Two (2) of-these weighings shall be made within the first half of the shift and the other two weighings shall be made in the second half of the shift. Additional bag weights shall be taken, as required. 4.5.2.1.2 Procedure. Accurately weigh the ass
45、embled charge on a balance. Then, calculate the net weight of the propellant by difference using an average weight of the empty bags (as determined in 4.5.2.1.1). The calculation may also be performed by using the tare as marked on the individual bag instead of the average weight of the empty bags.
