3. Test procedures
3.1 Post operational packing vacuum test
CAUTION:
LIFERAFTS MUST ONLY BE TESTED USING THE
CORRECT MANOMETER.
After every service, each liferaft must be subject to this test. This ensures
that the liferaft’s hermetic seal has not been compromised during service.
A record of this test must be completed on a form similar to that in Appendix 3.
Such records must be kept by the service station for a minimum of 10 years
after the service date.
These records must be available on demand, for inspection by staff of
Revere Supply
. A similar record must be made when a service station
operationally
packs a new liferaft.
This test is to be completed after the upper half of the container has
been f
i
tted and the straps/crimps are installed. If desired the technician is
permitted to perform this test prior to the installation of the container upper
half. This will be an extra additional test. This additional test does not need
to be recorded. It does not negate the requirement to perform the off
i
cial
test.
3.2 Persons permitted to perform test
The Post operational packing vacuum test may only be completed (including
recording – see subsequent Section) by two technicians who are trained,
qualif
i
ed and competent in packing
the Revere Supply
liferafts in question.
