Tests for Airbag:
1. Air tightness test
Fill the air into the pneumatic lifting bags to a certain internal test pressure without any load. After one hour, measure the internal pressure again. By comparing with two times’ data, the pressure loss should be less than 5%.
2. Performance test
Without any load, fill the air into the airbag balloon by the airbag standard data form or by clients’ requirement.
We will do the strictly inspection before the delivery for the outer appearance and the air loose test. If it is unqualified, can not release definitely.
3. Blasting test
This test should give the minimum burst pressure value of the airbag, as listed in the airbag performance table burst pressure. In order to be safe, since the airbag belongs to the pressure vessel, it is necessary to use a water flushing while filling the airbag until the airbag bursts. The water pressure during airbag blasting should be larger than or equal to the values listed in the standard performance table.
4. Compression-recovery Test
In order to verify the recoverability of the airbag, the airbag should be repeatedly and rapidly compressed and released in a short time. Due to the limitation of the airbag length and the limitation of the compression recovery equipment, the compression recovery test can be reduced by the same number of layers. The airbag is inflated to make the internal pressure reach the pressure of the airbag performance data. And the airbag is vertically compressed until the compression deformation reaches 75%. Keep this state for 1 minute. The pressure is then released and the balloon diameter should be restored to more than 97% of its original diameter within 5 minutes.
