34、S - UL 1112 FOREWORD A. This Standard contains basic requirements for products covered by Underwriters Laboratories Inc. (UL) under its Follow-Up Service for this category within the limitations given below and in the Scope section of this Standard. These requirements are based upon sound engineerin
35、g principles, research, records of tests and field experience, and an appreciation of the problems of manufacture, installation, and use derived from consultation with and information obtained from manufacturers, users, inspection authorities, and others having specialized experience. They are subje
36、ct to revision as further experience and investigation may show is necessary or desirable. B. The observance of the requirements of this Standard by a manufacturer is one of the conditions of the continued coverage of the manufacturers product. C. A product which complies with the text of this Stand
37、ard will not necessarily be judged to comply with the Standard if, when examined and tested, it is found to have other features which impair the level of safety contemplated by these requirements. D. A product employing materials or having forms of construction differing from those detailed in the r
38、equirements of this Standard may be examined and tested according to the intent of the requirements and, if found to be substantially equivalent, may be judged to comply with the Standard. E. UL, in performing its functions in accordance with its objectives, does not assume or undertake to discharge
39、 any responsibility of the manufacturer or any other party. The opinions and findings of UL represent its professional judgment given with due consideration to the necessary limitations of practical operation and state of the art at the time the Standard is processed. UL shall not be responsible to
40、anyone for the use of or reliance upon this Standard by anyone. UL shall not incur any obligation or liability for damages, including consequential damages, arising out of or in connection with the use, interpretation of or reliance upon this Standard. F. Many tests required by the Standards of UL a
41、re inherently hazardous and adequate safeguards for personnel and property shall be employed in conducting such tests STD-UL L332-ENGL 1997 9275795 07137530 2b0 I SEPTEMBER 5,1997 MARINE ELECTRIC MOTORS AND GENERATORS - UL 1112 5 INTRODUCTION I Scope 1.1 These requirements cover engine-cranking moto
42、rs, outdrive-tilt motors, power trim-tab motors, generators, and alternators rated less than 50 volts direct current. I .2 The products covered by these requirements are intended for installation and use in accordance with the applicable requirements of the Standard for Fire Protection of Pleasure a
43、nd Commercial Motor Craft, NFPA 302, or the United States Coast Guard. I .3 The requirements also cover components, such as cranking motor solenoids, generator or alternator voltage regulators, and connecting wiring provided by the product manufacturer. 1.4 These requirements cover nonignition-prote
44、cted components that are intended to be mounted outside of spaces requiring ignition-protected equipment and are marked accordingly see 18.1 (e), as well as ignition-protected components. 1.5 A product that contains features, characteristics, components, materials, or systems new or different from t
45、hose 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
46、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 meth
47、ods employed for development, revision, and implementation of this Standard. 2 Glossary 2.1 For the purpose of this standard, the following definitions apply. 2.2 CRANKING MOTOR (STARTER) - A high torque motor integrally mounted on the engine and intended to turn the engine over at a rotational spee
48、d sufficient for starting purposes. 2.3 FULLY CHARGED (BATTERY) - A condition resulting when the electrolyte of a battery is at: a) The full charge specific gravity specified by the manufacturer; and b) The maximum liquid level. 2.4 IGNITION-PROTECTED PRODUCT - A product constructed so that: a) A fl
49、ammable hydrocarbon mixture surrounding it is not ignited if a normally occurring electrical arc, spark, or heat source ignites the flammable hydrocarbon mixture inside the product; b) The electrical arc, spark, or heat source has insufficient energy to ignite the flammable mixture; or c) The source of ignition is hermetically sealed from the surrounding mixture. An ignition-protected product does not necessarily comply with the requirements for an explosion-proof product as applied to U.S. Coast Guard inspected vessels or as defined by the N
