1.1 本规范规定了船用交流电源电路用浪涌抑制器的性能要求。 1.2 浪涌抑制器应是一种保护装置，用于通过放电、内部消散、旁路浪涌电流或其组合来限制设备上的电压瞬变，防止跟随电流持续流向地面，并能够重复这些功能。 1.3 本规范涵盖的浪涌抑制器可能由单个电路元件组成，也可能是使用多个抑制装置的混合装置。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

1.1 This specification establishes performance requirements of surge suppressors for use on shipboard ac power circuits. 1.2 Surge suppressor shall be a protective device for limiting voltage transients on equipment by discharging, dissipating internally, bypassing surge current, or a combination thereof and which prevents continued flow of follow current to ground and is capable of repeating these functions. 1.3 Surge suppressors covered by this specification may consist of a single circuit element or may be a hybrid device using several suppression devices. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
