Testing pressure reducer of the SCBA

INFO
Self-contained (open-circuit) breathing apparatus in which the
lung demand valve is permanently connected to the pressure
reducer cannot be tested as described below. Contact the
manufacturer for information.
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. Connect pressure reducer to the inlet for the compressed
air supply.
WARNING
The following work is on the high-pressure system. If parts
become disconnected from the system, there is risk of injury.
► Make sure that all connections are secure before opening
the cylinder valve.
2. Open cylinder valve.
Testing static medium pressure and medium-
pressure rise
1. Press right control lever briefly twice.
2. Read the pressure at the medium-pressure gauge and
compare with the target value:
The pressure must be between 6 bar and 9 bar.
3. Start test time of 1 minute on the timer.
4. Read the medium pressure at the end of the test time.
The pressure must not rise by more than 0.7 bar or fall
more than 0.2 bar.
Performing high-pressure leak test
1. Close cylinder valve.
2. When the cylinder valve is fully closed, read the pressure
at the SCBA immediately.
3. Start test time of 1 minute on the timer.
4. Read off the pressure at the end of the test time.
The pressure must not fall more than 10 bar.
