14、SO 2002 All rights reserved 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 intereste
15、d 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 Electrotechnical Com
16、mission (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 techni
17、cal 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 right
18、s. ISO 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 cat

24、ce 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 boats vulnerable to swamping
25、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 (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 huma
26、n or mechanical power of 6 m up to and including 24 m hull length. However, it may also be applied to 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
27、 excludes inflatable and rigid-inflatable boats up to 8 m covered by ISO 6185, canoes, kayaks or other 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 towin
28、g, fishing, dredging or lifting operations, which should be separately considered if appropriate. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of ISO 12217. For dated references, subsequent amend
29、ments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part of ISO 12217 are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below.

The angle of heel at which downflooding opening(s) described in 6.1.1.1 having a total combined area, expressed in square millimetres, greater than the number represented by 50LH2 first become immersed, shall be greater than the requirements given in Ta

Where a downflooding opening is prote
38、cted by a higher coaming around the recess from which it leads, the downflooding angle shall be determined to the lowest point of that coaming, see Figure C.1 in annex C. The downflooding angle (fD) may be determined using either of the methods in annex C. 6.2 Offset-load test This test is to demons
39、trate sufficient stability for the boat at loaded displacement mass against offset loading by the crew. Conduct the offset-load test in accordance with annex B using either physical test or calculation methods, thus obtaining the offset-load heel angle fO. For all design categories, the heel angle f

44、sses of boats to be assigned design category A or B using option 1 of Table 2 shall comply with the plan area limitations given below, unless specific account is taken of the mass and free-surface effect of water that recesses may contain when calculating the stability characteristics. If this speci
45、al calculation option is used, righting moments shall be calculated assuming that each recess is treated as though it had no drainage and is assumed to initially hold water to the following percentage of its maximum (upright) capacity: Percentage full = 60 - 240F/LH where F is the minimum freeboard
46、to the coaming of the recess in question. Such water shall be assumed to spill out as the boat heels, the righting moments being assumed to be symmetrical about the upright. For design category A: plan area of all recesses (m2) 1,15, in which case the loaded displacement condition shall also be asse
47、ssed. Boats of design categories C and D, where ALV where ()m h, is the sum for all variations from the standard outfit of the product of the mass of the component and its height above the waterline. B.4 Application of MC by a physical test Test weights or persons may be used to represent the mass o
48、f the crew. Where persons are used, their average mass shall be W 75 kg. If standing, they should stand with feet together and maintain their balance without using handholds. When the position for the test weights or persons that result in the heeling moment MC required by clause B.3 has been found, the heel angle shall be measured. The test shall then be repeated with the boat heeling in the other direction. The
