19、dies (ISO member 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 organizatio

20、ns, governmental 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. International Standards are drafted in accordance with the rules given in the

21、ISO/IEC Directives, Part 3. The main task of technical 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 th

22、e member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this part of ISO 12217 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 12217-3 was prepared by Technical Committee ISO/TC 188,

23、Small craft. ISO 12217 consists of the following parts, under the general title Small craft Stability and buoyancy assessment and categorization: Part 1: Non-sailing boats of hull length greater than or equal to 6 m Part 2: Sailing boats of hull length greater than or equal to 6 m Part 3: Boats of h

27、 m CAUTION Compliance with this part of ISO 12217 does not guarantee total safety or total freedom of risk from capsize or sinking. 1 Scope This part of ISO 12217 specifies methods for evaluating the stability and buoyancy of intact (i.e. undamaged) boats. The flotation characteristics of craft vuln

28、erable to swamping are also encompassed. The evaluation of stability and buoyancy properties using this part of ISO 12217 will enable the boat to be assigned to a design category (C or D) appropriate to its design and maximum load. This part of ISO 12217 is applicable to boats of hull length less th

29、an 6 m, whether propelled by human or mechanical power, except habitable sailing multihulls. Boats of hull length less than 6 m, which are fitted with a full deck and quick-draining cockpit(s) complying with ISO 11812, may alternatively be assessed using ISO 12217-1 or ISO 12217-2 (for non-sailing a

30、nd sailing boats respectively), in which case higher design categories may be assigned. This part of ISO 12217 excludes aquatic toys, canoes, kayaks or other boats with a beam of less than 1,1 m, inflatable and rigid-inflatable boats up to 8 m covered by ISO 6185, personal watercraft covered by ISO

31、13590, hydrofoils and hovercraft when operating in the dynamically supported mode, and submersibles. It does not include or evaluate the effects on stability of towing, fishing, dredging or lifting operations, which should be separately considered if appropriate. 2 Normative references The following

32、 normative documents contain provisions which, through reference in this text, constitute provisions of this part of ISO 12217. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part of ISO 12217 are
