22、rds bodies (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 organ

23、izations, 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 i

24、n the ISO/IEC Directives, Part 2. 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 %

25、 of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

26、ll craft. ISO 12215 consists of the following parts, under the general title Small craft Hull construction and scantlings: Part 1: Materials: Thermosetting resins, glass-fibre reinforcement, reference laminate Part 2: Materials: Core materials for sandwich construction, embedded materials Part 3: Ma

27、terials: Steel, aluminium alloys, wood, other materials Part 4: Workshop and manufacturing Part 5: Design pressures for monohulls, design stresses, scantlings determination Part 6: Structural arrangements and details Part 7: Scantling determination of multihulls Part 8: Rudders Part 9: Sailing boats

28、 Appendages and rig attachments BS EN ISO 12215-6:2008vi Introduction The underlying reason for preparing this part of ISO 12215 is that standards and recommended practices for loads on the hull and the dimensioning of small craft differ considerably, thus limiting the general worldwide acceptabilit

29、y of boats. The objective of this part of ISO 12215 is to achieve an overall structural strength that ensures the watertight and weathertight integrity of the craft. This part of ISO 12215 is considered to have been developed with the application of current practice and sound engineering principles.

30、 Considering future development in technology and boat types, as well as small craft currently outside the scope of this part of ISO 12215, and provided that methods supported by appropriate technology exist, consideration may be given to their use so long as equivalent strength to this part of ISO

31、12215 is achieved. Dimensioning in accordance with this part of ISO 12215 is regarded as reflecting current practice, provided that the craft is correctly handled in the sense of good seamanship and that it is equipped and operated at a speed appropriate to the prevailing sea state. BS EN ISO 12215-

32、6:20081Small craft Hull construction and scantlings Part 6: Structural arrangements and details 1 Scope This part of ISO 12215 concerns structural details and structural components not explicitly included in ISO 12215-5, ISO 12215-7, ISO 12215-8 and ISO 12215-9. It applies to monohull and multihull

33、small craft constructed from fibre reinforced plastics (FRP), aluminium or steel alloys, wood or other suitable boat building material, with a hull length, in accordance with ISO 8666, of up to 24 m. This part of ISO 12215 fulfils two functions. Firstly, it supports ISO 12215-5 by providing further

34、explanations and calculation procedures and formulae. Secondly, it gives a number of examples of arrangements and structural details which illustrate principles of good practice. These principles provide a standard against which alternative arrangements and structural details can be benchmarked, usi

35、ng the equivalence criteria specified in this part of ISO 12215. NOTE Scantlings derived from this part of ISO 12215 are primarily intended to apply to recreational craft including recreational charter vessels and might not be suitable for performance racing craft. 2 Normative references The followi

36、ng referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.

39、tions apply. 3.1 loaded displacement mass mLDCmass of the craft, including all appendages, when in the fully-loaded ready-for-use condition, as defined in ISO 8666 BS EN ISO 12215-6:20082 3.2 sailing craft craft for which the primary means of propulsion is by wind power, and for which AS 0,07(mLDC)2

40、/3where ASis the total profile area of all sails that can be set at one time when sailing closed hauled, as defined in ISO 8666, expressed in m2; mLDCis the loaded displacement, as defined in ISO 8666, expressed in kg. NOTE In this part of ISO 12215, non-sailing craft are referred to as motor craft.

41、 3.3 grid grillage set of transverse stiffeners that intersect a set of longitudinal stiffeners 3.4 secondary stiffener stiffening element that directly supports the plating NOTE In a stiffener grillage, secondary stiffeners usually correspond to stiffeners having the lower second moment of area, e.

42、g. stringers, frames, partial bulkheads. The spacing of secondary stiffeners generally corresponds to the shortest unsupported span of the attached plating. In the case of stiffeners with a substantial base width (i.e. top hat stiffeners), the stiffener spacing will be the unsupported panel span plu

43、s this base width. 3.5 primary stiffener stiffening element that supports the secondary stiffening element NOTE 1 In a stiffener grillage, primary stiffeners usually correspond to stiffeners which have the higher second moment of area, e.g. structural bulkheads, girders, web frames. The spacing of p

44、rimary stiffeners generally corresponds to the span of secondary stiffeners. NOTE 2 Some stiffeners, such as bulkheads, deep girders or web frames, may also contribute to resisting global loads. 3.6 stringer longitudinal stiffener, generally designated a secondary stiffener (3.4), which supports the

45、 shell plating 3.7 frame transverse stiffener, generally designated a secondary stiffener (3.4), which supports the shell plating 3.8 beam transverse stiffener, generally designated a secondary stiffener (3.4), which supports the deck plating 3.9 web frame substantial transverse stiffener, generally

46、 designated a primary stiffener (3.5), which supports stringers and less substantial girders and is usually connected with substantial deck beams NOTE The spacing of web frames is usually greater than (or some multiple of) the frame or beam spacing. 3.10 floor substantial transverse bottom stiffener

47、, which may be used to link frames and may also be a partial bulkhead NOTE Floors are often used to support a cabin sole, so the upper edge is generally horizontal. On sailing craft, floors are traditionally used to support ballast keels. BS EN ISO 12215-6:200833.11 girder substantial longitudinal s

48、tiffening element, generally designated a primary member, which supports bottom transverse frames or floors, other frames and beams NOTE Bottom girders are sometimes called keelsons. 3.12 bracket stiffening element, usually of triangular shape, used to reinforce the connection of two stiffeners and

49、to reduce their span NOTE Brackets are also used to transmit local loads. 4 Symbols Unless specifically otherwise defined, the symbols and units used in this part of ISO 12215 are given in Table 1.
