1 Scope

China's national standard for synthetic basketball court surfaces at primary and middle schools. It is the companion to the track and field standard and shares its origin in the contaminated school surfaces of the mid-2010s, and its requirements are built on the same two pillars: what the surface must be made of and what it may emit, tested both on the material and on the installed court. The performance requirements differ from a running track's because the sport does. A basketball surface is judged on ball rebound, which must be consistent across the court and close to that of a hard floor; on slip resistance, which has to be enough to allow a sudden stop and not so much that a pivot tears a knee; and on shock absorption, which protects joints during repeated landings. Those three trade against one another, which is why they are specified together rather than individually.

This document gives the classification of synthetic surface basketball courts for primary and secondary schools and stipulates the requirements, sampling requirements, inspection rules and maintenance maintenance, and the corresponding test methods are described: This document applies to the design, construction and construction of outdoor cast-in-place surface and prefabricated surface basketball courts that are newly built, renovated and expanded in primary and secondary schools: acceptance:

3 Terms and definitions

The terms and definitions defined in GB 36246 and the following apply to this document: 3:1 synthetic surface A layer of polymer synthetic material paved on a base layer such as asphalt concrete or cement concrete:

Note: The synthetic surface layer mainly includes cast-in-place surface layer, prefabricated surface layer and artificial grass surface layer: [Source: GB 36246-2018, 3:1, with modifications] 3:2 in-situcastingsurface The surface layer of the pavement is poured on-site using polymer raw materials and other raw materials:

Note: The cast-in-place surface layer is divided into a permeable surface layer and a non-permeable surface layer: The non-permeable surface layer is further divided into a composite surface layer, a mixed surface layer and a fully plastic surface layer: [Source: GB 36246-2018, 3:2, with modifications] 3:3 permeable surface It has a pore structure: In addition to surface runoff, water also flows through the surface layer of the synthetic material surface layer:
