Artificial Grass Football Field Acceptance Criteria
1. Visual inspection of appearance.
1.The grass color is uniform, and the color of various functional lines and point lines is uniform and bright, and there is no color difference.
2.The appearance of the turf should be flat, with no obvious unevenness, and no obvious scattering of grass silk.
3.For the splicing, there should be no obvious height difference, and the grass silk should be tight and there should be no obvious gaps.
2. The width and positioning of each functional line and point line are accurate.
1.The size of the functional area is in line with the standard, and the line width error is within 1cm.
2.The point line should be accurately marked, and the error should be within 1cm.
3. The gap between the seams of the two turf strips does not exceed the specifications of the product.
1.The seam lines of the two turf should be straight, the bonding should be compact, and there should be no obvious joints.
2.For the splicing, there should be no obvious height difference, and the grass silk should be tight and there should be no obvious gaps.
4. The turf around the court should be cut flat and basically consistent with the foundation edge.
1.There must be no obvious unevenness or notch (except for problems due to uneven foundations).
2.There should be no obvious burrs and irregularities on the cutting surface.
5. The surface of the filled sand and rubber particles is clean, full of filling, and there is no obvious unevenness.
1.Sand and rubber particles should be fully filled and the surface should be flat.
2.There is no obvious unevenness to ensure the flatness of the football field.
6. The flatness and slope of the artificial grass football field.
1.The flatness should meet the filling requirements determined by the contract.
2.The slope should meet the standards set by FIFA.
7. The marking color and size of various functional lines and point lines shall meet the requirements of FIFA rules.
1.The error of the long side of the non-standard site is allowed to be within 1cm.
2.The error of the long side of the standard field is allowed to be within 2cm (all fields other than football fields must meet the requirements of the corresponding rules).
8. In order to meet the mechanical properties of the field and protect the sports personnel, the amount of auxiliary materials is: 25kg of quartz sand per square meter, 5kg per square meter of lawn filling rubber particles, and the specifications and quality standards of the auxiliary materials are as follows
1.Quartz sand: the particle material is excellent, the specification is 20-40 mesh, clean and dust-free;The particles are uniform and round, without sharp edges and corners, the surface is smooth and clean, and there are strong wear resistance and corrosion resistance. (Avoid abrasion of artificial grass products and reduce their service life.) ）
