This European Standard is applicable to pipelines with a maximum operating pressure (MOP) over 16 bar for the carriage of processed, non-toxic and non-corrosive natural gas according to EN ISO 13686 in onland gas infrastructure. This European Standard is also applicable to pipelines with a maximum operating pressure (MOP) over 16 bar for the carriage of non-conventional gases such as injected biomethane, complying with EN ISO 13686 and for which a detailed technical evaluation of the functional ...view more

This European 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 other kinds of buried or immersed (except off...

This standard specifies the functional requirements and test methods for external organic coatings based on tapes or shrinkable materials to be used for corrosion protection of buried and immersed steel pipelines in conjunction with cathodic protection. It classifies coatings by increasing mechanical resistance and operating temperatures. Coatings for special installation conditions are also considered. A comprehensive classification of coatings in relation to functional requirements is defined.

ISO 18086:2015 is applicable to buried cathodically-protected pipeline that is influenced by AC traction systems and/or AC power lines.
In the presence of AC interference, the protection criteria given in ISO 15589 1 are not sufficient to demonstrate that the steel is being protected against corrosion.
ISO 18086:2015 provides limits, measurement procedures, mitigation measures, and information to deal with long term AC interference for AC voltages at frequencies between 16,7 and 60 Hz and the ...
