1 Scope

1.1 These requirements are supplementary to other applicable requirements in the Standard for Luminaires, UL 1598 and other luminaire standards, to qualify the luminaire for installation on marine vessels. References to requirements in UL 1598 are in italics for easy identification.

[Informational note: Most fixed installation luminaires are evaluated for compliance with the Standard for Luminaires, UL 1598. References to requirements in UL 1598 are in italics for easy identification. Luminaires evaluated to UL 2108, Standard for Low Voltage Lighting Systems, and UL 924, Standard for Emergency Lighting Equipment, are also eligible to apply the supplementary UL 1598A requirements.]

1.2 These requirements apply to luminaires for installation on marine vessels utilizing grounded systems in accordance with the United States Coast Guard Electrical Engineering Regulations 46 CFR, Parts 110 – 113, Subchapter J and, insofar as it applies, the National Electrical Code, ANSI/NFPA 70, and the Recommended Practice for Electrical Installations on Shipboard, IEEE 45.

1.3 These requirements do not apply to marine lighting luminaires for use in hazardous locations, as defined in the National Electrical Code, ANSI/NFPA 70, emergency lighting marine luminaires, or low voltage marine luminaires (less than 50 volts) supplied solely by a battery, transformer, converter, or similar power supply source.

1.4 A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirements in this standard, and that involves a risk of fire or of electric shock or injury to persons shall be evaluated using appropriate additional component and end-product requirements to maintain the level of safety as originally anticipated by the intent of this standard. A product whose features, characteristics, components, materials, or systems conflict with specific requirements or provisions of this standard does not comply with this standard. Revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this standard.
