英文名称：Small craft — Hull construction and scantlings — Part 5: Design pressures for monohulls, design stresses, scantlings determination
发布日期：2008-04
标准范围
This part of ISO 12215 applies to the determination of design pressures and stresses, and to thedetermination of the scantlings, including internal structural members of monohull small craft constructed fromfibre-reinforced plastics, aluminium or steel alloys, glued wood or other suitable boat building material, with alength of hull, LH, in accordance with ISO 8666, between 2,5 m and 24 m. It only applies to boats in the intactcondition.It only applies to craft with a maximum speed u 50 knots in mLDC conditions.The assessment shall generally include all parts of the craft that are assumed watertight or weathertight whenassessing stability, freeboard and buoyancy in accordance with ISO 12217 and are essential to the safety ofthe craft and of persons on board.For the complete scantlings of the craft, this part of ISO 12215 is used in conjunction with Part 6, for details,Part 7 for multihulls, Part 8 for rudders and Part 9 for appendages and rig attachment.The scantling determination of windows, portlights, deadlights, hatches and doors, is in accordance withISO 12216. The structure supporting these elements is in accordance with this part of ISO 12215.NOTE 1 Scantlings derived from this part of ISO 12215 are primarily intended to apply to recreational craft includingrecreational charter vessels and may not be suitable for performance racing craft.NOTE 2 This part of ISO 12215 is based on the assumption that scantlings are governed solely by local loads.NOTE 3 The scantling requirements of this part of ISO 12215 are considered to correspond to the minimum strengthrequirements of motor and sailing craft which are operated in a safe and responsible manner, having due cognisance ofthe prevailing conditions.Pressures and stresses are normally expressed in pascals, kilopascals or megapascals. For the purposes of abetter understanding for the users of this part of ISO 12215, the pressures are expressed in kilonewtons persquare metre (1kN/m2 = 1kPa) and stresses or elastic moduli are expressed in newtons per square millimetre(1 N/mm2 = 1 MPa).
