SCOPE: This SAE Aerospace Recommended Practice (AR
5、P) provides minimum standards and environmental design requirement recommendations for lighting and control in galley areas. It also addresses electrical shock hazard in galley areas. 1.1 Purpose: The purpose of this recommended practice is to provide minimum standards for the illumination of galley
6、s (buffets) and for the location of lighting controls within the galley area of passenger transport aircraft. 2. DEFINITION: Galley lighting is the lighting that is provided within the galley area. Galley lighting should provide sufficient illumination for the preparation and serving of food, the re
7、ading of instruction manuals, and the identification and operation of the various controls and equipment located in the galley. 3. RECOMMENDATIONS: 3.1 Lighting Levels: 3.1.1 Average of 53.8 1x (5.0 ft-c) of illumination should be provided on the floor of the galley area. Copyright SAE International

9、0.76 1x (1.0 ft-c) should be provided on the floor of deep compartments, such as ovens, and storage bins, which must be inspected. 3.1.4 Average of 53.8 1x (5.0 ft-c) of illumination should be provided on all controls, operating instructions, and placards. 3.1.5 The galley area lighting should be pr
10、ovided with dimming controls, either continuous or stepped dimming, to reduce the illumination while operating under dark conditions. 3.1.6 The color of the galley light sources should be white. 3.2 General: 3.2.1 Lighting Location: Light sources should be carefully located to minimize the casting o
11、f shadows on work areas by personnel occupying normal work positions. Light from the galley area should be confined to that area by directional light sources or by curtains around the galley area. Light sources should be located and trim materials selected to minimize glare in the eyes of an attenda
12、nt working in the galley. 3.2.2 Controls: All controls within the galley area should be so located or protected as to prevent injury to an attendant in the event of a violent airplane movement. 3.2.2.1 All lighting controls within the galley area should be placed on a single control panel and locate
13、d within convenient reach of the attendant. Individual controls shall be arranged to conform generally to the physical location of the light sources. Light controls for continuous dimming shall rotate clockwise to increase intensity and shall provide an “off“ position at the extreme of counter-clock
14、wise rotation. For step dimming or on/off control, the toggle controls shall be full bright/on in the up position. 3.2.2.2 Incandescent lamps should be operated at not more than 90% rated voltage to extend lamp life. Operation at 90% rated voltage will result in four times rated lamp life. Long life
15、 lamps (rated for 2000 h or more) should be operated at not more than 95% rated voltage. 3.2.2.3 Ballast and transformers should contain replaceable fuses or other circuit protectors to prevent overheating and smoke. If fuses are used, replacement fuses should be available. 3.2.3 Fixture Temperature
16、: While installed, no exposed lighting fixture surface should exceed a stabilized temperature of 65.5C (150F) with an ambient temperature of 23.8C (75F).

17、-,-SAE ARP712 Revision B - 3 - 3.2.4 Fixture Bonding: All exposed metal surfaces should be electrically bonded to airframe structure to prevent electrical shock hazard to personnel. 3.2.4.1 If input voltage to the fixture exceeds 30 V, an electrical ground should be provided. 3.2.5 Maintenance: Cons
18、istent with general galley design, lighting fixtures should be designed and fabricated to provide smooth, easily cleanable surfaces with a minimum of cracks and crevices. 3.2.6 Material and Workmanship: All galley lighting fixtures and equipment should be designed and qualified for reliable operatio
19、n, under the applicable aircraft environment, throughout the life of the aircraft. Materials and workmanship should be consistent with the best manufacturing practice for aircraft equipment and accessories. Design should be such that noise from vibrating parts is minimized. 3.2.7 Lamp Replacement: A
20、ll lamps should be readily replaceable without the use of special tools. When opened for re-lamping, the replacement lamp part number should be clearly visible in all lighting fixtures. The manufacturers name and part number shall be clearly visible to maintenance personnel, on all lighting fixtures
21、. The type of lamps used in the galley should be consistent with the type of lamps used throughout the airplane. 3.2.8 EMI: All lighting fixtures should meet the applicable electromagnetic interference requirements of Radio Technical Commission for Aeronautics (RTCA) Document No. DO-160B. 3.2.9 Envi
22、ronmental Conditions: Radio Technical Commission for Aeronautics performance should be determined and testing accomplished in accordance with applicable environmental conditions of RTCA Document No. DO-160B.

24、 a) All electric circuits isolated from the case. b) All electrical terminations covered to prevent inadvertent shorting or personnel contact. c) All metal components electrically connected to a bonding stud so that chasis to (earth) ground may be accomplished with a separate wire. 4. OTHER CONSIDER
25、ATIONS: The lighting should comply with the design goals and other considerations as recommended in AIR512A.
