Protection of metallic materials against corrosion - Guidance on the assessment of corrosion likelihood in water distribution and storage systems - Part 1: General

Asnjë informacion i shtuar.

This document gives guidance for the assessment of the corrosion likelihood of metallic materials in water distribution and storage systems, as a result of corrosion on the water-side. NOTE This document lists the different types of corrosion and describes in general terms the factors influencing corrosion likelihood. Water distribution and storage systems considered in this document are used for waters intended for human consumption according to EC directive 98/83/EEC and for waters of similar chemical composition. This document does not cover systems that convey the following types of water. - sea water; - brackish water; - geothermal water; - sewage water; - swimming pool water; - open cooling tower water; - recirculating heating and cooling water; - demineralized water. Parts 2 to 5 of this document cover the factors influencing the corrosion likelihood for copper and copper alloys, hot-dip galvanized ferrous materials, stainless steels and cast iron, unalloyed and low alloyed steels in detail. This document does not cover lead.
