The World Cup is a wonderful experience for a lot of people! Millions of eyes are focused on television and thousands watching it live on football stadium. However, this may not be possible without the World cup Adidas ball! Every 4 years was selected ball, which will be the face of the tournament. It must meet many criteria that are set by FIFA. Goes through various tests and if passes all the tests shall be declared as the new cup Adidas ball!
Producer company itself has created a laboratory for quality control called the Adidas Innovation Team or AIT. Following the testing of these candidate World cup Adidas ball is given to professional football players to be tested directly on the football pitch. In University of Loughborough is the world leading institution - Sport Technology Research Group. It also made many tests and studies. Everything proves that World cup Adidas ball is the only nominee and winner. Most round, most stable flight and the best behavior among competitors.
The best players from the tournament can show its superb quality thanks to FIFA and the high quality criteria that are created. Tests made at the World cup Adidas ball all outperform the benchmarks. And some of them are: Loss of Pressure Test, Drum Test, Permanent Roundness Test.
Loss of Pressure Test: The loss of air from the World cup Adidas ball during the game can lead to unpredictable and difficult to control. Making passes and sprint can become almost impossible. For this purpose, the test is done as follows: the ball is fully inflated, and after 3 days the pressure is measured in. There should be no more loss rate than anticipated.
* FIFA-Approved Standard: Loss of pressure maximum 20%
* Adidas Jabulani: Loss of pressure maximum 10%
Drum Test: This test is specially designed by adidas in order to guarantee the durability and high-quality printing on the surface, the species and unique design. In the same way as the Teamgeist, World cup Adidas ball Jabulani owns the underglass print technology, providing the best and most robust surface material that ensures the retention of the unique nature and strength as much as possible any longer!
Permanent Roundness Test: To show what A footballer is able to pitch, the ball must be perfectly round. If it is perfectly round, in which case it is much more balanced in their fields, more precise and predictable with each stroke while flying in the air. The shape of the new 3-D panels contribute to the harmonization of energy shift and minimizing the amount of formation of angles. A good hit is possible due to the larger panels. To make this test, World cup Adidas ball was measured at 16 different points and calculate the average diameter. A difference between the smallest and largest diameter must be set in advance limits.
* FIFA-Approved Standard: Maximum 1.5% difference
* Adidas Jabulani: Maximum 1.0% difference.
