5.3 The table surface material, table surface quality, table surface stability, table surface folding direction should be measured in accordance with the requirements of 4.1, 4.4, 4.6 and 4.9: Elasticity and elasticity uniformity
OH/T2700-2005
Use a high-quality table tennis ruler to measure the height of the ball with a distance of 300mm. Drop it on the ground with a hollow, measure the rebound height of the ball, and perform three elasticity tests on the measuring point. The average value is the elasticity of the table. After the designated pilot test, the difference between the high average signal and the low recorded value is the elastic uniformity, which can be determined by slow image or special controlled neutron elastic measurement method (system error 2mm). Starting from the test, 16 general points and special points (the reverse contact points of the tripod body and the table top) are preset on the convex surface of the spherical ball according to a certain size (see Figure 9), and the test is carried out at each point to determine the qualified product. The concave corner of the spherical table surface can be selected for the middle point method. 6.6 Glossiness of table surface
Measured by G0\radio photoelectric photometer
5.6 Y value of ball surface wax abrasion

Under D65 as source, measured by colorimeter (colorimeter): 5.7 The friction coefficient CF of table surface and ping-pong ball
Use a ruler: the distance between the two balls is 20mm>, with a total mass of about 0.5mm. Put a triangular skateboard on the table, and the center of the ball gradually moves along the groove. When the triangular skateboard starts to move, the tangent value between the table surface and the water half is called uF (see Figure 10)

When the table is at a certain angle with the horizontal plane, the maximum height of the table is above the ground:
The angle between the table surface and the horizontal plane.
5.8 Determination of table displacement
A fixed baffle is placed in front of the table feet of the user's billiard net in the direction of force application, which is a fixed control in the direction of force application, and the center of the ball falls. When measuring the ball's performance, apply a 3 N pull (Figure 1). When measuring the stability of the table, apply a 200 N pull (Figure 12).
