For the acceptance criteria of the silicon PU stadium, here are some common requirements and guidance:
1.Flatness: The surface of the court should be flat, and there should be no obvious waves, bumps and other problems. Measure with a ruler or flatness meter to ensure the flatness of the pitch surface meets the requirements.
2.Elasticity: The surface of the pitch should be appropriately elastic to provide the right amount of force to reduce the risk of injury to the athlete. It can be tested by using a professional elasticity testing instrument to ensure that the silicon PU layer is elastic enough.
3.Hardness: The hardness of the surface of the court should meet the requirements of the relevant standards. It can be tested by a hardness testing instrument to ensure that the hardness of the silicon PU layer is within the proper range.
4.Bonding strength: The bonding strength between the silicon PU layer and the base layer should meet the requirements to ensure that the surface layer of the court is not easy to fall off or crack. Bond strength tests can be performed to evaluate bond performance.
5.Slip resistance: The surface of the court should have good slip resistance to ensure that athletes are not easy to slip during the game. The slip resistance of the pitch surface can be assessed by the coefficient of friction test.
6.Weather resistance: The stadium material should have good weather resistance and be able to resist the influence of natural environments such as sun, rain, freeze-thaw. Weathering tests can be performed to evaluate the durability of the material.
7.Color and lines: The color of the surface of the course should be uniform and bright, and the lines should be clear and standardized. Make sure the pitch presents a good visual effect for easy play and training.
These are some of the common acceptance criteria for silicon PU stadiums, and the specific requirements may vary depending on the region, the environment in which it is used, and the purpose of use. During the acceptance process, the evaluation should be carried out in accordance with the relevant standards and specifications, and laboratory tests and on-site tests can be carried out with the help of professional testing institutions.
