Abstract
For determining the adequate perviousness of venting tube nipples ( ) on fuel tanks ( ) made of plastics material a test duct ( ) is connected to the nipple ( ) and air drawn into the test duct ( ) from the tank ( ). From measuring, the partial vacuum of e.g. approx. 5 mbar or the volume flow rate in the test duct ( ) it can be determined whether the nipple ( ) and its joint ( ) to the tank ( ) are sufficiently permeable. This test is very precise and silent and needs only little consumption of compressed air. Thereby the load on the sealing seat ( ) between test duct ( ) and nipple ( ) is only slight.
