United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in t

17、he Decision on Principles for theDevelopment of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.15.7 Each searchlight shall be wired with a 6-ft (2-m) lengthof rubber jacketed hard service flexible cord, unless ot

18、herwisespecified in 8.3. The conductor size shall be no less than 16AWG. The cable entry into the searchlight shall be sealed witha watertight bushing and packing gland. A suitable clampingdevice shall be installed in the area where the cables enter thegland to prevent any force being exerted on the

19、 gland orconnections. The free end of this cord shall be dead-endedunless otherwise specified in 8.3.5.8 Each searchlight shall be provided with a handle orhandgrip to allow for ease of maneuvering the light intovarious positions.6. Workmanship, Finish, and Appearance6.1 Searchlights shall be of stu

20、rdy construction, and freefrom mechanical, electrical, or other imperfections or defectswhich materially affect appearance or which may affect quality,reliability, or serviceability.6.2 The finished searchlight shall not contain rough edges,burrs, or other disfigurations and shall be clean, free fro

21、m rust,tool marks, and other injurious defects.7. Test Methods7.1 WatertightnessThe searchlight shall be submerged in a60F (16C) saltwater solution (1.04 sp gr) to a depth of 3 ft(0.9 m) for 2 h. The light will then be subjected to the tests of7.2.1 and be in perfect working order.7.2 Environmental:

22、7.2.1 Operational TestThe searchlight shall be operatedcontinuously for3hatrated voltage in an ambient temperatureof 77F (25C) and be operational after being subjected to thewatertightness test of 7.1. The searchlight shall then beoperated intermittently. The intermittent time periods shall be15 min

23、 “ON” and 5 min “OFF” for a total 6-h period. Thesetests shall be repeated three times.7.2.2 Impact Test ConditionsThe searchlight shall beplaced in a cold chamber at 40 6 5F (40 6 3C) for 2 h.With the searchlight stabilized at this temperature, it shall beimmediately subjected to the low- and high-

24、impact testsspecified in 7.2.2.1 and 7.2.2.2. The point of impact shall beapplied to the outside of the case at a point midway betweenthe ends of the case at 4 points 90 apart and the back plate.7.2.2.1 Low ImpactThe searchlight shall be subjected to a12 in.lbf (1.3 J) impact using a 1-lb (0.5-kg) s

25、teel ball at eachof the points of impact specified in 7.2.2. The searchlight shallthen be subjected to the watertightness test (see 7.1). Thereshall be no evidence of breakage from impact and no evidenceof moisture shall be found in the case.7.2.2.2 High ImpactThe searchlight, after passing thelow-i

26、mpact test, shall be again placed in the cold chamber at40 6 5F (40 6 3C) for 2 h and then immediatelysubjected to a 20 in.lbf (2.3 J) impact using a 1-lb (0.5-kg)steel ball at each of the points of impact specified in 7.2.2.There shall be no evidence of damage to the case or the lens.7.3 Test for L

27、ight ProjectionThe beam spread of thesearchlight shall be shown to meet the calculations contained inthe IES Lighting Handbook.4This test shall be conducted atrated voltage.7.4 Switch EnduranceThe contact switch mechanism ofthe searchlight shall be tested by operating the switch for25 000 continuous

28、 cycles. A cycle shall consist of movementsfrom “OFF” position through the full “ON” and “FLASHING”positions and back to “OFF” position. The switch shall beoperated under normal electrical load conditions, and the lampand batteries shall be replaced as often as required to ensurethat the switch mech

29、anism is operating under normal loadthroughout the 25 000 cycles. Burning out of bulbs andbatteries during the test shall not constitute failure of this test.Failure of the switch to complete 25 000 cycles shall constitutefailure of this test.7.5 Vertical DropThe searchlight, when mounted to alifebo

30、at, shall be able to withstand a vertical drop test of thelifeboat with forces of 10 g and a side impact test of the lifeboatwith forces of 20 g.8. Packaging and Package Marking8.1 Product MarkingEach searchlight conforming to allthe requirements in this specification shall be marked with thename, b

36、ance withMIL-STD-105D, is provided. An Acceptable Quality Level(AQL) of 1 % defective for the operational test and the switchleakage test, and an AQL of 4 % for any of the otherrequirement or test specified shall be provided.
