The work of preparing

16、 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, governmental and non-governmental, in liais

17、on with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of te

18、chnical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is dr

19、awn 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.

21、cables and lines for anchoring, mooring and towing small craft. It does not specify the requirement for any strong point from which the craft can tow other vessels. This standard is applicable to small craft with a hull length up to 24 m. This International Standard does not define anchor weights or

39、4. Doubling plates or washers of adequate size shall be used where the strong points are secured with nuts and bolts. 7.2 Corrosion resistance Strong points shall be made of materials that are resistant to or protected against corrosion. Where non-metallic (plastics) strong points are provided, the

40、material shall be UV stabilized. In addition, a warning notice shall be listed in the owners manual to replace strong points showing visible signs of deterioration. 7.3 Labelling Where the intended use of a strong point for anchoring and/or being towed is not self evident, the strong point shall be

The breaking strength of lines/chains shall in general not exceed 80 % of the breaking stre

43、ngth of the respective strong point. A.2 Caution Where the purpose of a specific strong point is not self evident, the boat manufacturer shall label the strong point (strong point designated for anchoring and/or towing) and provide suitable information in the owners manual. A.3 Caution Always tow or

44、 be towed at a slow speed. Never exceed the hull speed of a displacement craft when being towed. A.4 Caution A tow line shall always be made fast in such a way that it can be released when under load. A.5 Responsibility It is the owners/operators responsibility to ensure that mooring lines, towing l

45、ines, anchor chain(s), anchor lines and anchor(s) are adequate for the vessels intended use, i.e. the lines or chains do not exceed 80 % of the breaking strength of the respective strong point. Owners should also consider what action will be necessary when securing a tow line on board. A.6 Non-metal

46、lic strong points Where non-metallic strong points are installed, their limited life time shall be taken into consideration. They shall be replaced once they show any signs of deterioration, visible surface cracks or permanent deformation. NOTE Black items are less prone to UV degradation than light
