3、ard contains revisions through and including March 8, 2007.Summary of TopicsThis revision to UL 1500 includes revising the ignition of internal gas/air mixture test proceduresin Section 9.UL Standards for Safety are developed and maintained in the Standard Generalized Markup Language(SGML). SGML - a
4、n international standard (ISO 8879-1986) - is a descriptive markup language thatdescribes a documents structure and purpose, rather than its physical appearance on a page. Due toformatting differences resulting from the use of ULs new electronic publishing system, please note thatadditional pages (o
5、n which no requirements have been changed) may be included in revision pages dueto relocation of existing text and reformatting of the Standard.Text that has been changed in any manner is marked with a vertical line in the margin. Changes inrequirements are marked with a vertical line in the margin
6、and are followed by an effective date noteindicating the date of publication or the date on which the changed requirement becomes effective.The revised requirements are substantially in accordance with ULs Proposal(s) on this subject datedFebruary 1, 2007.The revisions dated March 8, 2007 include a
7、reprinted title page (page1) for this Standard.The UL Foreword is no longer located within the UL Standard.

34、DUCTION ORDISTRIBUTION WITHOUT PERMISSION FROM ULINTRODUCTION1 Scope1.1 This test procedure covers the basic test methods for determining ignition protection and is not to beconsidered as a test standard that will determine the acceptability of a product or component for use inmarine service. The ac
35、ceptability of a product or component in the intended application is judged inaccordance 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 theU. S. Coast Guard and applied to U. S
36、. Coast Guard inspected vessels or as defined in the NationalElectrical Code, ANSI/NFPA No. 70.1.3 Products and components classified as ignition protected are intended to be installed and used inaccordance with the applicable requirements to the U. S. Coast Guard, the Fire Protection Standard forPl
37、easure 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 thatmay operate in hydrogen and air mixtures.1.5 This test procedure does not cover:a) Mechanisms of igni
38、tion from external sources, such as static electricity, lightning, or otherfactors not related to the apparatus under test;b) Apparatus based on the use of high voltage electrostatic principles;c) The deterioration of external wiring; ord) Connections installed in accordance with applicable installa
39、tion standards.1.6 A product that contains features, characteristics, components, materials, or systems new or differentfrom those covered by the requirements in this Standard, and that involves a risk of fire, electric shock, orinjury to persons shall be evaluated using the appropriate additional c
40、omponent and end-productrequirements as required to maintain the level of safety as originally anticipated by the intent of thisStandard. A product whose features, characteristics, components, materials, or systems conflict withspecific requirements or provisions of this Standard is not judged to co
41、mply with this Standard. Whereappropriate, revision of requirements are proposed and adopted in conformance with the methodsemployed for development, revision, and implementation of this Standard.MARCH 8, 2007 IGNITION-PROTECTION TEST FOR MARINE PRODUCTS - UL 1500 5UL COPYRIGHTED MATERIAL NOT AUTHOR

43、imit (UEL) that will explode if ignitedby any means. For purposes of this standard, mixtures of gasoline and air and diesel fuel and airbetween the LEL and UEL will be considered as hydrocarbon mixtures covered by the tests withpropane and air.2.3 HERMETICALLY SEALED A void that is completely sealed
44、 by soldering, brazing, welding, fusionof glass, or the like, to prevent the entrance or escape of air or gas when changes in atmosphericpressure or ambient temperature, or both, occur.2.4 IGNITION PROTECTED A device or component constructed so that:a) A flammable hydrocarbon mixture surrounding the
45、 device will not be ignited if a normallyoccurring electrical arc, spark, or heat source ignites a flammable hydrocarbon mixture insidethe device;b) The electrical arc, spark, or heat source has insufficient electrical or heat energy to ignite theflammable mixture; orc) The source of ignition is her
46、metically sealed from the surrounding mixture.An ignition-protected device does not necessarily comply with the requirements for an explosion-proofdevice as applied to U.S. Coast Guard inspected vessels or as defined the the National Electrical Code1996 Edition; Errata No. 1, ANSI/NFPA 70.2.5 IGNITI
47、ON SOURCE Any electrical contacts, commutator or brush assembly, or collector ring andbrushes that may produce electrical arcs of ignition capable energy; a resistor or other component thatmay operate at a temperature sufficient to ignite a flammable mixture; or two materials that may strikeeach oth
48、er and produce a spark having sufficient energy to ignite a flammable mixture.2.6 NONSPARKING The condition resulting when moving parts of a device are unlikely to producesparks of sufficient energy to ignite a flammable hydrocarbon mixture if the parts strike.2.7 NORMAL OPERATING CONDITION Any oper
49、ating conditions of the device, including overloadup to 400 percent (circuit breakers, switches, and the like) and a stalled rotor condition for any motorwith the circuit protected by an overcurrent protective device specified by the product manufacturer.MARCH 8, 2007IGNITION-PROTECTION TEST FOR MARINE PRODUCTS - UL 15006UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION ORDISTRIBUTION WITHOUT PERMISSION FROM UL3 General3.1 A component or apparatus that is to be
