标准范围

本文件定义了船体长度（LH）或载重线长度不超过24 m的多壳船的尺寸、局部设计压力和整体载荷（见注释）。在根据ISO 12217（所有部件）评估稳定性、干舷和浮力时，它考虑了假定水密或防风雨的船舶所有部件。然后使用ISO 12215-5评估对应于局部设计压力的尺寸。注:载重线长度在OMI“1966/2005国际载重线公约”中定义，对于有悬垂的船舶，载重线长度可以小于LH。该长度也设定为24 m，是几项IMO公约的下限。本文件适用于由与ISO 12215-5相同的材料建造、完好无损且具有以下两种类型的多壳船:-游乐船只，包括游乐租船；-商业船只和工作船。它不适用于仅为职业比赛设计的多体赛车。本文件适用于支撑窗户、舷窗、舱口、死灯和门的结构。对于船舶的完整尺寸，本文件旨在与ISO 12215-8（舵）、ISO 12215-9（帆船附件）和ISO 12215-10（帆船中的钻机负载和钻机附件）一起使用。ISO 12215-6可用于其他细节。在整个文件中，除非另有说明，尺寸以（m）为单位，面积以（m2）为单位，质量以（kg）为单位，力以（N）为单位，力矩以（Nm）为单位，压力以（kN/m2）为单位（1kN/m2=1kPa），应力和弹性模量以（N/mm2）为单位（1N/mm2=1MPa）。

This document defines the dimensions, local design pressures and global loads acting on multihull craft with a hull length (L_H) or load line length of up to 24 m (see Note). It considers all parts of the craft that are assumed watertight or weathertight when assessing stability, freeboard and buoyancy in accordance with ISO 12217 (all parts). Scantlings corresponding to the local design pressures are then assessed using ISO 12215-5.NOTE The load line length is defined in the OMI "International Load Lines Convention 1966/2005", it can be smaller than L_H for craft with overhangs. This length also sets up at 24 m the lower limit of several IMO conventions.This document is applicable to multihulls built from the same materials as in ISO 12215-5, in intact condition, and of the two following types:— recreational craft, including recreational charter vessels;— commercial craft and workboats.It is not applicable to multihull racing craft designed only for professional racing.This document is applicable to the structures supporting windows, portlights, hatches, deadlights and doors.For the complete scantlings of the craft, this document is intended to be used in conjunction with ISO 12215-8 for rudders, ISO 12215-9 for appendages of sailing craft and ISO 12215-10 for rig loads and rig attachment in sailing craft. ISO 12215-6 can be used for additional details.Throughout this document, unless otherwise specified, dimensions are in (m), areas in (m²), masses in (kg), forces in (N), moments in (Nm), Pressures in (kN/m²) (1 kN/m² = 1 kPa), stresses and elastic modulus in (N/mm²) (1 N/mm² = 1 MPa).
