ISO 13643-6:2017定义了符号和术语，并提供了进行试验的指南，以确定水面船舶和潜艇模型在平面运动、圆周运动或倾斜拖曳或流动系统下由于规定运动而产生的水动力和力矩。它还定义了符号和术语，并为在风洞中进行试验提供了指南。本手册将与ISO 13643-1一起阅读。

ISO 13643-6:2017 defines symbols and terms and provides guidelines for the conduct of tests to determine the hydrodynamic forces and moments due to prescribed motions under a planar-motion, a circular-motion or an oblique towing or flow system for models of surface ships and submarines. It also defines symbols and terms and provides guidelines for the conduct of tests in a wind tunnel. It is intended to be read in conjunction with ISO 13643？1.
