标准范围

ISO 25862:2009给出了关于导航和转向用船用磁罗盘、罗盘和方位读数装置的构造和性能的要求。根据船舶的设计，规定了两种类型的罗盘。ISO 25862:2009适用于充液磁罗盘:根据现行法规，用于船舶在海上航行中的航行和转向目的；具有直读系统；其可以是反射型、投影型或透射型。在ISO 25862:2009的上下文中，磁罗盘是由定向系统组成的仪器，定向系统由碗内的单个枢轴支撑，碗内完全充满液体，并且支撑在碗内或碗外的万向节中。ISO 25862也涵盖了不带万向架的指南针:2009;有关万向节的要求不适用于此类罗盘。ISO 25862:2009适用于《国际海上人命安全公约》适用的所有船舶（从事国际航行的总吨位W 150吨的船舶和不从事国际航行的总吨位W 500吨的船舶），所有不适用《国际海上人命安全公约》而装有A类或B类磁罗盘的船舶，以及装有B类磁罗盘的救生艇/救助艇（如附件H所规定）。ISO 25862:2009不适用于:干卡罗盘，根据与上述不同的原理设计的指南针类型或不符合给出的描述，或手持指南针。并对罗经的检测认证、船舶定位和偏差调整提出了要求。ISO 25862:2009统一（即取消和取代）ISO 449、ISO 613、ISO 694、ISO 2269和ISO 10316。

ISO 25862:2009 gives requirements regarding construction and performance of marine magnetic compasses for navigation and steering purposes, binnacles and azimuth reading devices.According to the design of the ship, two types of binnacle are specified.ISO 25862:2009 applies to liquid-filled magnetic compasses:

• intended for ship's navigation and steering purposes in sea navigation according to regulations in force;
• having a direct reading system;
• which may be of the reflecting, projecting or transmitting types.

In the context of ISO 25862:2009, a magnetic compass is an instrument consisting of a directional system supported by a single pivot inside a bowl which is completely filled with liquid, and which is supported in gimbals inside or outside the bowl. Compasses without gimbals are also covered by ISO 25862:2009; the requirements relating to gimbals do not apply to such compasses.ISO 25862:2009 applies to

• all ships to which SOLAS applies (ships of gross tonnage W 150 t, engaged on international voyages and ships of gross tonnage W 500 t not engaged on international voyages) fitted with class A magnetic compasses,
• all ships to which SOLAS does not apply, fitted with the class A or class B magnetic compasses, and
• lifeboats/rescue boats fitted with a class B magnetic compass (as specified in Annex H).

ISO 25862:2009 does not apply to:

• dry card compasses,
• types of compass designed on principles different from those stated above or not complying with the descriptions given, or
• hand bearing compasses.

The requirements for the testing and certification, positioning in ships and the deviation adjustment of compasses are also given.ISO 25862:2009 unifies (i.e. cancels and replaces) ISO 449, ISO 613, ISO 694,ISO 2269 and ISO 10316.
