This document specifies the requirements and recommendations for cathodic protection systems applied to the internal surfaces of metallic tanks, structures, equipment, and piping containing raw or treated seawater or brackish waters, to provide an efficient protection from corrosion.

Cathodic protection inside fresh water systems is excluded from this document. This is covered by EN 12499.

NOTE EN 12499 covers internal cathodic protection for any kind of waters, including general aspects for seawater; but excluding industrial cooling water systems. This document specifically details applications in seawater and brackish waters.

This document describes methods of scribing coated steel or test-pieces for corrosion tests, where the coating system is applied at dry film thicknesses of less than 500 μm. It is intended as a guideline only, being based on the results of a collaborative trial with no subsequent corrosion testing having been carried out to determine the suitability of the introduced scribe marks for such tests.

This document covers the scribing of metallic panels or test pieces (chemically treated or not) made from:

— steel,

— galvanized steel,

— aluminium alloys,

— magnesium alloys.

It does not cover the scribing of electroplated metal or clad aluminium panels.
