12、ber bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmen
13、tal and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance
14、are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention i
15、s drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

28、lockwise through 360.Note 2 to entry: When the gyro-compass equipment is tested on the test stand, this “true heading” is regarded as the true heading of the lubber line. Where a gyro-compass has the facility of introducing a correction by moving the lubber line, the correction is set for the local

35、he purpose of taking a bearing.4.2 Continuous operationThe equipment shall be capable of continuous operation under conditions of vibration, humidity, change of temperature, and variations of the power supply, as specified in 6.10.4.3 Bearing repeater compass1)For those crafts which are required to
36、carry a bearing repeater compass, the construction of these shall be as follows.a) The bearing repeater compass shall be designed to be fitted with an azimuth-reading device.b) A gimbal mechanism shall be provided to enable the bearing repeater compass card to be held horizontally against the crafts
37、 motion.4.4 Graduation and digital displayThe compass card shall be graduated at equal intervals of 1 or a fraction thereof. The graduation error shall be less than 0,2. A numerical indication shall be provided at least at every 10, starting from 000 clockwise through 360.A digital display may be pr
38、ovided. When a digital display is provided, the course shall be displayed as three digits plus, optionally, a fourth digit indicating tenths of a degree.

40、 way to facilitate installation so that the lubber line lies in a vertical fore and aft plane of the craft or parallel. Where a gyro-compass has the facility of introducing a correction by moving the lubber line, the correction during installation shall be set to zero.1) Advice to ship surveyors for
41、 installation on board craft is given in normative annex A. ISO 2014 All rights reserved 3BS ISO 16328:2014ISO 16328:2014(E)If such marks or identifications are not in the same vertical plane as the uncorrected lubber line, then the horizontal angular relationship between them shall be clearly indic
42、ated in the manufacturers installation instruction.4.8 InstallationThe master compass shall be installed or adjusted in a craft with the fore and aft datum lines parallel to the crafts fore and aft datum line to within 0,5.
