Circumference (TEST 1) and Roundness (TEST 2) are both measured in 45000 points on the ball's surface, Rebound (TEST 3) is split into two sub-tests in two different temperature and humidity conditions (see TEST 3A and 3B). The ball is put through a cycle of 10 drops from the high of 2 meters on a steel plate for each sub-test. Water Absorbtion (TEST 5) testing is conducted within a cycle of permanent tourns and squeezes of the ball in a tank of water. The tested for IMS badge football is checked after 250 squeezes and is not allowed to take more water than 10% of the original weight. Minimal Pressure Loss (TEST 6) starts with inflation with compressed air to a pressure of 0.8 ± 0.005 bar and is based on a check after 72hrs period.
