Leak tests

The leak test should be performed with an appropriate test device (e.g.
the Testor or Quaestor series) and the adapter and exhalation valve
test plug.
(1) Checking leak tightness
1. Moisten the face seal and exhalation valve with water.
2. Mount the full face mask to the test head.
3. Make sure that the face seal fits tightly onto all parts of the test
head. Inflate the test head, if necessary.
4. Seal the equipment connector with the adapter and produce a
negative pressure of 10 mbar.
The facepiece is considered leak-tight if the pressure drop is less than
1 mbar/min. If the full face mask leaks, continue with (2).
