6.1 External dimensions
From the cotton bales that have been processed and stored for 24 hours, take one bale out of every 20 bales (if less than 20 bales are counted as 20 bales) and measure the size of the cotton bales. Measuring method: Place the cotton bale to be measured on a flat surface, use two squares to lightly lean against the symmetrical surfaces of the cotton bale, and measure the corresponding cotton bale size: the measuring position is the two ends and the middle of each corresponding surface of the cotton bale, and the maximum value is taken. Then take the average value of the length, width and height as the actual measured value of the cotton bale size.
