From November 1, 2018, the "Synthetic Material Surface Sports Ground for Primary and Secondary Schools" (GB36246-2018) will be fully implemented;

In 2005, "Sports equipment and venues for elementary and middle schools Part 11: Synthetic surface sports venues" (GB/T19851.11-2005) issued by the state was abolished, and China's sports flooring industry will be measured by a new scale.

The new national standard requires all provincial education administrative departments to recognize the significance of the new national standard in improving the quality of synthetic material surface sports venues in primary and secondary schools, ensuring the health and safety of students, and improving the conditions for running school sports, and attach importance to synthetic material surface sports venues in primary and secondary schools. Construction, use and management of

This standard is promulgated. Compared with GB/T 19851.11-2005, GB36246-2018, what are the main technical changes except for editorial changes?

First of all, three additions:

1. Added 18 terms and definitions

Added synthetic material surface layer, cast-in-place surface layer, prefabricated surface layer, water-permeable surface layer, non-permeable surface layer, artificial grass for sports, impact absorption, vertical deformation, tensile strength, elongation at break, Terms and definitions of anti-skid value, aging resistance, flame retardancy, thickness, volatile organic compounds, total volatile organic compounds, non-solid raw materials, solid raw materials,

2. Added six items and indicator requirements

Added classification, paving requirements, sampling requirements; impact absorption, vertical deformation, antiskid value items and index requirements in physical and mechanical properties

3. Added two rules

Added inspection rules and judgment rules

Furthermore, two modifications (three requirements and seven methods)

1. Modify the thickness requirements; modify the tensile strength items and index requirements, modify the elongation at break and its index requirements

2. Modified the test methods of thickness, tensile strength, elongation at break, flame retardancy, test methods of impact absorption, vertical deformation and anti-skid value, physical and mechanical performance requirements and test methods of artificial grass surface layer, synthesis Material sports field ground layer aging resistance requirements and test methods, inorganic filler content requirements and test methods in synthetic material surface layers other than artificial grass surface layer, synthetic material surface layer non-slip rubber particles and artificial grass filling synthetic material particles. Quantity requirements and test methods, limit requirements and odor requirements and test methods of harmful substances in finished products and raw materials of synthetic material surface sports venues

GB 36246-2018 New National Standards for Plastic Tracks in Primary and Secondary Schools

It undoubtedly gave the school teachers, students and parents a "reassuring pill"

The industry has bid farewell to the "discoloration of the plastic runway" period

A new era of quality development has arrived!
