5. Test of S mask and breathing valve
NOTE: A tested and approved regulator is required for all mask and breathing valve tests.
5.1 Leak test of S mask with breathing valve
1. Inflate the Test head (4) slightly by pressing the Vacuum pump button (10) and the
Test head inflation button (11).
2. Put mask with breathing valve on to the Test head (4) and firmly tighten the lower
straps and head strap (top). Do not tighten the upper straps.
3. Inflate the test head by pressing the Vacuum pump button (10) and the Test head
inflation button (11) until the sealing edge of the mask seals tightly around the test
head.
4. Connect the breathing valve (on mask) to the Test connection (3) with Adapter hose
ST-P49 (G).
5. Manually activate (ON) the positive pressure lever on the breathing valve (First
Breath version), or close the hatch on the mask (Hatch version).
6. Create a negative pressure of -10 mbar on the Low pressure gauge (2) by pressing
the Vacuum pump button (10) and the Negative pressure button (14) at the same
time.
7. Start the stop watch and after 15 seconds record the value on the Low pressure
gauge (2) and compare with the required test value.

Troubleshooting
If the test values indicate that the mask/breathing valve assembly has a leak then the mask
and breathing valve should be tested separately as shown in the next procedures.
5.2 Leak test of S mask without breathing valve
1. Connect the mask (without breathing valve) to the Test connection (3) with Test
adapter BV P/Divator (I) and Adapter for breathing resistance (L).
2. Create a negative pressure of -10 mbar on the Low pressure gauge (2) by pressing
the Vacuum pump button (10) and the Negative pressure button (14) at the same
time.
3. Start the stop watch and after 1 minute record the value on the Low pressure gauge
(2) and compare with the required test value.
4. Disconnect Test adapter BV P/Divator (I) with Adapter for breathing resistance (L)
and the mask from the Test connection (3).
