Each sample is 15mm wide, 50mm long in the direction perpendicular to the seal length, and 100mm long after being flattened at 180°. Place the two ends of the sample with the seal in the middle in the fixture of the electronic universal testing machine. The distance between the fixtures is 50mm, the test speed is 300mm/min±20mm/min, read the maximum load when the sample breaks, and take the lowest value of the sample load for each bag as the sealing strength of the bag.

Colony test on clean room space: First, place the plate filled with culture medium (sterilized) into the clean area (room) (whose cleanliness has reached the a)
100 grade standard). After cleaning and sterilization according to SOP, open the plate at the set key point for no more than 10 minutes, then operate the sterilizing machine normally, maintain air flow in the clean area (room), and conduct dynamic testing. , after 30 minutes, cover with blood, and then put it in the incubator for cultivation. Test according to the provisions of GB/T4789.2, observe the results, and it should meet the requirements of 5.8; b) Clean room equipment surface colony test: smear test on the surface of clean room equipment, use sterile cotton swab to smear and sample the designated position (generally arranged on the surface of equipment that is not easy to clean, and the position with extremely high sterility requirements, such as near the filling head), test according to the provisions of GB/T4789.2, observe the results, and it should meet the requirements of 5.8. 6.5.2 Microbiological verification test of packaging materials Take 20 empty bags after sterilization and sealing, cut the test bags along the longitudinal seam in the sterile laboratory, cut them into the largest rectangular shape, and measure the area, accurate to 0.1cm2. Take 100mL of sterile water, wipe the surface to be tested repeatedly with sterile cotton soaked in sterile water, and test the total number of bacteria according to the provisions of GB/T4789.2.

The residual amount of hydrogen peroxide shall be determined according to the method of "Technical Specifications for Disinfection" (2002 Edition), and the determination results shall comply with the provisions of 5.10. 6.7 Temperature control test
Adjust the temperature regulator to the heat sealing temperature value, and use a thermometer (the accuracy of the thermometer is ±1.5℃ and the resolution is 0.1℃) to measure three points on the effective length of the heat sealing part, one of which is the midpoint, and the other two are respectively taken at 15mm from both ends of the effective heat sealing length. The temperature difference of the three points measured shall comply with the provisions of 5.11.
