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 1300. 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: type1: floating type, for delivery only, which includes flotation material to give the hose buoyancy; type2: submarine type for delivery and suction.
