The full length of the racket is measured with a steel ruler, and the deviation value of the symmetrical point of the racket is 0. The vernier caliper is used to measure. 3. 2 Weight
Measured by measuring (sensing 0,2).
3.3 Balance point
Q8/T36531999

Put the free throw racket flat on a fulcrum of the measuring tool to keep the racket body balanced, and then measure the length from the fulcrum to the end of the racket body (see Figure 3) ten points

3.4 ​​Rebound force test
Put the racket From the bottom of the racket to the 100mm~120m part, the upper end is fixed with a ball of 26mm diameter, 40mg weight, and 250mm hip length. The ball falls naturally from the water level and is impacted ten times. When it hits the racket net five times, calculate the average value of the rebound angle (the angle with the vertical). However, in order to make the front end contact the racket net in the vertical position, it must make an angle with the racket net surface:

3.5 Degree of deflection
3. 5. 1 Degree of deflection
Use a piece of board to draw a straight line in the middle, align the center of the handle of the racket and the center of the two holes at the top of the racket with the straight line, and then observe that the deviation between the two holes at the top of the racket handle and the straight line does not exceed 2.2. The indicators specified in the table (5) are as follows (see Figure 5). 3.5.2 Place the racket flat on the ground, use a tape measure to measure the width between the top of the grip and the half of the back, and the positive and negative measurements shall not exceed 2.2 of the specified indicators in 1 (G) (see Figure 6): \ Plate
3.8 Electroplating Etching Test

Place the racket rod on two fulcrums with a middle distance of 240mm, apply static force at the center of the racket rod, and its lower dimensions meet the requirements of Table 2 in 2.7, then remove the pressure, measure the difference between its deformation and the original position (horizontal line), and meet the requirements in 2.3 Record 2 (see Figure 7).
3.B Racket pull test
Institute pressure
QB/T 3653-1999
Take a blade-length guard, one end is tightened on the quality frame, and the other end is pulled by the force control device. The length index is set as specified in Table 3, and it needs to break. 3.9 Appearance 4 Inspection rules 4.1 Delivery inspection Each batch of products shall be inspected by the quality inspection department according to this standard before delivery. Only those that meet the standard shall be shipped out of the factory. 4.2 Acceptance test 2.2.
