More Information
Model Code	8576135
Gender	UNISEX ALL AGES
Color	NEON YELLOW
Description	We developed this F500 hybrid ball for footballers that play in clubs and need a comfortable and durable ball.
weight	Between 420 and 445g (Size 5)
circumference	Between 68.5 and 69.5g (Size 5)
Sphercity	Average measured variation: maximum 1.5%. We measure the football's sphericity at 16 different points and examine the recorded discrepancies. If the discrepancy is greater than 1.5% (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.
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 15% of its weight, or approx. 60 g for this F500 in size 5.
bounce	Between 135 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 meters in height
shape and pressure retention	The most stringent test we put this ball through is the shooting machine 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: it must not have increased by more than 1.5 cm - the sphericity: it must not have varied by over 1.5% - the pressure: the ball's loss of pressure must not exceed 0.1 bar
