DIN EN 13636:2004-10

This standard specifies the principles for the implementation of a system of cathodic protection against corrosive attacks on buried metal tanks and associated piping. This standard specifies conditions and parameters to be met in order to achieve cathodic protection, as well as rules and procedures for the design, installation, commissioning and maintenance for the protection of buried metal tanks and associated piping. This standard is applicable to the external surfaces of buried metallic tanks and associated buried piping. This standard is applicable to buried tanks and associated piping, even if they are earthed by their own local earthing device, which are electrically separated from any general earthing systems and other buried structures.
