Testing chemical protective suit (type 1b)

Visual inspection
Inspect all components. Check in particular for possible

damage (e.g. deformation, adhesion, contamination or
cracks). Replace faulty or damaged parts immediately.
Preparation of test
1. Seal the connections for protective suits with ventilation unit.
2. For protective suits with face cuffs:
a. Blow up the test fan moderately and close with a
hose clip.
b. Moisten the test fan with water and insert through the
open fastener system into the hood on the protective
suit.
c. Continue to blow the test fan until the face cuff is in
position all-round.
d. Close the test fan with a hose clip.
3. For protective suits with integrated full face mask:
a. Remove the protective cap from the connector.
b. Seal exhalation valve and inhalation valve with the test
accessories.
4. Close the fastener system.
5. Spread out the chemical protective suit back-down on a
clean and even surface.
6. Unfasten the protective cap from the suit valve and remove
the valve disc.
7. Fit the double test cap onto the suit valve.
8. Connec t the grey hose to a connector of the double test
cap and connect to the test unit with the mouth adapter.
9. Connect the black hose to the second connector of the
double test cap.
10. Make sure that both valves are closed at the black hose.
11. Connec t the black hose to the medium-pressure outlet of
the test unit.
12. Connect test unit to medium pressure.
Check the seal on the chemical protective suit
1. Open the exhaust valve on the black hose and fill the
chemical protective suit until the test unit shows 17.5 mbar.
Close exhaust valve.
2. Set a settling time of 10 minutes and start the stopwatch.
During this time, keep the pressure at approx. 17 mbar to
enable a pressure and temperature compensation.
If necessary, regulate the air with the applicable control
lever (+ or -).
3. Pull right control lever to reduce the pressure to 16.5 mbar.
4. Start test time of 6 minutes on the timer.
5. Read off the pressure at the end of the test time.
