When constructing basketball courts (including acrylic basketball courts, hard acrylic basketball courts, elastic acrylic basketball courts, basketball courts, plastic basketball courts, silicone PU basketball courts, basketball court construction, basketball court flooring materials, artificial grass basketball courts), the court area should be 28×15m (including the auxiliary court at 32×18m), with an additional surrounding area, totaling 32.1×22.1m or 18m (18m being the narrower width). Such a court can accommodate various local-level competitions. If utilizing existing courts for domestic competitions of various levels, the length and width can be slightly smaller than standard, but not excessively; the length can be reduced by 4m and the width by 2m, while maintaining a proportional reduction (2:1) in both dimensions (e.g., the total area can be reduced to 26×14m). According to the revised rules of the European Basketball League, for a 26×14m court, if the hoop and supports are fixed, the court width can be expanded to 15m while maintaining the length. At least a 2m area must be left outside the main basketball court area, free of any obstructions. This area starts from the outer edge of the court boundaries. This regulation does not apply when the court is used for informal games or recreational purposes. (Mini basketball courts are 28×15m, with a distance of only 4m between the service line and the backboard, marked similarly to a standard court, but with a smaller backboard.)
Scope
This standard sets forth the technical requirements and testing methods for the plastic surface of basketball courts.
Inspection, Usage, and Maintenance Guidelines.
This standard applies to the polyurethane surface layer of sports courts laid with polyurethane as the main material.

3. Test Methods
The determination of elongation properties was conducted according to the methods specified in GB/T528-1992, utilizing Type I cutting blades.
The tensile strength test was conducted in accordance with the methods outlined in GB/T529-1991, utilizing a right-angled cutter.
The flame retardancy test is conducted in accordance with the methods specified in GB/T 14833-1993.
(4) The measurement of tennis elasticity coefficient is conducted according to the method specified in Appendix A (Supplementary Material).
