On March 15th, in the 3rd China National Standards Announcement of 2018, AQSIQ and the National Standards Committee approved the issuance of 240 national and 4 national standard amendments, including "the requirements for the use of sports fields and inspection methods: Part 7: Tennis Courts" GB/T 22517.7-2018. The new standard will be implemented on October 1, 2018.

Compared with the "Manual Requirements and Testing Methods for Sports Venues for Artificial Sports Venues Part 2: Tennis Courts" published in 2006 GB/T 20033.2-2005, the new standards improve stronger technical support for facility design, construction, installation and acceptance of tennis courts in China. The specific improvements are as follows:

First, increase the scope of application of the standard. The new standard addes the technical requirements for grassland and land tennis courts.

Second, internationalization. The standard is written with reference to the “ITF Approved Tennis Balls, Classified Surfaces & Recognized Courts - a Guide to Products and Test Methods”, and the American Society for Testing and Materials ASTM F 1953-99 "Standard Guide for Construction and Maintenance of Grass Tennis Courts". ”, the American Builders’ Committee and the Tennis Court’s “Tennis Courts – A Construction and Maintenance Manual” and EU-related technical standards, to ensure that high-level competition tennis courts built in China meet the requirements of international tennis courts.

Third, unified lighting requirements. The new standard no longer gives specific lighting indicators, stipulating that the artificial lighting fixture layout and lighting standard values shall comply with the relevant requirements of JGJ 153 "Design and Testing Methods for Stadium Lighting Design" to avoid the questions of design, construction and acceptance due to different reference standards.

Fourth, site size tolerances are given in the form of tables, and given the length range, so that the site design, construction and acceptance are more intuitive.

Fifth, increase the venue acoustic requirements. During the competition, when encountering an opponent with a relatively level, the player's attention is relatively concentrated and the physical exertion is heavy. All external factors will affect the player's level of competition. Therefore, the acoustic design of the stadium is very important. Therefore, the new standard proposes the acoustics of the tennis court building. Sound reinforcement and noise performance should comply with the relevant requirements of JGJ/T 131.

Sixth, remove the hard water permeability requirements. 1 The acceptance of hard water seepage will destroy the site, and few laying parties will be willing to accept the water seepage acceptance; 2 Acrylic sites are generally drained by slope, and the seepage performance is almost zero, so there is no need for acceptance.

Seventh, adjust the standard structure, the ball rebound rate, ground speed and sliding resistance detection methods listed in the normative appendix, easy to use.
