小艇.稳定性和浮力评估和分类.第3部分:船体长度小于6m的船

[中文适用范围]： 本文件规定了评估完整（即未损坏）船只的稳定性和浮力的方法。 还包括易受沼泽影响的船只的漂浮特性。 使用本文件对稳定性和浮力特性进行评估将使船舶能够被分配到适合其设计和最大负载的设计类别（C 或 D）。 本文件适用于船体长度小于 6 m 的船舶，无论是人力还是机械动力推进，但可居住的航行多体船除外。 船体长度小于 6 m 且配备符合 ISO 11812 标准的全甲板和快速排水驾驶舱的船舶也可以使用 ISO 12217-1 或 ISO 12217-2 进行评估（对于非帆船和帆船，分别），在这种情况下可以分配更高的设计类别。 对于可居住的多体船，本文件包括对倒转敏感性的评估、可行逃生手段的定义以及倒转漂浮的要求。 本文件不包括： ——ISO 6185 系列涵盖的充气船和刚性充气船，但参考文献除外 — ISO 13590 涵盖的个人船只和其他类似动力艇； ——水上玩具； ——独木舟和皮划艇； ——贡多拉和脚踏船； ——帆船冲浪板； ——冲浪板，包括动力冲浪板； ——不以排水模式运行时的水翼艇、水翼稳定艇和气垫船；和——潜水器。 注：位移模式意味着船仅由静水力支撑。 它不包括或评估拖曳、捕鱼、疏浚或起重作业对稳定性的影响，如果合适，需要单独考虑。 1 [外文原描述]： This document specifies methods for evaluating the stability and buoyancy of intact (i.e. undamaged) boats. The flotation characteristics of craft susceptible to swamping are also encompassed. The evaluation of stability and buoyancy properties using this document will enable the boat to be assigned to a design category (C or D) appropriate to its design and maximum load. This document is applicable to boats of hull length less than 6 m, whether propelled by human or mechanical power, except habitable sailing multihulls. Boats of hull length less than 6 m which are fitted with a full deck and quick-draining cockpit(s) complying with ISO 11812 can alternatively be assessed using ISO 12217 ‑ 1 or ISO 12217 ‑ 2 (for non-sailing and sailing boats, respectively), in which case higher design categories can be assigned. In relation to habitable multihulls, this document includes assessment of susceptibility to inversion, definition of viable means of escape and requirements for inverted flotation. This document excludes: — inflatable and rigid-inflatable boats covered by the ISO 6185 series , except for references made in the ISO 6185 series to specific clauses of the ISO 12217 series ; — personal watercraft covered by ISO 13590 and other similar powered craft; — aquatic toys; — canoes and kayaks; — gondolas and pedalos; — sailing surfboards; — surfboards, including powered surfboards; — hydrofoils, foil stabilized boats and hovercraft when not operating in the displacement mode; and — submersibles. NOTE Displacement mode means that the boat is only supported by hydrostatic forces. It does not include or evaluate the effects on stability of towing, fishing, dredging or lifting operations, which need to be separately considered if appropriate.
