1 Scope

GB/T 22517.1-2024 sets the requirements and test methods for the timber sports floor of a multipurpose gymnasium. A sports floor is a mechanical system rather than a surface: what protects a player's joints is the shock absorption of the sprung construction beneath the boards, what determines ball sports is the vertical deformation and the ball rebound, and what causes injuries when it is wrong is the friction, too little and players slip, too much and they catch. The standard sets the categories of floor, then the requirements: the basic requirements, the appearance of the finished court, the physical and chemical properties of the timber and the finish, and the sports performance of the assembled system, shock absorption, vertical deformation, ball rebound, sliding friction, rolling load, area deflection and surface planarity, together with the formaldehyde and volatile emissions and the fire behaviour. It then gives the test methods for each of those, the inspection rules and the acceptance of a completed installation. It takes effect on 1 February 2025.

This document specifies the classification and requirements for sports wooden flooring, describes the corresponding inspection methods, and establishes the rules for determining eligibility. This document applies to the construction and inspection of sports wooden flooring used in indoor sports events. Stages, dance halls, amusement halls, etc. Wooden flooring venues can be used for reference. This document is not applicable to wooden sports floors for indoor sports with special requirements, such as weightlifting, throwing, etc.
