3.3.1 Negative pressure test
 Seal both respiratory filters with your hands or an aid (e.g. a piece
of cardboard) and breathe in until a negative pressure is created
(refer to figure H). Hold your breath for a moment.
The negative pressure should be maintained. If not, adjust the
harness.
3.3.2 Positive pressure test
 Seal the exhalation valve of the half mask and breathe out
forcefully (refer to figure J).
The half mask must NOT lift off your face. If the exhaled air
dissipates between face and mask body, adjust the harness.
