6.16.1 Connect each air raft to a pressure gauge with a range of 40 kPa and a minimum range of 1 kPa, or use a pressure gauge with a range of 4 kPa and a minimum range of 0.25 kPa. The sphygmomanometer and the life raft air chamber are connected to compressed air respectively, inflated to the working pressure, wait for 30 minutes to stabilize, adjust the pressure to the working force, and record the time, temperature and pressure. After 2 hours, record the time, temperature and force again! Temperature compensation requirements: The temperature change during the test shall not exceed 3°C, and the pressure will be reduced or increased by 0.1 kPa for every 1°C increase in leakage. 6.16-2 Use compressed air to inflate the bottom of the life raft to the working positive force. After stabilizing the pressure, start calculating the time. After 15 minutes, measure the residual pressure and make a record. 6.17 Maneuverability and flooding tests shall be carried out in accordance with the requirements of 6.19 in HG2714. 6.18 Rope test
