26、er 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 organizations, government

27、al 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 ISO/IEC Direct

28、ives, 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 % of the member bodie

29、s 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 rights. ISO 12215-9 was prepared by Technical Committee ISO/TC 188, Small craft. ISO 12215

30、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: Materials: Steel, alum

31、inium 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 craft appendages BS EN IS

32、O 12215-9:2012ISO 12215-9:2012(E) ISO 2012 All rights reserved vIntroduction The reason underlying the preparation of 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

33、acceptability of craft. The loss of a keel leading to craft capsize is one of the major casualty hazards on sailing craft and therefore the structural efficiency of all elements of the keel and its connection to the craft is paramount. This part of ISO 12215 specifies the design loads and their asso

34、ciated stress factors. The user then has a choice between one or the other of the following available options for assessing the structural arrangement. a) Use of advanced engineering methods which allow the structure to be modelled as three-dimensional: suitable methods include finite element analys

35、is and subsets thereof such as matrix displacement or framework methods. General guidance is provided on modelling assumptions within this part of ISO 12215. b) Use of simplified, generally two-dimensional, “strength of materials”-based stress equations: These are presented in Annexes B to F and, if

36、 this option is chosen, use of the equations will be necessary to fulfil the requirements of this part of ISO 12215. This part of ISO 12215 has been developed applying present practice and sound engineering principles. The design loads and criteria of this part of ISO 12215 may be used with the scan

37、tling determination equations of this part of ISO 12215 or using equivalent engineering methods as indicated in a), above. The dimensioning according to this part of ISO 12215 is regarded as reflecting current practice, provided the craft is correctly handled in the sense of good seamanship and equi

38、pped and operated at a speed appropriate to the prevailing sea state. During the latter stages of the development of the ISO 12215 series, and after publication of key parts, a number of authorities adopted this International Standard for the assessment of high-performance racing yachts. While, in t

39、heory, a category A blue-water cruising yacht could experience the same loads as a competitive racing yacht, the latter has not been the principal focus of ISO 12215. Consequently, designers are strongly cautioned against attempting to design high-performance racing craft such that nearly all struct

40、ural components only just comply.

41、tlings of sailing craft appendages on monohull sailing craft with a length of hull, LH, of up to 24 m, measured according to ISO 8666.
