantee consistent bounce.
MAXIMUM PRESSURE LOSS
72 hours later, the ball must not lose more than 15% of its pressure, meaning approx. 0.1 bar. The pressure after 72 hours must, therefore, be at approx. 0.7 bar.
This also means that it is quite normal for a ball to lose pressure after a few days.
MAXIMUM WATER ABSORPTION
By the end of the test, the ball must not have absorbed more than 15% of its weight, which in the case of this F500 Light Size 5 is approx. 50 g.
BOUNCE
SHAPE AND PRESSURE RETENTION
Withstands up to 2500 shots against an inclined concrete surface at 50 km/h at a distance of 2.5 m.
At the end of the test, we check:
- the ball's general state: stitching must withstand this test
- the circumference: must not have increased by more than 1.5 cm.
- the sphericity: it must not have varied by over 1.5%
- the pressure: loss of pressure must not exceed 0.1 bar.
