There shallbe a means provided to lock the searchlight in any desiredposition without the use of tools (vertically and horizontally).5.3 The searchlight shall be capable of illuminating a lightcol

10、ored object at night at 55 ft (180 m). The searchlight shallproject a beam of light of not less than 5.5 ft (18 m) in diameterat a distance of 55 ft from the light source. The edge of thebeam shall be a point where the intensity of the light is 10 %of the maximum intensity. The light source shall ha

11、ve acandlepower rating of no less than 350 000 cd.5.4 The searchlight shall be capable of being operated fornot less than3hofcontinuous use and6hofintermittent use.5.5 The lamp used in the searchlight shall be of theincandescent, quartz, or other type which would allow forinstant start. The lamps sh

12、all be rated for 12 V.5.6 Each searchlight shall be watertight. The searchlightshall show no leakage of water following the test methodprescribed in 7.1.5.7 Each searchlight shall be wired with a 6-ft (2-m) lengthof rubber jacketed hard service flexible cord, unless otherwisespecified in 8.3. The co

13、nductor 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 gland orconnections. The free

14、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.1This specification is under the jurisdiction of ASTM Committee F25 on Shipsand Marine Technology and

Workmanship, Finish, and Appearance6.1 Searchlights shall be of sturdy construction, and freefrom mechanical, electrical, or other imperfections or defectswhich materially affect appearance or which may af

18、fect quality,reliability, or serviceability.6.2 The finished searchlight shall not contain rough edges,burrs, or other disfigurations and shall be clean, free from rust,tool marks, and other injurious defects.7. Test Methods7.1 WatertightnessThe searchlight shall be submerged ina saltwater solution

19、(1.04 sp gr) to a depth of 3 ft (0.9 m) of60F (16C) for 2 h.The light will then be subjected to the testsof 7.2.1 and be in perfect working order.7.2 Environmental:7.2.1 Operational TestThe searchlight shall be operatedcontinuously for3hatrated voltage in an ambient temperatureof 77F (25C) and be op

20、erational after being subjected to thewatertightness test of 7.1. The searchlight shall then beoperated intermittently. The intermittent time periods shall be15 min “ON” and 5 min “OFF” for a total 6-h period. Thesetests shall be repeated three times.7.2.2 Impact:7.2.2.1 Test ConditionsThe searchlig

21、ht shall be placed ina cold chamber at 40 6 5F (40 6 3C) for 2 h. With thesearchlight stabilized at this temperature, it shall be immedi-ately subjected to the low- and high-impact tests specified in7.2.2.2 and 7.2.2.3. The point of impact shall be applied to theoutside of the case at a point midway

22、 between the ends of thecase at 4 points 90 apart and the back plate.7.2.2.2 Low ImpactThe searchlight shall be subjected to a12 in.lbf (1.3 J) impact using a 1-lb (0.5-kg) steel ball at eachof the points of impact specified in 7.2.2.1. The searchlightshall then be subjected to the watertightness te

23、st (see 7.1).There shall be no evidence of breakage from impact and noevidence of moisture shall be found in the case.7.2.2.3 High ImpactThe searchlight, after passing thelow-impact 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.l

24、bf (2.3 J) impact using a 1-lb (0.5-kg)steel ball at each of the points of impact specified in 7.2.2.1.There shall be no evidence of damage to the case or the lens.7.3 Test for Light ProjectionThe beam spread of thesearchlight shall be shown to meet the calculations contained inthe IES Lighting Hand

25、book.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 cycles. A cycle shall consist of movementsfrom “OFF” position through the full “ON” and “FLASHING”positions and back to “

26、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 mechanism is operating under normal loadthroughout the 25 000 cycles. Burning out of bulbs andbatteries during the test shall

27、not constitute failure of this test.Failure of the switch to complete 25 000 cycles shall constitutefailure of this test.7.5 The searchlight, when mounted to a lifeboat, shall beable to withstand a vertical drop test of the lifeboat with forcesof 10 g and a side impact test of the lifeboat with forc

28、es of 20g.8.
