Abstract

This document defines the requirements and gives recommendations for the chemical composition, the electrochemical properties, the physical tolerances, and the test and inspection procedures for cast galvanic anodes of aluminium, magnesium or zinc-based alloys for cathodic protection (CP) in seawater, saline sediment and brackish water. It is applicable to anodes in seawater but also applicable to anodes in brackish water and saline sediments. Information on salinity ranges can be found in Annex A. This document is applicable to the majority of galvanic anodes used for seawater, saline sediment and brackish water applications, i.e. cast anodes of trapezoidal, or circular cross section and bracelet type anodes. The requirements and recommendations of this document can also be applied to other anode shapes, e.g. half-spherical, button, etc., which are sometimes used for seawater applications.
