Allow a small amount of unclear printing, but no missing words. The ball surface is clean, with defects and pollution less than or equal to 7%, and no obvious scratches.
5.1.2 Method: Measure each ball three times, each measurement is 90° from the previous measurement, and the arithmetic mean of the circumference values ​​obtained by the three measurements is taken as the circumference value of the ball.
5. 2 Measurement of circumference difference
5.2.1 Tool: Use a metal flat soft ruler with an indication of 1mm. 5.2.2 Method: Measure each ball three times, each measurement is 90° from the previous measurement, and the maximum difference of the circumference values ​​obtained by the three measurements is taken as the circumference difference of the ball.
5.3 Measurement of mass
5.3.1 Tool: Use a weighing instrument with an indication of 1g. 5.3.2 Method: Place the ball on an accurately adjusted scale for weighing. 329

5.4.1 Tool: Use a metal flat ruler with an indication of 1mm. 5.4.2 Method: Inflate the ball to meet the requirements of Table 1, let it stand at room temperature for 24 hours, and then measure the percentage of its circumference drop. 5.5 Measurement of rebound height.
5.5.1 Tool: Rebound height meter.
5.5.2 Method: Inflate the ball to meet the requirements of Table 1, clamp the ball mouth upward on the fixture, and the bottom of the ball is 1800mm away from the bottom plate of the rebound meter. After free fall, read its rebound height value (the value reached on the top of the ball). Each ball is tested 10 times, and the arithmetic average is taken as the rebound height value. 5.6 Appearance inspection
Mainly by visual inspection, trademarks, patterns, colors should meet the requirements of product drawings. Steel rulers can be used when necessary. The indoor light should be sufficient and the viewing distance should be 300mm. bzxZ.net
