2 1 century, with the progress of our society and the improvement of people's living standards, China has paid more and more attention to physical education. Synthetic material ground sports ground has become one of the basic hardware of stadiums, schools and colleges, and has been laid in a large number of primary and secondary school sports fields and indoors. Every year, the sports ground on the surface of various synthetic materials exceeds 2.5 million square meters, which is the largest sports ground synthetic material surface market in the world. In order to standardize the quality of synthetic material ground sports ground in primary and secondary schools, the Ministry of Education took the lead in formulating the national standard GBT19851.1-2005 "Sports Equipment and Ground for Primary and Secondary Schools Part 1 1".

Since 20 15, plastic track has become the focus of parents and media. Students in many places have nosebleeds, coughs, dizziness, rashes and other symptoms, and even some children have abnormal coagulation function. Parents suspect that it is related to the plastic runway and have asked for the removal of the plastic runway. The "poison track incident" once triggered a heated discussion, and all sectors of society reacted strongly. In order to further standardize the market, ensure product quality and protect students' health, the Ministry of Education decided to organize the revision of GBT19851.1-2005 on 20 165438, hoping to standardize the development order of the synthetic material ground sports ground construction industry by perfecting the standard content, clearly stipulating the requirements for the limit of hazardous substances, and promoting the development of the industry.
