标准摘要
[中文适用范围]： 本文档规定了两种类型、七个类别和三个等级的钢丝或纺织材料增强的疏浚软管的技术要求，其公称尺寸范围为100至1300毫米。此类软管适用于在环境温度-10°C至+40°C条件下，输送或抽吸海水或淡水与淤泥、砂、珊瑚及小石块的混合物（混合物比重为1.0至2.3）；低温型软管（标记为-LT）的使用温度范围为-20°C至+40°C。本文档涵盖的两种软管类型如下： 类型1：浮式型，仅用于输送，软管内含有浮力材料以确保其漂浮； 类型2：水下型，适用于输送和抽吸作业。 [外文原描述]： This document specifies requirements for two types, seven classes and three grades of wire- or textile-reinforced dredging hoses with nominal sizes ranging from 100 to 1 300. Such hoses are suitable for the delivery or suction of seawater or freshwater mixed with silt, sand, coral and small stones with a specific gravity in the range from 1,0 to 2,3 at ambient temperature ranging from -10 °C to +40 °C or for low-temperature hoses (designated -LT) ranging from -20 °C to +40 °C. This document covers two types of hose, as follows: type 1: floating type, for delivery only, which includes flotation material to give the hose buoyancy; type 2: submarine type for delivery and suction.
