b. The hydraulic test and tightness test of each system pipeline are qualified 1c. The safety valve calibration is qualified.
16.2 Test content and sequence
16.2.1 Water fire extinguishing system test
16.2.1.1 The fire pump shall be tested for water for no less than 1:30min. Check whether there is abnormal vibration and heating. During the test, the number of water guns to be used should be estimated based on the pressure head and displacement of the fire pump selected in the design, the caliber of the water gun used and the water output (see Table 2). During the test, the number of water guns spraying water at the same time shall not be less than 2 under any circumstances. 16.2.1.2 Two fire pumps are allowed to supply water to the fire main at the same time, and the water output of the two pumps is discharged from any adjacent fire hydrant through the selected water guns according to the output specified in the regulations. At this time, the pressure at other fire hydrants is measured. 16.2.1.3 For cargo ships with a gross tonnage of less than 1,000, the above test can be replaced by a water spray test with two water guns, and the range of the water jets of the two water guns is measured.
16-2.1.4 When the emergency fire pump outputs the water output specified in the regulations, measure the pressure at other fire hydrants. 16.2.1.5 When the fire-fighting system, such as the deck water system of the oil tanker, the foam fire-fighting system, the automatic sprinkler system and other water-using fire-fighting systems on board are used, the above test should be carried out when all systems are in operation at the same time. 16.2.1.6 Carry out the effectiveness test of portable fire pumps (if provided). 16.2.1.7 If the driving power of the emergency fire pump is a diesel engine, the diesel engine driving power source shall be tested for starting.

16.2.2 Automatic water spray system test
Water gun caliber
16.2.2.1 Check the reliability of the automatic start-up of the water supply pump. 10
Water gun caliber
W.GB/T 3471-.. 1995
16.2.2.2 Action test of reverse fire alarm and automatic sprinkler system. 16.2.2.3 Use the main power supply and emergency power supply to carry out effectiveness test respectively, and check the flexibility and reliability of the operation of the conversion switch of these two power supplies. When returning, check the effectiveness of the sound and light signals indicating the automatic sprinkler system. 16.2.3 Pressure water mist system test
16-2.3-1 Check the water mist of each nozzle and whether its distribution in the space is uniform and effective. 16.2.3.2 Select any nozzle for pressure test and check its water output rate. 16.2.3.3 Check the regularity of the water supply pump. 16.2.3.4 Check whether the measures to prevent the nozzle from being damaged by impurities in the water or rust of pipes, nozzles, valves and water pumps are effective. 16.2.4 Carbon dioxide fire extinguishing system test
