adidas has been producing high-performance igniter balls since 1963 and is the concern's directive football producer. Still, it took adidas comfortably over tierce geezerhood of voluminous research and processing to allocate the adidas Jabulani, its best-performing shot e'er. Thanks to a revolutionary Hairpin 'n' Channel saliency and a totally new 3D panel form, the freshly formulated Friction 'n' Impression profile provides the superfine players in the humanity with a clump allowing an exceptionally unchanging decorate and perfect grasp low all conditions. The players can now simulation their align.
The adidas Design Unit (a.i.t) has rigorously reliable the new Equalize Glob for the 2010 FIFA Humanity Cup Southeast Africa, no. low the toughest laboratory conditions likely, ulterior also with adult players and clubs on the tract of activity. Scientific tests were conducted together with the Sports Engineering Explore Unit of the University of Loughborough, one of the slip institutions of its category worldwide.

Tests executed in the adidas football laboratory in Scheinfeld and at the Investigation Displace of the Lincoln of Loughborough corroborate the adidas Jabulani does not exclusive cope these FIFA-Approved standards, it exceeds practically apiece of them.
Circumference Test
A consistent circumference is important to allow optimal control during dribbling or driving a football. In order to calculate the average circumference, each individual match ball is measured at 10 different points.
- FIFA-Approved Standard: 68.5 cm - 69.5 cm
- adidas Jabulani: 69,0 cm (+/- 0,2 cm)
Permanent Roundness Test
Exclusive a utterly assault globe allows a contestant to fully provide on his skills. The many perfect the domain is, the solon counterbalanced a sphere gift be in adorn, the higher instrument be its truth and the predictability of its beautify. The new 3D panel shape harmonizes the vim movement and minimizes the amount of corners, time the larger panels let for a tradesman motion atlantic. The diameter of the comedienne is metrical in 16 diverse places, after which the number is calculated. The conflict between the highest and the worst diameter must be within real unpermissive limits.
- FIFA-Approved Standard: Maximum 1.5% difference
- adidas Jabulani: Maximum 1.0% difference
Water Absorption Test
A wet and soggy comedienne behaves quite differently from a dry one. It flies through the air much easy, has a low leap and is author problematic to bend. adidas' patented Thermic Bonding technology makes a sport virtually waterproof. As a resultant the new Couple Clump shows completely homogenous performance characteristics when playing in dry or wet conditions. For the irrigate absorption tryout, the glob is pressed and rotated in a container of food 250 times, after which the masque give be weighed. The thing instrument also be weighed before and after the liquid uptake check.
- FIFA-Approved Standard: Water absorption: no more than 10% weight increase
- adidas Jabulani: Water absorption: 0% weight increase
Perfect Weight Test (420 to 445 grams)
Each professional game is played with a number of balls. These different balls all need to perform the same. Consistency in weight is crucial. If the ball is too light or too heavy, it might move unexpectedly in flight.
- FIFA-Approved Standard: Weight between 420 and 445 grams
- adidas Jabulani: Weight 440 grams (+/- 2 grams)
Shape and 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
- adidas Jabulani: 3,500 cycles at 50 km per hour
Drum Test

- FIFA-Approved Standard: No more than 10 cm
- adidas Jabulani: 143 cm measured at 20°C
Loss of Pressure Test
If the ball loses air during the game, it will be difficult to predict and may not respond consistently, making long passes and deep crosses almost impossible. For this test, the ball is inflated fully and three days later its air pressure is measured. It must not have lost more than a specified percentage of its air.
- FIFA-Approved Standard: Loss of pressure maximum 20%
- adidas Jabulani: Loss of pressure maximum 10%
