Anticorrosion protection of underground structures by electric drainage as per European standards

WOJCIECH SOKÓLSKI

After accessing the European Union almost all standards elaborated in Poland expired and had been successively replaced by documents elaborated by the European Committee for Standardisation. In the article it has been pointed out - on the example of anticorrosion protection of underground steel structures from stray currents - that with this change also a new "western" approach philosophy to solving problems is sometimes being promoted, different to that established in previous years in the Polish technical environment. In accordance with this philosophy electric drainage is not one of the forms of acquiring electric energy for cathodic protection, but only a tool for eliminating harmful interference caused by stray currents in underground structures. Keywords: risk of corrosion, stray currents, interference, electric drainage, standards.Introduction In the nineties, when it was known that Poland would become a member of the European Union, the cathodic protection technology environment closed its own standardisation activities, awaiting for technical requirement standardisation at the international level. Cooperation between the Polish Committee for Standardisation (PKN) and the European Committee for Standardization (CEN) started already before the year 2000. Initially Poland did not directly participate in CEN works, acting as observer only, this leading to access to newly elaborated documents for the Polish technical environment. After accessing the European Union all standards elaborated in Poland expired and had been successively replaced by documents elaborated by the European Committee for Standardisation. The technical committee dealing with cathodic protection problems in the European Committee for Standardisation CEN - TC 219 "Cathodic protection" was founded in 1990 with the secretariat at the British Standard Institute. The following were included in activities of the Committee: standardisation of cathodi[...]
