1. General
1.1 The items described in CHAPTER 10 are necessary to test the liferaft.
When not in use, keep the test equipment and all special tools in conditions
that protect them from damage:
1.2 The liferaft shall be submitted to pressure and other physical tests according
to its age as defined in TABLE 502 and as described in this Chapter section
4.2.
2. Preparation
2.1 Keep the records of all the inflation tests. A recommended format for the test
cards is shown in TABLE 501.
2.2 Keep the liferaft away from draughts and direct sunlight, as change in
temperature affects pressure.
2.3 Keep a solution of hard soap (not detergent), water, and a quantity of clean,
dry, lint free cloths in the area.
2.4 If a buoyancy tube needs to be tested separately because of a repair, carry
out a working pressure test.
2.5 Calculate the change in the buoyancy tube pressure, caused by any change
in temperature as follows:
2.5.1 Subtract 38 mm WG from the manometer indication for each degree
Celsius increase in temperature.
2.5.2 Add 38 mm WG to the manometer indication for each degree Celsius
decrease in temperature.
NOTE: The test result is not accepted if the temperature
changes by more than 3.5° C.
2.6 Calculate the change in pressure caused by barometric pressure as follows:
2.6.1 Subtract 10.2 mm WG from the manometer indication for each
millibardecrease in pressure.
2.6.2 Add 10.2 mm WG to the manometer indication for each millibar
increase in pressure.
