船舶和航海技术.船用磁罗盘和方位读数装置

[中文适用范围]： 本文件规定了用于导航和操舵目的的船用磁罗盘、罗经柜和方位读取装置的结构和性能要求。 指定了两种类型的罗经柜；给定船舶的适当类型由船舶的设计决定（参见第 5 条）。 本文件适用于充液磁罗经： ——用于船舶导航和海上航行操舵； ——具有直读系统； - 可以是反射型、投射型或透射型。 在本文中，磁罗盘是一种由定向系统组成的仪器，该定向系统由碗内的单个枢轴支撑，该碗完全充满液体并由碗内部或外部的万向节支撑。 然而，本文档还讨论了没有万向节的罗盘；与万向节相关的要求不适用于此类罗盘。 本文件适用于船上携带的磁罗经： a) 根据 ISOLAS 第 V 章要求携带标准罗经的所有船舶，A 级磁罗经； b) 符合 IMO 救生设备（LSA）规则并配备 B 级磁罗经的救生艇和救助艇； c) 上述 a) 和 b) 不适用但装有 A 级或 B 级磁罗盘的所有船舶。 本文件不适用于： a) 干卡罗盘； b) 设计原理与上述不同或不符合所给出描述的指南针类型；或 c) 手持罗盘。 船用磁罗经、方位读数装置和罗经柜的检测和认证要求见附件A、B、C和D。 船舶定位、安全距离的确定和罗经偏差调整的要求分别在附录 E、F 和 G 中给出。 救生艇/救助艇用磁罗盘的特殊要求见附录H。 [外文原描述]： This document specifies requirements for the construction and performance of marine magnetic compasses for navigation and steering purposes, binnacles and azimuth reading devices. Two types of binnacle are specified; the appropriate type for a given vessel is determined by the design of the ship (see Clause 5). This document applies to liquid-filled magnetic compasses: — intended for use in ship's navigation and steering in sea navigation; — having a direct reading system; and — which can be of the reflecting, projecting or transmitting types. In the context of this document, a magnetic compass is an instrument consisting of a directional system supported by a single pivot inside a bowl that is completely filled with liquid and supported by gimbals inside or outside the bowl. However, this document also addresses compasses without gimbals; the requirements relating to gimbals do not apply to such compasses. This document applies to magnetic compasses carried on board: a) all ships required to carry a standard compass as per SOLAS Chapter V, the Class A magnetic compass; b) lifeboats and rescue boats as per the IMO Lifesaving Appliances (LSA) Code, fitted with the Class B magnetic compass; and c) all ships to which a) and b) above do not apply, but which are fitted with a Class A or B magnetic compass. This document does not apply to: a) dry card compasses; b) types of compass designed on principles different from those stated above or not complying with the descriptions given; or c) hand bearing compasses. The requirements for the testing and certification of marine magnetic compasses, azimuth reading devices and binnacles are given in Annexes A, B, C, and D. The requirements for the positioning in ships, the determination of safe distances and the deviation adjustment of compasses are given in Annexes E, F and G, respectively. The special requirements of the magnetic compass for lifeboats/rescue boats are given in Annex H.
