4.3.4 Leak tests
Perform the leak test with a suitable test unit (e.g. from the Testor or
Quaestor series).

4. Moisten the exhalation valve if necessary.
5. Generate a negative pressure of 10 mbar.
The full face mask is considered leak-tight if the change in pressure
after 1 minute does not exceed 1 mbar. Otherwise proceed with (2).
(2) Check with sealed exhalation valve
1. Remove the exhalation valve disc.
2. Insert the exhalation valve plug and fasten it with the spring carrier.
3. Generate a negative pressure of 10 mbar.
4. Remove the exhalation valve plug if the pressure difference is less
than 1 mbar after 1 minute, insert a new valve disc and repeat the
leak test. Otherwise, continue with (3).
