TESTING AND TROUBLESHOOTING
MANUAL No.

2. Preparation
A. Keep the records of all the inflation tests. A recommended format for the test
cards is shown in Table 1.
B. Keep the liferaft away from drafts and direct sunlight, as changes in temperature
can affect pressure.
C. Keep a solution of hard soap (not detergent), water, and a quantity of clean, dry,
lint free cloths in the area.
D. If a buoyancy tube needs to be tested separately because of a repair, carry out a
working pressure test.
E. Calculate the change in the buoyancy tube pressure, caused by any change in
temperature as follows (See Table 2).:
(1) Subtract .03psi (.86 in WG) from the manometer indication for each degree
Fahrenheit increase in temperature.
(2) Add .03psi (.86 in WG) to the manometer indication for each degree
Fahrenheit decrease in temperature.
F. Calculate the change in pressure caused by barometric pressure as follows:
(1) Subtract .0049psi (.136 in WG) from the manometer indication for each .01
in HG decrease in pressure.
(2) Add .0049psi (.136 in WG) to the manometer indication for each .01 in HG
increase in pressure.
3. Test Procedures
A. General
Test each compartment of the liferaft that inflates. Inflate the liferaft to the working
pressure. The separate compartments of the liferaft that are inflated by the gas infla-
tion system are:
1. The lower buoyancy tube and boarding ramp.
2. The upper buoyancy tube and the arch tube.
