The ball also participate in FIFA’s testing and certification program. The football world’s governing body uses seven lab tests to simulate match action and guarantee consistent performance.

TEST 1: CIRCUMFERENCE
The ball’s diameter is measured at 10 different points and the mean average is calculated. FIFA Approved balls (size 5) must measure 68.5-69.5 cm. Circumference must be consistent for predictable play.

TEST 2: ROUNDNESS
In this test, the diameter of the ball is measured at 16 points and the mean average is calculated.
The difference between the highest and lowest diameter must be no more than 1.5 percent for FIFA Approval. A slightly uneven seam can change the ball’s shape.

TEST 3: REBOUND
The ball is dropped 10 times onto a steel panel from a height of two meters. FIFA Approved balls must bounce between 120 – 165 cm. The difference between lowest and highest bounce must be no more than 10 cm.

TEST 4: WEIGHT
FIFA Approved balls must weigh between 420 – 445
grams.

TEST 5: WATER ABSORPTION
A machine turns and squeezes the ball in a tank of water 250 times. FIFA Approved balls must not absorb more than 10 percent in additional weight.

TEST 6: LOSS OF PRESSURE
In this test, the ball is inflated to 1.0 bar. In 72 hours, it must lose no more than 20 percent of air for FIFA Approval.
A ball which loses pressure during a game will perform erratically.

TEST 7: SHAPE & SIZE RETENTION
The ball is fired 2,000 times against a steel plate at 35 MPH. Seams and air valves must be undamaged. Pressure loss and changes in circumference must be minimal.
