The soccer ball V2.0

Shape & size retention test

During an average game the ball is kicked approximately 2,000 times. However, in the last minute of overtime, the ball needs to perform identically to the way it did in the first minute of the game.

In order to test the shape and size retention, the ball is fired against a steel plate 2,000 times at 50 km per hour for the FIFA Approved hallmark. After this test, only minimal changes in air pressure and roundness are allowed and the air valve and stitching must remain undamaged.

FIFA Approved Standard: 2,000 cycles at 50 km per hour The adidas +Teamgeist: 3,500 cycles at 50 km per hour

Drum test

The drum test was developed by adidas to guarantee high quality and durability of the printed surface, the unique design and look of the ball. The adidas +Teamgeist is the first ball ever to feature a complete underglass print technology, providing the +Teamgeist with the best and strongest surface material ever and guaranteeing the ball is more durable and will hold its unique look much longer.

Uniform rebound test

Players need to be able to anticipate how the ball will respond in order to control a pass using their chest, thigh or foot. For this test, the ball is dropped ten times onto a steel plate from a height of 2 meters. The difference between the highest and the lowest bounce must be no more than 10 cm. FIFA Approved Standard: No more than 10 cm The adidas +Teamgeist: No more than 2 cm
