19、2002 All rights reservedForeword 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 interested in

20、 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 Electrotechnical Commiss

21、ion (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical

22、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 drawn to the possibility that some of the elements of this part of ISO 12217 may be the subject of patent rights. I

23、SO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 12217-1 was prepared by Technical Committee ISO/TC 188, Small craft. ISO 12217 consists of the following parts, under the general title Small craft Stability and buoyancy assessment and categor

24、ization: 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 hull length less than 6 m Annexes A, B, C, D, E, F and G form a normative part of this part of ISO 12217.

28、r 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 boats vulnerable to swamping are also encompassed. The evaluation of stability and buoyancy properties using this part of ISO 12217

29、 will enable the boat to be assigned to a design category (A, B, C or D) appropriate to its design and maximum total load. This part of ISO 12217 is principally applicable to boats propelled by human or mechanical power of 6 m up to and including 24 m hull length. However, it may also be applied to

30、boats of under 6 m if they do not attain the desired design category specified in ISO 12217-3 and they are decked and have quick-draining recesses which comply with ISO 11812. This part of ISO 12217 excludes inflatable and rigid-inflatable boats up to 8 m covered by ISO 6185, canoes, kayaks or other

31、 boats with a beam of less than 1,1 m, 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 No
