Plastics hoses — Helical-thermoplastic-reinforced thermoplastics hoses for suction and discharge of aqueous materials — Specification
Scope: This document specifies requirements for three types of helical-thermoplastic-reinforced thermoplastics hoses for suction and discharge of water, weak aqueous chemical solutions and abrasive solids and slurries, for use in the ambient temperature range from −10 °C to 55 °C.
This document does not specify requirements for use with flammable or combustible materials, nor with aromatic solvents.

Rubber hoses and hose assemblies, wire or textile reinforced, for dredging applications — Specification
Scope: 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.
