5.1 Determination of production capacity
Before the product is manufactured, water is used as the medium and the working conditions in 4.1 are followed. Under normal operation, the filling test is carried out. The production capacity should reach the nominal production capacity.
The product is used as the medium at the production site. Under the working conditions in 4.1, the liquid level accuracy is adjusted and the capacity meets the requirements. Under normal continuous operation, a filling test is carried out. The test time is not less than 20 minutes, and the production capacity is measured. The production capacity is calculated according to formula (1): Q-60 nF
Where: Q production capacity, bottles/h;
n-filling machine speed, r/min;
F-number of bottles filled per revolution, bottles.
5.2 Determination of filling qualified rate
QB/T2371—1998
Use the filling level difference to determine the filling qualified rate. Randomly select 200 bottles after filling and capping within 30 minutes, measure the liquid level height of each bottle, and calculate the filling and bottling qualified rate according to formula (2). 9
Where: q
Filling qualified rate determined by filling level difference, %, M--the number of bottles with filling level difference not greater than 12mm, bottles. 5.3 Determination of liquid loss rate
· (2)
Record the total number of bottles input into the filling and capping machine, the number of qualified bottles, and the number of recoverable bottles with unqualified liquid level (liquid level difference greater than 12mm) within 2 consecutive hours, and calculate the liquid loss rate according to formula (3).
In the formula: Sg #
Liquid loss rate, %;
PheNumber of qualified bottles, bottles;
S = [1 - Pm+(0.50~0.85)Pa)×100 Prg

Number of broken (damaged) bottles of filling and capping machine, bottles;
Pra—input the total number of bottles of filling and capping machine, bottles. 5.5 Determination of the damaged cap rate
（4）
Under normal filling conditions, count the number of damaged caps and the number of input caps (those damaged due to poor quality of the caps themselves are not counted). The number of caps counted continuously is 100 times the number of capping heads. After the test, the damaged cap rate is calculated according to formula (5). G
Where: G…damaged cap rate, %,
-damaged cap number, pcs,
-input cap number, pcs.
