Durability - Resists up to 2500 shots against an inclined flat surface at 50 km/h (laboratory tested). Bounce - 32 panels with 2 laminate layers combined with a latex / butyl bladder. Lasting air retention - Latex bladder. Design: We have conducted numerous lab tests to guarantee the ball's ability to withstand every hit. .Circumference: Between 68.5 and 69.5 cm (Size 5).Sphericity: 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. Maximum pressure loss: 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. Maximum water absorption: 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. Weight: Between 420 and 445 g (Size 5).Bounce: Between 125 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 2 metres in height. Shape and pressure retention: The most demanding test that this ball is subjected to is the machine shot test. Resists up to 2500 shots against an elevated flat 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.
