DIN ISO 25862

Abstract

This International Standard gives requirements regarding construction and performance of marine magnetic compasses for navigation and steering purposes, binnacles and azimuth reading devices. <br>According to the design of the ship, two types of binnacle are specified. <br>This International Standard applies to liquid-filled magnetic compasses: <br>&#8212; intended for ship's navigation and steering purpose in sea navigation according to regulations in force; <br>&#8212; having a direct reading system; <br>&#8212; which may be of the reflecting, projecting or transmitting types. <br>In the context of this International Standard, 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 this International Standard; the requirements relating to gimbals do not apply to such compasses. <br>This International Standard applies to <br>&#8212; 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, <br>&#8212; all ships to which SOLAS does not apply, fitted with the class A or class B magnetic compasses, and <br>&#8212; lifeboats/rescue boats fitted with a class B magnetic compass (as specified in Annex H). This International Standard does not apply to: <br>a) dry card compasses, <br>b) types of compass designed on principles different from those stated above or not complying with the descriptions given, or <br>c) hand bearing compasses. <br>The requirements for the testing and certification, positioning in ships and the deviation adjustment of compasses are given in the Annexes.
