标准范围

ISO 12473涵盖了应用于海水、微咸水和海泥时阴极保护的一般原则。它旨在作为一个介绍，提供理论方面和实际应用之间的联系，并构成对致力于海水中钢结构阴极保护的其他标准的支持。ISO 12473规定了阴极保护所需的标准。它提供了关于参比电极、设计考虑和防止阴极保护的二次效应的建议和信息。以下标准涵盖了海水中阴极保护的实际应用:-EN 12495，固定钢海上结构的阴极保护；-ISO 13174，港口设施的阴极保护(ISO 13174)；-EN 12496，用于海水和含盐泥浆中阴极保护的电偶阳极；-EN 13173，钢制海上浮动结构的阴极保护；-EN 16222，船体的阴极保护；-EN 12474，海底管道的阴极保护；-ISO 15589？2、石油石化和天然气行业？管道运输系统的阴极保护？第2部分:海上管道。对于暴露于海水或大气中的钢筋混凝土的阴极保护，ISO 12696适用。

ISO 12473 covers the general principles of cathodic protection when applied in seawater, brackish waters and marine mud. It is intended to be an introduction, to provide a link between the theoretical aspects and the practical applications, and to constitute a support to the other standards devoted to cathodic protection of steel structures in seawater.ISO 12473 specifies the criteria required for cathodic protection. It provides recommendations and information on reference electrodes, design considerations and prevention of the secondary effects of cathodic protection.The practical applications of cathodic protection in seawater are covered by the following standards:- EN 12495, Cathodic protection for fixed steel offshore structures;- ISO 13174, Cathodic protection of harbour installations (ISO 13174);- EN 12496, Galvanic anodes for cathodic protection in seawater and saline mud;- EN 13173, Cathodic protection for steel offshore floating structures;- EN 16222, Cathodic protection of ship hulls;- EN 12474, Cathodic protection of submarine pipelines;- ISO 15589？2, Petroleum, petrochemical and natural gas industries?Cathodic protection of pipeline transportation systems?Part 2: Offshore pipelines.For cathodic protection of steel reinforced concrete whether exposed to seawater or to the atmosphere, ISO 12696 applies.
