Playing football on synthetic turf football fields is now as enjoyable and quality as natural grass. Due to the high maintenance costs of natural turf pitches and the lack of frequent matches, synthetic turf pitches are preferred.
Since there is no corrugation on the surface of a field with FIFA Recommended certification, shock absorption is standard, the synthetic turf used will not shed and discolor in a short time, and the soccer ball will not move out of the standard to affect the player's game.
The tests and criteria of FIFA Recommended certified football fields are as follows, respectively.
The synthetic turf manufacturer with FIFA license will use the synthetic turf system that will be used in the football field before applying it to the field; By having one of the laboratories accredited by FIFA tested according to FQC (FIFA QUALITY CONCEPT) standards, it has been defined that the system is in FQC norms.
The field, which passed the infrastructure conformity (corrugation) test successfully, is "suitable for laying process" by the laboratory accredited to FIFA. After receiving the certificate, after the shock pad is laid under the carpet, the synthetic turf laying process is started. After the synthetic grass joints are bonded with the helmet cloth, the amount and structure of the fillers in the laboratory tests accredited by FIFA are applied to the field with the help of a spreading machine.
4 steps to a FIFA-recommended football turf pitch
Ball Jumping: The test is done by bouncing the ball that bounces 135 cm when dropped on the concrete floor from a height of 2 meters, 3 times at 6 different points of the field from 2 meters. The ball should jump between 65-100cm for FIFA 1 Star and 65-85cm for FIFA 2 Star.
Ball Roll: The distance traveled by the ball dropped from the ball rolling ramp from a height of 1 meter at an angle of 45 degrees. The test is done by rolling 3 times in the direction of the slope and in the opposite direction from 6 different points of the field. For FIFA 1 Star, the rolling ball should stand at a range of 4-8 meters for a FIFA 2 Star of 4-10 meters.
Crampon Rotation Resistance: The floor must have the ability to show a certain resistance in order for the players to avoid ankle sprains caused by the ground during the game. With this test, the value of this resistance in N is measured. The FIFA 1 Star must be 25-50 N, and the FIFA 2 Star value must be 30-45 N.
Shock Absorption Test: The softness of the ground must be at the specified standard in activities such as running, falling, and slipping in order to prevent ground-related injuries. During this test, the ground shock absorption is measured 3 times at 21 points and the suitability of the ground for the football game is determined. 55-70% shock absorption for the ground FIFA 1 Star, 60-70% for FIFA 2 star.
