Synthetic materials sports field surfaces
1 Scope
This standard specifies the terms and definitions, product classification, requirements,
test methods, inspection rules, site foundation requirements, surface construction
conditions for the surfaces of synthetic material sports fields (hereinafter referred to as
the surface).
This standard is applicable to the surface of track and field, ball games and multi-
purpose sports fields, which are laid with synthetic materials outdoors.
This standard does not apply to occasions where climbing, sitting, lying are required.

3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Surface layers of athletic fields
A track-and-field surface layer, which is laid with synthetic material.
3.2
Surface layers of sports field for ball games
Court floors, which are made of synthetic materials, for basketball, volleyball,
badminton, tennis, football.
3.3
Synthetic surfaces intended for multi-sports facilities
Surface layers for recreational fitness activities, which are made of synthetic
materials.
3.4
Permeable surface
A synthetic material sports surface layer, which has a pore structure, AND on which
the water is in the form of both surface runoff and permeable surface flow.
3.5
Non-permeable surface
A synthetic material sports surface, which has a dense structure AND on which the
water on the surface is only in the form of surface runoff.
3.6
Prefabricated surface
A synthetic material sports surface layer, which is made by using adhesives or other
methods, to lay the surface layer material, on the foundation.
3.7
In-situ casting surface
A synthetic sports surface, which is formed by casting in site and paving the factory-
produced prepolymers and other raw materials.
4 Product categories
4.1 The surface layer is divided into the following three categories, according to its
scope of application:
- The surface layer of the athletic field;
- The surface layer of sports field for ball games;
- The synthetic surfaces intended for multi-sports facilities.
4.2 The surface layer is divided into the following two categories, according to its
structure type:
- Permeable surface layer;
- Non-permeable surface layer.
4.3 The surface layer is divided into the following two categories, according to its
paving method:
- In-situ casting surface layer;
- Prefabricated surface layer.
5 Requirements
5.1 Surface properties
5.1.1 Surface layer of athletic field
The performance of the surface layer of the athletic field, as well as the corresponding
test methods, shall comply with the provisions of Table 1.
6.2 Thickness
6.2.1 Sample thickness
6.2.1.1 Prefabricated surface layer: Use a thickness gauge, which has an index of 1/100
mm, a pressure of (22 ± 5) kPa, a foot diameter of 6 mm, to make measurement. The
measurement point is selected as follows: from the inside 20 mm from the end,
randomly select five points, along the width direction, to measure the thickness. The
arithmetic mean of the five points is taken as the result.
6.2.1.2 In-situ casting surface layer: The thickness of the in-situ casting surface layer
sample, with anti-skid structure, shall be measured by a vernier caliper, which has an
accuracy of not less than 0.1 mm. At least ten different positions shall be arbitrarily
selected, to measure the thickness, at the five convex points and five concave points
from the bottom to the surface, respectively. The result is the arithmetic mean of ten
measurement results. For the thickness of the in-situ casting surface layer sample, with
smooth surface, is measured by the method of 6.2.1.1.
6.2.2 Surface layer thickness of fields
The three-needle thickness detector (accuracy: ±1 mm) is used to make measurement.
The measured points and quantities shall meet the requirements of the surface layer of
the relevant sports field. The arithmetic mean of all the measurement points is taken as
the result.
6.3 Shock absorption
Make measurement, according to the method specified in Appendix B.
6.4 Vertical deformation
Make measurement, according to the method specified in Appendix C.
6.5 Anti-slip value, coefficient of friction
Make measurement, according to the method specified in Appendix D.
6.6 Tensile strength, elongation at break
Make measurement, according to the method specified in GB/T 10654; the tensile speed
is (100 ± 10) mm/min.
6.7 Tear strength
Make measurement, according to the method specified in GB/T 529. Adopt the right-
angle sample without cut; take the median of five specimens as the test result.
6.8 Ball bounce rate
(1 piece for testing, 2 pieces for sample preparation).
