本文件适用于内河航行船舶的舷外梯子。舷外梯子用于舷侧高度较大的内河航行船舶，以方便在登船高度明显不同的情况下安全登船、安全离船或安全越过船舶。本文件规定了舷外梯子的设计、尺寸、强度和试验条件的安全要求。舷外梯子适用于根据EN 1502的登船楼梯长度不够的范围。这一范围从大约在轻水线上方2.8 m处的登机高度开始。登机梯不供乘客使用。

This document applies to outboard ladders for inland navigation vessels. Outboard ladders are used on inland navigation vessels having great side heights to facilitate safe climbing into ship's boats, safe disembarking or safe crossing over onto vessels in the case of significantly different boarding heights. This document specifies safety requirements on design, dimensions and strength and test conditions for outboard ladders. Outboard ladders are intended for that range where boarding stairs according to EN 1502 are not sufficient in length. This range starts at a boarding height of approximately at 2,8 m above the light water-line. Boarding ladders are not intended for use by passengers.
