19、1 5October2001ISO 316:(0002)E iv Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body inte
20、rested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnica
21、l Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publicati
22、on as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all suc
23、h patent rights. International Standard ISO 613 was prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee SC 6, Navigation. This second edition cancels and replaces the first edition (ISO 613:1982), which has been technically revised. 4egaP ENISO613:2001 5October2001INT
24、ENRATIONAL TSANDADR ISO 316:(0002)E 1 Ships and marine technology Magnetic compasses, binnacles and azimuth reading devices Class B 1 Scope This International Standard gives general requirements regarding construction and performance for magnetic compasses, binnacles and azimuth reading devices, cla
25、ss B. In addition, this International Standard includes general requirements regarding construction and performance for hand-bearing compasses. This International Standard applies to liquid-filled magnetic compasses, with or without gimbals, intended for sea navigation on board ships for “restricted
26、 service and life boats “ according to the regulations in force; with a sealed or non-sealed bowl; having a direct reading system; which may be of the reflecting, projecting or transmitting types. This International Standard does not apply to a) dry card compasses; b) types of compass designed on pr
27、inciples different from those stated above or not complying with the descriptions given. NOTE As ISO 14227 (7 in the bibliography) covers magnetic compasses for use in small craft of hull length up to 24 m, this International Standard does not have any provision for them. 2 Normative reference The f
28、ollowing normative document contains provisions which, through reference in this text, constitute provisions of this International Standard. For a dated references, subsequent amendments to, or revisions of, the publications do not apply. However, parties to agreements based on this International St
29、andard are encouraged to investigate the possibility of applying the most recent edition of the normative document indicated below. For an undated reference, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International S

31、ng apply. 3.1 azimuth reading device device which is able to take the azimuth of celestial bodies and bearings of distant objects as an azimuth circle, an azimuth mirror, etc. 3.2 magnetic compass instrument consisting of a directional system supported by a single pivot inside a bowl which is comple
32、tely filled with liquid, and which may be supported in gimbals inside or outside the bowl 4 Magnetic compasses 4.1 Construction and material 4.1.1 The magnets used in the directional systems of magnetic compasses shall be of a suitable magnetic material having a high remanence and a coercivity of at
33、 least 18 kA/m. All other materials used in magnetic compasses, other than transmitting compasses, shall be of non-magnetic material. 4.1.2 The compass shall be fitted with at least one lubber mark, indicating the direction of the ships head (the main lubber mark). Additional lubber marks are permis
34、sible. The lubber mark shall be of such design as to allow the compass to be read from the steering position when the bowl is tilted 10 in the case of a gimbal compass or 30 in other cases. 4.1.3 The gimbal axes shall be mutually perpendicular within a tolerance of not more than 2. For compasses wit
35、hout gimbals, which are also covered by this International Standard, the requirements relating to gimbals do not apply. 4.1.4 Within the temperature range 20C to 60C: a) the compass shall operate satisfactorily; b) the liquid in the compass bowl shall remain clear and free from bubbles and neither e
36、mulsify nor freeze; c) there shall be neither inward leakage of air nor outward leakage of liquid; no bubble shall form in a compass unless it is specially provided to compensate for expansion; A bubble provided in a compass to compensate for expansion shall not disturb the functioning and reading o
37、f the compass. d) the internal paint shall not blister, crack or discolour appreciably; e) the supporting force shall be such that the directional system always remains in contact with its pivot; f) the material of the compass card shall not distort. 4.1.5 The compass bowl shall be balanced so that
38、its verge ring or top glass cover settles in the horizontal plane to within to 2 when the gimbal ring is fixed in a horizontal position; this shall be so whether the azimuth reading device or magnifying glass is in place or not.

39、edevr 3 4.2 Mounting 4.2.1 The bowl of the compass shall be mounted so that the verge ring remains horizontal when the binnacle is tilted 30 in any direction and in such a manner that the compass cannot be dislodged under any conditions of sea or weather. 4.2.2 In compasses in which no supporting gi
40、mbal is provided, the freedom of the card shall be 30 in all directions. 4.3 Directional system 4.3.1 Moment of inertia The moment of inertia of the directional system shall be approximately the same about all horizontal axes passing through the point of support on the pivot jewel. 4.3.2 Suspension
41、The directional system shall be retained in position by suitable means and remain free when the bowl is tilted 10 in any direction. 4.3.3 Settling time Following an initial deflection of the card of 90 from the magnetic meridian, the time taken to return finally to within 1 of the magnetic meridian,
42、 shall not exceed 240/ H at a temperature of 20 C 3C,whereH is the horizontal component of the magnetic flux density in microteslas (T) at the place of testing. 4.4 Graduation 4.4.1 Compass card The compass card shall be graduated in equal intervals of not more than 5 and numbered at intervals of no
43、t more than 30, starting from North in the clockwise direction as viewed from above, and numbered at intervals of not more than 30. The cardinal points shall be indicated by the capital letters N, S, E and W; the intermediate points may also be marked. Alternatively, the North point may be indicated
44、 by a suitable symbol. 4.4.2 Readability by the helmsman If a steering compass is provided for the helmsman, it shall be possible for a person with normal vision to read at a distance of 1,0 m, in both daylight and artificial light, those graduations on the card which are contained within a sector o
45、f not less than 15 to each side of the lubber mark. The use of a magnifying glass is permitted. For reflecting and projecting compasses, the lubber mark shall be visible and a sector of 15 on the card on each side of the lubber mark shall be readable by a person with normal vision at a distance of 1
46、 m from the periscope tube. 4.5 Accuracy 4.5.1 Directional error The directional error shall not exceed 1,5 on any heading. 4.5.2 Lubber error The lubber error shall not exceed 1.
