T/TSI A.1-2019 Synthetic material sports ground surface technical requirements

Scope

Scope: This standard specifies the terms and definitions, product classification, technical requirements, and test methods for the surface layer of synthetic sports fields; inspection rules; marking; and transportation and storage. Main technical content: 5.1 Paving requirements 5.1.1 The paving of the surface layer of synthetic sports fields should comprehensively evaluate the ventilation and dispersion conditions of the site and its surroundings, which should be conducive to the emission of volatile organic compounds and avoid pollution of the site and its surroundings by exhaust gases, wastewater, and solid waste during paving. 5.1.2 Before paving, a list of the raw materials required for use (including product names and quantities) should be provided. The raw materials used and the paved surface layer of the sports field under normal and expected use conditions should not pose a hazard to human health and the environment. 5.1.3 The surface of the synthetic sports field surface layer should be flat, clean, free from cracks, delamination, or damage, with consistent color and no obvious color differences. The adhesion between the surface layers should be firm and uniform. 5.2 Physical properties 5.2.1 The physical properties of the surface layer of synthetic sports fields should comply with the requirements of Table 1. Table 1 Requirements for the physical properties of synthetic sports field surfaces Test methods Thickness (mm) Average thickness of track and field surfaces ≥13 Average thickness of ball fields ≥8 Average thickness of other activity fields ≥10 Impact absorption % Water-permeable 35-50 Non-water-permeable 35-50 Vertical deformation (mm) Track and field surfaces 0.6-2.5 Ball fields, other activity fields 0.6-3.0 Anti-slip value BPN (20℃) ≥47 (wet test) Ball fields, other activity fields 80-110 Tensile strength (MPa) Water-permeable ≥0.4 Non-water-permeable ≥0.5 Elongation at break (%) ≥40 Combustion performance Class I Aging resistance (after 168 ho
