DIN EN 13509:2003-09

This Standard deals with the cathodic protection against corrosion of buried or immersed metallic structures, detailing the measuring methods to be used for assessing the effectiveness of cathodic protection as well as the measurements and measures taken to monitor cathodic protection during operation. Throughout the text, the measurement techniques are described primarily for pipelines. However, they are sufficiently general to apply to all other kinds of buried or immersed structures.
