2.Test principle:
The tester walks on a sloping slope paved with specimens, gradually increasing the Angle of the slope until the limit Angle of safe walking on the slope is reached. This is used as the critical Angle to reflect the non-slip degree of the specimen surface.

2 Test equipment and materials
2.1 Test equipment
The test device is mainly composed of a platform with a width of about 600 mm and a length of about 2 000 mm, on which specimens can be placed and safety devices such as guardrail and safety belt are provided on both sides. The platform is controlled by the test personnel and can be continuously rotated from a horizontal position in the range of 0° to 45° with a precision of 0.2°. Because the tester walks on the I: surface, the influence on the Angle should not exceed 0.5\ platform. The platform is also equipped with a water spray device that can roughly evenly spray the detergent solution on the specimen table at a flow sense of (6.0± L0)L/min during the test. The schematic diagram of the test device is shown in Figure C.1.

C2.2 Test materials
C2.2.1 Three barefoot test calibration boards, see Table C.1 below
C.3 Specimen
The area of the specimen is approximately 100 cmX50 cm.
C.4 Calibration
Prior to the test, both testers shall survey the ground in accordance with step C.5 and calculate the average critical Angle on the three calibration plates for the barefoot test and the three calibration plates for the shoe-on test, if the difference between the average and the standard value of the corresponding plate is not greater than the limit deviation value in Table C.1 or Table C.2. Then the test can continue. Otherwise, find the reason or even change the tester.
| Calibration plate | Standard value of critical Angle | Limit deviation value |
| St-A | 11.5 ° | 2.1 ° |
| St-B | 18.5 ° | 2.1 ° |
| St-C | 23.9 ° | 2.1 ° |
| Calibration plate | Standard value of critical Angle | Limit deviation value |
| St- | 8.7 ° | 3.0 ° |
| St- | 17.3 ° | 3.0 ° |
| St- | 27.3 ° | 3.0 ° |
