NOTICE!
Our workers perform a water bath test on all gassing lids.
The part to be tested is sealed, a pressure of 5.5 bar is
applied and it is immersed in a water bath. If there is a leak,
bubbles will develop. The air bubbles that develop within a
specific interval are evaluated by the worker/tester.
Only gassing lids with a leak rate of <10
-4 [mbar l/s] are
approved.
