FIFA BASIC F500 hybrid football size 5

It is by observing football players on their playground that our design team thought up and designed this Hybrid football. Hybrid because in the design of this ball we have mixed the comfort of a machine-stitched ball with the resistance of a hand-sewn balloon. In addition, we have chosen a specific bladder construction (2 km of threads that roll up the bladder) in order to guarantee you longer inflation and better sphericity.

This ball weighs between 410g and 450g (size 5) and meets official FIFA standards.FIFA BASIC approval.

The size of this ball is between 68,0cm and 70,0cm (size 5) and meets official FIFA standards.FIFA BASIC approval.

Here is the sphericity test: Variation of the average measured: maximum 1,8% (FIFA BASIC approval). We measure the sphericity of the ball at 4500 different points and look at the differences observed. FIFA BASIC standard), our engineers are on a mission to improve the sphericity to guarantee a regular rebound.

Here is the pressure loss test: We inflate the balloon to the recommended pressure (i.e. 0,8 bar). 72 hours later, the balloon must not have lost more than 15% of its pressure, i.e. approximately 0,1 bar (FIFA BASIC approval). The pressure after 72 hours should therefore be around 0,7 bar. This also means that it is completely normal for a balloon to lose pressure after a few days.

Here is the water absorption test: In the laboratory, we simulate playing conditions in the rain by soaking the ball in 2 cm of water on a pivoting support while applying 250 compressions. At the end of the test, the ball must not have gained more than 10% of its weight (FIFA BASIC approval).

Here is the rebound test: The ball is dropped 10 times on a steel plate from a height of 2 meters. The variation in the height of the rebounds must be between 125 and 155 cm with a maximum difference of 10 cm between the rebound on the highest and lowest bounce per ball.

The most demanding test we put this ball through is the machine shot test. test, we check:- the general condition of the ball: the seams must withstand this test- the circumference: it must not have increased by more than 2500 cm.- the sphericity: it must not have varied more 50% - the pressure: the ball must not have lost more than 2,5%
