Ductile iron pipes, fittings and accessories - External cement mortar coating for pipes - Requirements and test methods
Scope: This document specifies the requirements and test methods applicable to factory applied cement mortar coatings for the external corrosion protection of ductile iron pipes conforming to EN 545, EN 598 and EN 969 for use at operating temperatures up to 50 °C.
Coatings according to this document are suitable for soils of all common corrosion loads and trenchless applications.
Special activities on site such as joint protection, tapping, clamping, etc. could affect the corrosion protection properties of the cement mortar coating. These operations are normally covered in the laying instructions supplied by the manufacturers of pipes, clamps, house connection saddles, etc. and any relevant users' procedures. Such instructions are not part of this document.

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.
