Where the apparatus
is used and stored at
a known temperature
the
pressure
dewpoint shall be at
least 5°C below likely
lowest temperature.
Where the conditions
of usage and storage
of any compressed air
supply is not known
the
pressure
dewpoint shall not
exceed -11°C.
Dewpoint ≤50°F (67
PPM v/v), for SCBA
use in extreme cold a
dew point not to

for cylinders initially
filled to pressure of at least

Note – Also ensure that the test point volume and pressure is sufficient for the RPD being used. For
AS-NZS 1715 the minimum requirement is 170 l/min continuous flow for each person, measured at
the respirator.
