Football Size 5 - Hungary 2024

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.
