T/YDRTKX 001-2025 The quality requirements and testing methods for the elastic particles used in the synthetic surface of sports venues
Basic Information
Scope
Scope: This document specifies the quality requirements for the use of elastic particles in synthetic material surfaces for various sports venues, as well as the test methods, sampling requirements, and inspection rules. This document applies to all types of outdoor sports venues and walking paths with synthetic material surfaces, including but not limited to rubber particles used in the base layer, surface layer, and infill layer of synthetic material surfaces. Rubber particles used in indoor venues can refer to this document for implementation. Main technical content: (1) For synthetic material surfaces, the total polymer content of anti-slip rubber particles and artificial turf infill particles should be ≥ 20%. For other surfaces, the total polymer content of particles used should be ≥ 15%. After comparing the test results of 30 suppliers' rubber particles with 5%, 10%, and 15% rubber content, the samples with confirmed rubber content were selected. Then, under unified proportions, using high-quality adhesives and the same construction methods and environments, we produced 13-mm-thick breathable and mixed experimental samples. According to the test methods in GB 36246, except for the 5% rubber content samples that failed to meet the requirements for impact absorption and vertical deformation, the samples with 10% and 15% rubber content all met the requirements of GB 36246. Therefore, we verified that the total polymer content of particles used in the surface layer should be ≥ 10%. Since the national recommended standard GB/T 43564-2023 [Secondary School Synthetic Material Surface Athletic Fields] stipulates that the total polymer content of infill particles in the base layer of the surface layer should be ≥ 15%, which will be implemented from July 1, 2024, this standard adjusts this indicator to ≥ 15%, with better performance. (2) For plastic particles, the limit values and detection methods for six phthalate plasticizers, 18 polycyclic aromatic hydrocarbons,
