Randomly select 100 sample bottles with qualified appearance quality, and use a torque meter with a dynamic accuracy of 1% to test the opening torque. It should comply with the provisions of 5.15.2. Count the number of unqualified products4.
6.9.3 Sealing air tightness test
Take the remaining sample bottles with qualified appearance quality, immerse them upright in a water towel of (50+2)℃ for 10min, and the bottle is qualified if there is no bubble overflowing; or apply a pressure of 200N to the side of the bottle and keep it for 10s. The sample bottle is qualified if there is no leakage at the mouth, and count the number of unqualified productsas9

The membrane filtration method is used for sterile water microbiological verification test. The inspection method is the same as 6.5.2.1. It should meet the requirements of 5.10. 6.5.6 Culture medium filling test
According to the production capacity of the equipment, use Lireler-Grain culture medium regardless of pH value for testing (pH value of low acid liquid food is 6.5~6.8. pH value of acidic liquid food is 4.3~～4.6). Fill the culture medium production station according to the normal production process. The filling is divided into 3 batches. The extraction time of each batch is not less than 24 hours. Each batch is filled with 10009 bottles. Test according to the provisions of GB/T4789.2 and GB/T4789.15. Observe the results. They should meet the requirements of 5.10. 6.6 Determination of peracetic acid or hydrogen peroxide residue in the bottle after sterilization After the aseptic line is running stably, randomly select 3K empty bottles that have been sterilized and disinfected and filled and directly capped (sealed) (K is the number of bottle heads, and 3 bottles are taken for each bottle head). Determine according to the determination method of hydrogen peroxide residue in the "Disinfection Technical Specifications". It should meet the requirements of 5.11. 6.7 Determination of peracetic acid or hydrogen peroxide concentration in the operating area After the aseptic line is operating normally, samples shall be taken at a distance of 1.2m from the aseptic rinsing, filling and capping (sealing) units and 1.6m above the unit. The concentration shall be measured according to the method specified in Appendix C of GB/T[8883-2002 and shall comply with the provisions of 5.12. 6.8 Filling accuracy test
Use a calibration scale with a maximum permissible error less than or equal to one third of the permissible deviation of the net content of the package being tested to weigh the net content of the contents in accordance with the provisions of Table 3. The difference between the measured net content of the contents and the marked net content shall comply with the provisions of 5.14: 8

The test is carried out after the sterile line is running normally. Under the condition of rated speed operation, sample bottles are taken in two batches: 100 bottles are taken from the continuous axis each time, a total of 210 bottles, and the time interval between the two times is not less than 10 minutes. The appearance quality of the sample bottles tested daily shall meet the requirements of 5.15.1, and the number of unqualified products a shall be counted.
