6.2.1 For products that have passed type inspection, the consistency of production shall be determined by taking samples taken from non-standard products: 6.2.2 The sample taken from the machine shall meet the requirements specified in 1.1, and the shape and size shall meet the requirements of 6.1.2a.
6.2.3 The number of samples taken at random shall be 4.3, 1.14, 3, 2, 1, and the CIL value and size value shall be at least 8% of the specified values; otherwise, take 5 samples, and the average of the measured (I value and β value shall be at least equal to the specified values, and any measured value shall not be lower than 50% of the specified value.

Use the "sand pool" method to determine the roughness of the road surface. The purpose of this method is to carry out a 5.10 resistance to stability test, and install the ordinary brand on a road surface with a certain geometric roughness. C.2 Principle of the method
C.21 A certain volume V* is dropped on the test road surface to form a circle. The ratio of the volume to the surface area S is the depth of the test surface HS (unit: mra)
HS-V/S
2.2 The test city uses 150~0.215mm light sand, the volume is 2>1nL+0.15ml. The formula month-vertical behavior 5r is a 5-5 plate, the sand is spread on the test road surface, and one side of the plate is covered with a rubber test plate with a thickness of 1.5~2.6mm. If the vertical grid is the same as the vertical grid, the sand can be pulled down. The depth of the flat groove is: HS-1.2.10'mm
c.3 Test work
center, 3, 1 embedded test The road surface must be dry and soft to remove dirt or sand: C.3.2 Place the sand already in a suitable container on the cut-off or lower surface, then use the disk to move it repeatedly, carefully spread the sand on the center of the test road to form a small area of the test road, and use the sand to fill the other areas and holes on the road surface. 3.2 When measuring the diameter of the circle of grass and sand, it should be done on the line through the center of the circle. The maximum and minimum line should not exceed 5mr. Then the formula F is used to calculate the HS of the sand. C.3.4 Carry out the test twice or make the error as evenly distributed as possible on the test. The average position of B times reaches S=D.5mm0.C5m% system quality requirements, which is the effective benchmark road with billboards. Otherwise, the test road should be updated and selected.C5m% system material degree requirements, that is, the reference road with effective warning signs, otherwise the test road rain should be updated.C5m% system material degree requirements, that is, the reference road with effective warning signs, otherwise the test road rain should be updated.
