标准范围

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。使用本文件评估稳定性和浮力特性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米的船只，不论是由人力或机械动力推进，但可居住的多体帆船除外。船体长度小于6米、配备符合ISO 11812标准的全甲板和快速排水驾驶舱的船只也可以使用ISO？12217？1还是ISO？12217？2（分别用于非帆船和帆船），在这种情况下，可以分配更高的设计类别。关于可居住多体船，本文件包括对倾覆敏感性的评估、可行逃生方式的定义以及倒置漂浮的要求。本文件不包括:—？ISO涵盖的充气和刚性充气船？6185？系列，除了ISO中的引用？6185？ISO特定条款系列？12217？系列；—？ISO涵盖的个人船只？13590和其他类似动力飞行器；—？水上玩具；—？独木舟和皮艇；—？平底船和脚踏船；—？帆船冲浪板；—？冲浪板，包括动力冲浪板；—？不在排水量模式下操作时的水翼、翼稳定艇和气垫船；和—？潜水器。笔记？位移模式意味着船仅由静水力支撑。它不包括或评估对拖曳、捕鱼、疏浚或起重作业稳定性的影响，这些需要在适当情况下单独考虑。

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.
