Introduction

The surface performance test method is an important technical support to verify whether the sports surface meets the requirements for use, ensure sports safety, and ensure the quality of the venue. support. TY/T 2003 "Sports Surface Performance Test Methods" series of standards aim to consolidate the basic standard system of sports facilities and equipment, provide scientific, An efficient and advanced method for testing motion surfaces. In order to avoid the length of the standard and simplify the process of using the standard query, the standard will move the surface layer performance. The test methods for each project are respectively established and are to be composed of the following parts. --- Part 1.Specifications. The purpose is to provide a detection method for the flatness, slope, size, angle, etc. of the moving surface layer. --- Part 2.Thickness. The purpose is to provide a detection method for the thickness and absolute thickness of the moving surface layer. --- Part 3.Anti-slip value. The purpose is to provide a detection method for the anti-slip value of the moving surface. --- Part 4.Shock absorption. The purpose is to provide a detection method for the impact absorption of the sports surface layer. --- Part 5.Vertical deformation. The purpose is to provide a detection method for the vertical deformation and standard vertical deformation of the moving surface layer. --- Part 6.Ball rolling performance.
