    1 Scope

    1.1 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 in accordance with applicable requirements and tests for that component or product.

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

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

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

    1.5 This test procedure does not cover:

    a)    Mechanisms of ignition from external sources, such as static electricity, lightning, or other factors not related to the apparatus under test;

    b)    Apparatus based on the use of high voltage electrostatic principles;

    c)    The deterioration of external wiring; or

    d)    Connections installed in accordance with applicable installation standards.

    1.6 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, electric shock, or injury to persons shall be evaluated using the appropriate additional component and end-product requirements as required 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 is not judged to comply with this Standard. Where appropriate, revision of requirements are proposed and adopted in conformance with the methods employed for development, revision, and implementation of this Standard.
