MAIN TEST  PROJECT

Airtight performance:  
measured by vacuum seal performance tester.
Resistance to internal pressure:  
after the sample bottle is filled with water, it is pressurized to a specified value of 30S under the protective device to observe whether the sample bottle is broken or leaked.
Drop test:  
within the sample bottle injection of nominal capacity of water proof, 24 h - 18 ℃ environment pretreatment, then put the bottle according to physical properties specified in table 2 the height of the fall, to the weak parts of the crashed on the cement ground, each bottle dropped five times in a row, observe whether sample bottle is broken.
Leakage detection:  
at least 5 sample bottles shall be loaded with water of nominal capacity, capped, sealed by sealing machine, and inverted at room temperature for 48h to observe whether there is any leakage of sample bottles.
