   From which aspects does the inspection of the performance of EPDM plastic runway and school rubber permeable runway mainly come from you?

  
  The structure of breathable rubber runway in schools is not allowed to appear on the ground such as bubbles, cracks or delamination.
  
  Vertical deformation test for plastic runway: vertical deformation test using vertical deformation tester. The test is carried out on runway and runway (including thickening area). The temperature is 10 C -40 C at test. The vertical deformation of the ground should be between 0.6-1.88 mm.
  
  The standard of the ground flatness of the school EPDM plastic runway: any position on the ground of the track and field ground, no more than 6 millimeter local convex concave in any direction within 4 meters of the straight line jump distance, or more than 3 millimeters of the local convex and concave conditions within 1 meters of the straight line distance are not allowed, and the degree of convex and concave of each step must not exceed 1 millimeters.
  
  Color: evaluate the ground color of the artificial track and field, use the Ma Xiu Color Handbook, the color of the plastic should be consistent with one color of the manual. For carefully designed multi color plastic runways, each color should be consistent with the color of the handbook.
  
  The ground thickness standard of the breathable rubber runway in schools: the runway runway is at least 12 millimeters thick when completed. The runway thickness of any location shall not be less than 10 mm, and the total product of the runway with a thickness of 10-10.5 mm shall not exceed 5% of the total area of track and field. The plastic thickness of the track and field should not be calculated on the top of ground slag. The method of measuring thickness is that the surface area of the 60 stage until the friction is about 50% of the surface area of the core, and then the thickness meter with an accuracy of 0.01 millimeters, the measuring force between the plunger and 0.8-1.0 Newton with a 4 millimeter diameter measurement plane, and the measuring core. Body thickness, the test accuracy is close to 0.1 millimeters. Special thickening areas (pole vaulting, javelin, run-up area of the three level long jump and high jump zone) are not taken into account when calculating the above average. When the track and field facilities are used for large competitions, the thickness of any site should not be less than 10 millimeters when the thickness of the artificial site is measured by the above methods.
