IEC 60092-507:2014规定了长度不超过50 m或总吨位不超过500总吨(GT)的小型船舶电气系统的设计、建造和安装要求。内陆水域或海上。它不适用于: a)仅配备电池的小型船舶，该电池为发动机启动和导航照明提供电路，由舷内或舷外发动机驱动的交流发电机充电。 b)船体长度小于24米的娱乐性船舶，需要符合娱乐性船舶指令94/25/EC附件1基本要求第5.3部分电气系统，但此类娱乐性船舶中在额定电压不超过AC 500 V下运行的三相交流电装置除外。 与上一版相比，第三版包含以下重大技术变更:a)该标准现在阐明了其对那些需要符合《休闲船指令》的休闲船电气装置的应用。 b)该标准规定了连接到低压交流岸上电源的小型船舶和休闲船的电流隔离方法的要求。 c)该标准包括适用于小型船舶的电力推进系统的设计指南和相关的安装要求。

IEC 60092-507:2014 specifies requirements for the design, construction and installation of electrical systems in small vessels, which have a length of up to 50 m, or which have a gross tonnage not exceeding 500 Gross Tonnes (GT), designed for use on inland waters or at sea. It is not intended to apply to:
a) small craft equipped only with a battery supplying circuits for engine starting and navigation lighting recharged from an inboard or outboard engine driven alternator.
b) recreational craft of less than 24 m hull length requiring to conform to the Recreational Craft Directive 94/25/EC Annex 1 Essential Requirements Part 5.3 Electrical systems, except for three-phase alternating current installations in such recreational craft which operate at a nominal voltage not exceeding AC 500 V. This third edition includes the following significant technical changes with respect to the previous edition:
a) The standard now clarifies its application for electrical installations in those recreational craft which require to conform to the Recreational Craft Directive.
b) The standard specifies requirements for methods of galvanic isolation for small vessels and recreational craft connecting to a low voltage AC shore supply.
c) The standard includes design guidance for electric propulsion systems suitable for small vessels and associated installation requirements.
