Materials that are nutrients for fungi shall not be used where it is practical to avoid the
19、m. Where used and not hermetically sealed, they shall be treated with a fungicidal agent acceptable to the procuring activity. However, if they will be used in a hermetically sealed enclosure, fungicidal treatment will not be necessary. 3.4 Design and construction. The light shall be so designed tha
20、t it will operate satisfactorily under all weather conditions and so constructed that no parts will work loose in service. It shall be built to withstand the strains, jars, vibrations, and other conditions incident to shipping, storage, installation, and service. The light shall be so constructed th
21、at adjustments and repairs can be easily made by the personnel of operating units and overhaul bases with tools normally available commercially. The light shall be so designed that weight is held to the minimum consistent with the necessary strength and rigidity. The exact shape and design are optio
22、nal provided all requirements specified herein are met. 3.4.1 Focus. The entire optical system shall be of the fixed prefocus type requiring no focusing at installation or in service. 3.4.2 Lens. The lens for class I light shall be in accordance with figure 1, of one piece construction, and shall ut

The lenses for class II and III lights shall be in accordance with figure 2 of
24、 one piece construction and shall be smooth external construction. The lenses shall be marked with an arrow and the words RUNWAY SIDE as indicated. The glass shall be type I, aviation white, in accordance with SAE AS25050, and class B, heat-resistant, in accordance with MIL-DTL-7989. 3.4.2.1 Shield.
25、 If the design of the lens requires shielding in order to limit the light emitted on the runway side, a suitable shield shall be attached to the lens. A shield, when used, shall be considered a part of the lens and shall be securely fastened to the lens so that no adjustment or positioning of the sh
26、ield is required when a lens is mounted upon any approved housing. The shield, when used, shall also serve as a reflector in order to improve the light distribution. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-DTL-5904E 5 3.4.3 Filters. Class
27、 I light filters, when required, shall be of class B, heat-resistant glass, in accordance with MIL-DTL-7989, and shall be in accordance with figure 3. The corners on the mounting flange of each nominal 180 filter shall be cut at an angle of 45 in order that the filter may be indexed by lugs which ar
28、e .188 inches wide by .156 inches high with a .094 inch radius at top. Filters shall be shipped separately and shall be of the color specified by the procuring activity. Two mounting clips in accordance with figure 3 and two number (no.) 8-32 x .375 machine screws of stainless steel shall be supplie

The class II light assembly shall be designed to utilize a 200 W, 6.6 amp halogen cycle lamp. The class III light assembly shall be d
32、esigned to utilize a 100 W, 6.6 amp, C-6 filament construction lamp. The class III lamp shall be equal to and interchangeable with GE Q200T4/CL. All lamps shall have a minimum average life cycle of 500 hours. Unless otherwise specified (see 6.2), the lamp shall not be furnished with the light. 3.4.5
33、 Socket. For class I light assemblies, the lamp socket shall be a ceramic, ventilated, medium-prefocus type having a rating of 1000 W, 250 volt (V), equal to and interchangeable with Amphenol Corporation PN 98-1. The socket shall accommodate lamps having base dimensions within the tolerances specifi
34、ed for the lamp. The class II and III light sockets shall accommodate lamps having base dimensions within the tolerances of lamps specified in 3.4.4. 3.4.6 Housing. The lens, filters, shield, and lamp shall be accurately and securely positioned by utilizing a lightweight aluminum housing. Four sprin
35、g clips as shown on figure 5 shall be used to secure the lens to the housing. Indexing lugs shall be located on the housing to engage the slots in the mounting flanges of the lens and filters. The indexing lugs shall be of sufficient size to limit the rotation of the lens and filters to not more tha
36、n 1. The lugs which index the lens shall not extend up into the mounting flange slots more than .188 inches after the light is assembled. The housing shall support the lens, filters, shield and lamp so that they are tilted 4 downward toward the runway side after the light has been leveled. A .125 in
37、ch rubber or synthetic rubber gasket shall separate the housing and the lens. All gaskets and other materials shall be of a type which will not emit smoke or vapor during rated current operations within the specified temperature range. The design of the housing shall be such that no ventilation is r
38、equired, condensation upon lens and filter is minimized, and drainage is provided to prevent the gradual accumulation of condensate. The upper portion of the housing shall contain the lens and filters and shall be readily separable from the lower portion for re-lamping by loosening one wing screw. U
39、pper and lower portions of the housing shall be properly indexed to insure aiming within the required tolerances. The lens and filters shall be securely clamped in place but shall be readily removable for maintenance. Four bosses, containing four equally spaced holes with centers located on a circle
40、 5.438 inches in diameter, shall be provide Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-DTL-5904E 6 for attachment of color filters. The holes shall be tapped to a depth of at least .375 inches for no. 8-32 screws. After installation, the low
41、er surface of the lens flange shall be approximately .094 inches below the upper surface of the bosses, and the lower surface of the color filter flange shall be approximately .250 inches below the upper surface of the bosses. All above apply to the class II and III light assemblies with exceptions
42、that the lens is secured with a band clamp, it is not necessary to tilt the light assembly 4 towards the runway, re-lamping is accomplished by removing the band clamp, and the four bosses do not apply to class II and III light assemblies. 3.4.6.1 Mounting. The housing shall be designed so that it ma
43、y be mounted upon an unthreaded mounting tube having an external diameter of 2.375 .035 inches. Two or three 1/4-20 round or fillet head, stainless steel set screws shall be installed in the housing for clamping the housing on the tube. When mounted upon the tube, the tube shall extend 2.125 .125 in
44、ches into the light. The class II and III light assemblies shall have the frangible coupling as part of the light base. The bottom of the light base shall be a 2.0 inch tapered pipe thread designed to fit into standard United States Air Force and FAA airport base plates and mounting stakes. 3.4.6.2
45、Horizontal adjustment. Horizontal adjustment of the light to any desired azimuth shall be obtained by rotating the housing on the mounting tube. 3.4.6.3 Leveling adjustment. The lower portion of the housing shall be designed to provide leveling of the light from any position not exceeding 4 for the
46、vertical. The leveling device shall be of the pivot type, adjustable by means of 3 or 4 screws. The screws shall be stainless steel size no. 8 or larger. The leveling device shall be independent of the horizontal adjustment. 3.4.6.4 Aiming. The housing shall provide a means for leveling and sighting
47、, designed to insure aiming of the light with sufficient accuracy so that the direction of the light beams will be in accordance with the requirements specified in 3.5.1. The leveling device may be an accurately formed surface upon which a carpenters level may be placed in two positions at right ang
48、les during installation. The sight may be any device or marks placed upon the light in such a manner as to provide accurate aiming by sighting at the next light in the row of runway lights. Removal of the lens and filters form the upper portion of the housing shall not be required during the levelin
49、g and aiming procedure. 3.4.7 Cord. A length of two-conductor, no. 16 American Wire Gauge (AWG), type SJ or OSJ rubber or synthetic rubber cord shall be connected to the bottom of the socket, and no portion of the cord shall extend up beside the socket where it would be exposed to excessive temperatures. A 2-pole, 600 V, 20 amp plug in accordance with style 1 of FAA AC 150/5345-26 shall be molded on the lower end of the cord. The length
