Conducting A Pressure Test - DuPont Tychem TK Manuel D'utilisation

Conducting a pressure test

1. Lay the suit out as flat as possible, away from any source of
heat and/or currents of air. Seal the exhalation valves with the
rubber bungs provided.Visually inspect the suit and remove
any creases and folds as far as is practicable. Leave the suit
at ambient temperature (20 °C ± 5 °C) for minimum of 1 hour.
2. Connect the black hose from the port marked 'SUIT' on the
test rig to the airline coupling on the suit. Make certain that
the rig selector valve is turned to
'SAFE'. Connect a suitable com-
pressed air source providing air at
approx. 15 psi (1.03 bar) to the port
marked 'AIRLINE' on the test rig.
3. Turn the rig selector valve to 'INFLATE'.
Inflate the suit carefully to a pressure
of 1750 ± 50 Pa. Ensure that any
creased areas are unfolded and
that the suit takes up its full shape
(see Figure 16).
4. Check the inflation level by turning the
valve through 'SAFE' to 'TEST'. When
the pressure begins to approach the
marks inflate a little at a time until the
bottom of the red area is reached.
