26、on 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 a subject for which a technical committee has been established ha
27、s 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 Commission (IEC) on all matters of electrotechnical standardization. Inte
28、rnational Standards are drafted in accordance with the rules given in 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. Publica
29、tion 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 document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rig

33、uction or networking permitted without license from IHS -,-,- vi 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 acce
34、ptability 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 pri
35、nciples. 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
36、 of ISO 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.

38、 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 small craft constructed from fibre reinforced plast
39、ics (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 explanations and calculation procedures and formula
40、e. 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, using the equivalence criteria specified in this part
41、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 following referenced documents are indispensable for the a

47、defined in ISO 8666, expressed in m2; mLDC is 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. 3.3 grid grillage set of transverse stiffeners that intersect a set of longitudinal stiffeners 3.4 seconda
48、ry 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.g. stringers, frames, partial bulkheads. The spacing of secondary stiffeners generally corresponds to the shortest unsupported span of the attached plating. In the
