Football test - Minimal pressure loss

Pressure in a football must remain consistent throughout a match. If it does not, the ball must be pumped up again as soon as possible. That might be entertaining, but it would certainly disrupt the flow of the game.
In the laboratory, the ball is inflated to standard pressure. After 72 hours it must not have lost a certain percentage of its air if it is to meet the definitions of either the FIFA APPROVED or the FIFA INSPECTED quality label.
