20、IGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION ORDISTRIBUTION WITHOUT PERMISSION FROM ULPART I ALL FIXTURESINTRODUCTION1 Scope1.1 These requirements apply to incandescent and fluorescent marine lighting fixtures rated 36 volts(nominally) or less using an AC or DC source of power.1.2 The lig
21、hting fixtures covered by these requirements are intended for installation and use inaccordance with the applicable requirements of the U.S. Coast Guard, the standards of the American Boatand Yacht Council, Inc., and the Standard for Fire Protection of Pleasure and Commercial Motorcraft,NFPA 302.1.3
22、 These requirements do not cover marine lighting fixtures for use in hazardous locations as defined inthe United States Coast Guard Electrical Engineering Regulations.1.4 These requirements also do not cover navigation lights, floating water lights, or emergency lights.1.5 A product that contains fe
23、atures, characteristics, components, materials, or systems new or differentfrom those covered by the requirements in this standard, and that involves a risk of fire or of electric shockor injury to persons shall be evaluated using appropriate additional component and end-productrequirements to maint
24、ain the level of safety as originally anticipated by the intent of this standard. Aproduct whose features, characteristics, components, materials, or systems conflict with specificrequirements or provisions of this standard does not comply with this standard. Revision of requirementsshall be propose
25、d and adopted in conformance with the methods employed for development, revision, andimplementation of this standard.2 General2.1 Units of measurement2.1.1 Values stated without parentheses are the requirement.

27、dard unless specifically noted otherwise.3 Components3.1 Except as indicated in 3.2, a component of a lighting fixture covered by this standard shall complywith the requirements for that component (see Appendix A for a list of standards covering componentsgenerally used in products covered by this s
28、tandard).3.2 A component is not required to comply with a specific requirement that:a) Involves a feature or characteristic not required in the application of the component in theproduct covered by this standard, orb) Is superseded by a requirement in this standard.3.3 A component shall be used in a
29、ccordance with its rating established for the intended conditions ofuse.3.4 Specific components are incomplete in construction features or restricted in performance capabilities.Such components are intended for use only under limited conditions, such as certain temperatures notexceeding specified li
30、mits, and shall be used only under those specific conditions.CONSTRUCTION4 General4.1 An external edge, projection, or corner shall be smooth, rounded, and not sufficiently sharp to causea laceration injury in intended use and maintenance.4.2 Means shall be provided for securely fastening the fixtur
31、e.4.3 Lock washers or other acceptable means shall be provided to reduce the likelihood of fasteningsbeing loosened due to vibration and shock.4.4 A non watertight fixture shall be provided with a means of draining the device to reduce the likelihoodof water accumulation around electrical components
32、.4.5 A fixture with glass or plastic enclosures made for installation in machinery spaces or other similarareas shall be protected with guards against inadvertent breakage (see Vibration Test, Section 20).4.6 Inverter ballasts, toroids, and other electronic components used in fluorescent fixtures sh
33、all be pottedor protected against dampness and vibration. Heat sinks shall be provided as required.SEPTEMBER 28, 2009 LOW VOLTAGE MARINE LIGHTING FIXTURES - UL 1149 7UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION ORDISTRIBUTION WITHOUT PERMISSION FROM UL4.7 A fluorescent fixture sha
34、ll be enclosed or electrically filtered so as not to interfere with radio receptionon the marine frequencies (see 33.2).4.8 A fixture shall be constructed for mounting directly to the mounting surface and not for suspension bya chain or other means that would allow movement or swinging of the fixtur
35、e.4.9 Acceptability of an adhesive shall be based on the following:a) The degree of reliance placed on the adhesive for securement in the construction of thefixture; andb) The applicable requirements in the Standard for Polymeric Materials Use in ElectricalEquipment Evaluations, UL 746C.5 Materials5
36、.1 The materials used for the construction of marine lighting fixtures shall have the mechanical,electrical, and chemical resistance characteristics appropriate for a marine environment.5.2 Housing brackets, trim, and other non current carrying parts shall be made of non ferrous metalalloys, ferrous
37、 metal alloys coated for protection against corrosion in a salt atmosphere, or nonmetallicmaterials.6 Enclosure6.1 A frame and enclosure shall be so formed and assembled that it will have the strength and rigiditynecessary to resist the abuses to which it is likely to be subjected, without increasin
38、g the likelihood of fire,electric shock, or injury to persons due to total or partial collapse, with resulting reduction of spacings,loosening or displacement of parts, or similar effects.6.2 Sheet metal of a frame or enclosure shall be formed from stock having a minimum thickness of 0.016inch (0.41
39、 mm) if of steel and 0.020 inch (0.51 mm) if of aluminum.Exception: Metal may be thinner if the part is investigated and found to have equivalent mechanicalstrength. Among the factors to be considered are size, shape, function, and resistance to distortion bothduring intended use and service and ant
40、icipated abuse.6.3 An enclosure or frame formed of a nonmetallic material may be employed if, upon investigation, thematerial exhibits properties equivalent to that addressed in 6.1. Among the factors to be considered are:a) Mechanical strength;b) Combustibility;c) Resistance to distortion at temper
41、atures likely to be encountered in service;d) Resistance to arcing; ande) Moisture absorption.For a polymeric enclosure, all these factors are to be considered with respect to thermal aging.SEPTEMBER 28, 2009LOW VOLTAGE MARINE LIGHTING FIXTURES - UL 11498UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FU
