What is BS EN 12954 – Cathodic protection of buried or immersed onshore metallic structures about?
BS EN 12954 is a European standard that discusses the general principles of cathodic protection of buried or immersed onshore metallic structures.
BS EN 12954 describes the general principles for the implementation and management of a system of cathodic protection against corrosive attacks on structures that are buried or in contact with soils, surface freshwaters or underground waters, with and without the interference of external electrical sources.
BS EN 12954 specifies the protection criteria to be achieved to demonstrate the cathodic protection effectiveness.
Who is BS EN 12954 – Cathodic protection of buried or immersed onshore metallic structures for?
BS EN 12954 on cathodic protection of buried or immersed onshore metallic structures is applicable to:
- Manufacturers of onshore metallic structures
- Offshore drilling companies
- Operators of buried or immersed onshore metallic structures
- Engineers and designers of buried or immersed onshore metallic structures
Why should you use BS EN 12954 – Cathodic protection of buried or immersed onshore metallic structures?
A cathodic protection system is an all active and passive component associated with the provisions of active external corrosion protection and its monitoring.
BS EN 12954 gives you guidance on cathodic protection which is a technique based on the application of electrochemical principles. It is achieved by the supply of sufficient direct current to the external surface, such that the metallic structure to electrolyte potential is shifted to more negative values where external corrosion becomes insignificant. Cathodic protection also covers a wide range of materials and equipment and requires a variety of measurement techniques.
BS EN 12954 specifies conditions that are necessary to consider cathodic protection as an efficient method that can be applied to mitigate corrosion.
BS EN 12954 helps you prevent corrosion on buried or immersed onshore metallic structures.
What’s changed since the last update?
