船舶和海洋技术 - 充气救生设备的气体充气系统

[中文适用范围]： 本文件规定了充气式救生器具充气系统的性能和测试要求。 注：适用于符合经修订的 1974 年海上人命安全公约 ISOLAS 74) 和经 IMO 决议通过的经修订的 IMO 国际救生设备规则（LSA 规则）要求的充气救生设备。 海安会.48(66)。 本文件适用于由充气气体、气瓶阀门、气瓶操作头、高压软管以及泄压/传输、充气/放气和止回阀组成的气体充气系统。 本文件仅涉及使用气瓶中的压缩充气气体作为充气介质的系统。 国家对气瓶的资格、使用和测试的要求差异很大。 本文件中未涉及气瓶的此类要求，但假定气瓶满足适用监管机构的要求。 本文件中提到的系统属于救生设备中通常使用的类型，例如救生艇、海上疏散系统和救援装置。 ISO 12402-7 涉及个人救生设备（例如充气救生衣）中使用的系统。 [外文原描述]： This document specifies performance and testing requirements for gas inflation systems for inflatable life-saving appliances. NOTE It is suitable for inflatable life-saving appliances complying with the requirements of the 1974 Safety of Life at Sea Convention (SOLAS 74), as amended, and the IMO International Life-Saving Appliance Code (LSA Code) as amended, adopted by IMO Resolution MSC.48(66). This document applies to gas inflation systems which consist of an inflation gas, a gas cylinder valve, a gas cylinder operating head, high-pressure hoses, and pressure-relief/transfer, inflate/deflate and non-return valves. This document addresses only systems in which compressed inflation gas in cylinders is used as the inflation medium. National requirements for qualification, use, and testing of gas cylinders vary widely. Such requirements for gas cylinders are not addressed in this document, but it is presupposed that gas cylinders meet the requirements of the applicable regulatory bodies. The systems addressed in this document are of the type generally used in life-saving appliances, such as survival craft, marine evacuation systems, and means of rescue. Systems used in personal life-saving appliances, such as inflatable lifejackets, are addressed in ISO 12402-7.
