UL 1500

This test procedure covers the basic test methods for determining ignition-protection and is not to be considered as a test standard that will determine the acceptability of a product or component for use in marine service. The acceptability of a product or component in the intended application is judged i n accordance with applicable requirements and tests for that component or product.

This test procedure does not cover explosion-proof or intrinsically safe equipment as required by the U. S. Coast Guard and a pplied to U. S. Coast Guard inspected vessels or as defined in the National Electrical Code, ANSI/NFPA No. 70.

Products and components classified as ignition-protected are intended to be installed and used i n accordance with the applicable requirements to the U. S. Coast Guard, the Fire Protection Standard fo r Pleasure and Commercial Motor Craft, ANSI/NFPA No. 302, and the American Boat and Yacht Council, Inc.

This test procedure does not cover ignition-protection procedures for products or components that may operate in hydrogen and air mixtures.

This test procedure does not cover:

• Apparatus based on the use of high-voltage electrostatic principles;
• The deterioration of external wiring; or
• Connections installed in accordance with applicable installation standards.

A product that contains features, characteristics, components, materials, or systems new or different from those in use when the Standard was developed, and that involves a risk of fire, electric shock, or injury to persons, shall be evaluated using the appropriate additional component and end-product requirements as determined necessary to maintain the level of safety for the user of the product as originally anticipated by the intent of this Standard.
