16、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 has the right to be represented on that committee. I
17、nternational 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. International Standards are drafted in accordance with
18、 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 committees are circulated to the member bodies for voting. Publication as an International Standard requires approva
19、l 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 12215 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 12215-3 was prepared by Technica
20、l Committee ISO/TC 188, Small 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, em

23、This part of ISO 12215 specifies requirements for materials intended for use in the construction of the hull, superstructure and appendages, in particular: weldable normal and higher strength hot-rolled steel plates, wide flats, sections and bars; austenitic stainless steels, fabricated in the form
24、of plates or profiles; wrought aluminium alloys fabricated as plates, sections and extruded profiles; wood in the form of solid timber, plywood or veneer; other suitable materials. NOTE 1 Other materials may be used in the construction of small craft if adequate suitability and durability for the in
25、tended purpose can be demonstrated. This part of ISO 12215 applies to small craft with a length hull (L H ) according to ISO 8666 of up to 24 m. NOTE 2 The underlying reason for preparing this part of ISO 12215 is that the choice of materials for the construction of a small craft has a significant i
26、nfluence on short-term and long-term durability under the expected loads and environmental conditions. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of ISO 12215. For dated references, subsequent
27、amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part of ISO 12215 are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edi
28、tion of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards.

29、s For the purposes of this part of ISO 12215, the following terms and definitions apply. 1) To be published. SANS 12215-3:2008This standard may only be used and printed by approved subscription and freemailing clients of the SABS.ISO 12215-3:2002(E) 2 ISO 2002 All rights reserved 3.1 durability natu
30、rally inherent property of a wood species to indicate the service time of the heartwood used in the open air without any preservation NOTE The designation of durability of wood is given in Table 1. 3.2 veneer solid wood with a thickness of no more than 5 mm in its finished state 4 Requirements for m
31、etal 4.1 Properties of materials Materials covered by this part of ISO 12215 are dealt with by many international and national standards, also classification societies, active in the survey of ships and small craft. The properties of all metal used in the construction of small craft shall be suitabl
32、e for marine use and the intended methods of construction. The metal shall comply with a relevant International or National Standard, classification society rule or be supported by documentation to validate its suitability for marine use. 4.2 Selection of materials The choice of materials shall take
33、 into account the manufacturing conditions in the boat yard, environmental limitations, the anticipated manufacturing process, the competence of welders and the welding equipment being used, as specified in ISO 12215-4. 4.3 Material combinations 4.3.1 When combining metals of different type or compo
34、sition, the galvanic potential difference must be considered in order to avoid contact corrosion. NOTE The rate of contact corrosion may be influenced by environmental conditions, heat treatment, welding and forming. 4.3.2 The negative effect on certain timber by adjacent metals and vice versa shall
35、 be taken into account when selecting the materials to be in contact or shall be neutralized, e.g. by shielding or insulation. NOTE These may be wood species containing chemical substances, or composites using electrically conductive material, e.g. carbon fibre. 4.4 Freedom from defects The metal us
36、ed shall have a suitable finish for the intended application and shall be free from surface defects prejudicial to use for the intended application. 4.5 Identification of materials The manufacturer or supplier of the material shall adopt a system of identification, e.g. by colour coding or stamping,
37、 that will enable the material to be traced to its original manufacture. 4.6 Steel 4.6.1 General Steel used for the construction of small craft shall be normal strength steel (mild steel) in accordance with 4.6.2 or higher strength steel in accordance with 4.6.3. SANS 12215-3:2008This standard may o
38、nly be used and printed by approved subscription and freemailing clients of the SABS.ISO 12215-3:2002(E) ISO 2002 All rights reserved 34.6.2 Normal strength steel The minimum mechanical properties of normal strength steel shall be yield strength: R eH= 235 N/mm 2 , and tensile strength: R m= 340 N/m
39、m 2 . Mild steels should be the preferred choice for the construction of small craft, because of their ductility, ease of welding and reduced likelihood regarding possible loss of mechanical properties by welding. 4.6.3 Higher strength steel Higher strength steel may be used in the construction of s
40、mall craft provided it is taken into consideration that, when fatigue load is present, the effective fatigue strength of a welded joint may not be greater than a welded joint in normal strength steels. Before subjecting steels produced by thermo-mechanical rolling to further heating for forming or s
41、tress relieving, or using high heat-input welding, account shall be taken of the possibility of a subsequent reduction in mechanical properties. The mechanical properties of higher strength steels shall be yield strength: R eH= 315 N/mm 2to 390 N/mm 2 , and tensile strength: R m= 440/570 N/mm 2to 51
42、0/660 N/mm 2 . 4.6.4 Austenitic stainless steels may be used for construction in small craft subject to giving consideration to the environmental conditions to which the small craft may be subjected, any intended combination of different metals, the means of insulation from each other and surface pr
43、otection or coating, and the detail design to reduce the possibility of pitting and/or crevice corrosion. NOTE This group of steels comprises low-carbon austenitic steels which achieve their resistance to corrosion in fresh and sea water by additions of chromium (Cr), nickel (Ni), molybdenum (Mo), a
44、nd may additionally be stabilized for a stable after- welding condition by titanium (Ti) and niobium (Nb). Alloys suitable for marine use are in general those with a minimum mass fraction of 12 % chromium and a pitting resistance equivalent (W) exceeding 25 (W = % Cr + 3,3 % Mo). 4.7 Aluminium alloy
45、s 4.7.1 General The following types of aluminium alloys may be used for construction in small craft: non-heat-treatable alloys; heat-treatable alloys. Both groups comprise types of alloys that are resistant to sea water. Both groups are delivered in different temper conditions, having a significant
46、effect on the mechanical properties. It should be recognized that the mechanical properties of treated alloys may be reduced after welding.

47、ts reserved 4.7.2 Non-heat-treatable aluminium alloys The major alloy component for this material group, regarded as sea water resistant, is magnesium (Mg). Additionally manganese (Mn) or silicon (Si) may be contained. NOTE Typical applications for these alloys are rolled products, e.g. sheets, stri
48、ps and plates. 4.7.3 Heat-treatable aluminium alloys The major alloy component for this material group, regarded as sea water resistant, is silicon (Si). Additionally magnesium (Mg) and/or manganese (Mn) may be contained. NOTE Typical applications for these alloys are extruded products, e.g. section
49、s, shapes, bars and closed profiles. 4.7.4 Other aluminium alloys Alloys of the aluminium-copper group and the aluminium-zinc group should not be used for the construction of small craft. They may be used for secondary purposes in small craft with special protection, e.g. anodizing, painting. Aluminium-copper alloys may be used without protection for small boats that are intended to be used exclusively in fresh water surroundings. It is preferable that they are not of welded construc
