The Nueno has passed rigorous testing to FIFA Quality Pro standard for:
– Circumference to check to ball is the perfect size
– Sphericity to check the ball is perfectly round
– Rebound properties at different temperatures so the ball remains optimum in any environment
– Ball weight between tight parameters
– Loss of pressure so the ball loses very little air over a long period of time
– Water absorption so the ball remains playable even in the wettest conditions
