Final answer:
The leakage test for a LRU-16P life raft typically lasts a minimum of 16 hours and a maximum of 24 hours to ensure any potential leaks are detectable.
Step-by-step explanation:
The LRU-16P life raft leakage test time frames are specified by the manufacturer's guidelines or the relevant authority requirements, with common practice being a minimum of 16 hours and a maximum of 24 hours for the leakage test. This period ensures that any potential leaks would be detectable, providing a reliable assessment of the life raft's condition.
During this test, the life raft is inflated and left to sit, with measurements taken initially and after the test duration to identify any loss of pressure that would indicate a leak. It's crucial for safety that these procedures are carried out meticulously and the raft maintained in pristine condition to ensure it is ready for emergency deployment.
