SynthetIc Grass

Bouncing of Ball: The test is carried out in such a way that the ball which bounces 135 cm height when dropped from 2 meters height to the concrete floor is bounced from 2 meters three times in 6 different points of the field. The ball should bounce 65-100 cm height for FIFA 1 Star and 65-85 height for FIFA 2 Star.

Ball Rolling: The distance of the ball which is dropped from 1 meter-height ball rolling ramp in 45 degree angle is determined. The test is carried out by rolling the ball three times from 6 different points of the field in the direction of the slope and in adverse direction. The rolling ball should stop in 4-10 meters for FIFA 1 Star and 4-8 meters for FIFA 2 Star.

Crampon twisting resistance In order not to get their ankles twisted during the play due to the floor , football players should have a certain resistance. This resistance is determined in N value by means of this test. This value should be 25-50 N for FIFA 1 Star and 30-45 N for FIFA 2 Star.

Shock Absorption Test: The softness of the floor should be in the determined standard in the activities such as running, falling, slipping etc. in order to avoid any injuries arising from the floor. During this test, floor shock absorption is measured three times in 21 different points and the convenience of the floor for football is determined. The floor should have 55-70% shock absorption for FIFA 1 Star and 60-70% for FIFA 2 Star.

Vertical Deformation: Measuring the deformation arising from the activities of the football player in the field and its being within the standard values are the indications that the synthetic grass field will be used for years. The deformation test carried out in 21 points three times is the proof of which the field will show resistance to football player's deformation during the validity period of the document. Deformation value should be 4-11 mm for FIFA 1 Star and 4-10 mm for FIFA 2 Star.
