France Football - Size 5 2022

We have conducted numerous lab tests to guarantee the ball's ability to withstand every hit.

Between 68.5 and 69.5 cm (size 5)

Average measured variation: maximum 2%.We measure the football's sphericity at 16 different points and examine the recorded discrepancies.If the discrepancy is greater than 2% (FIFA PRO Standard), our engineers are tasked with improving the sphericity to ensure a consistent bounce.

We inflate the ball to the recommended pressure (meaning 0.8 bar).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.

We simulate rainy playing conditions in a lab, leaving the ball to sit in 2 cm of water on a pivoting support whilst subjecting it to 250 compressions.By the end of the test, the ball must not have absorbed more than 20% of its weight, or approx. 80 g for this ball in the French colours in size 5.

Between 420 and 445 g (size 5)

Between 125 and 155cm with a maximum difference of 10cm between the ball's highest and lowest bounce. Each ball is dropped 10 times on a steel plate from 2 metres in height.

The most demanding test that this ball is subjected to is the machine shot test.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.
