Defines the functional requirements and test procedures for external organic coatings based on tapes or shrinkable materials for use for corrosion protection of buried and immersed steel pipelines in conjunction with cathodic protection. Does not apply to special applications in off-shore and stress loads brought about by frequent changes of temperature, nor to specifications of filters.

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. Tapes and shrinkable materials which meet the requirements of these classes can belong to various types defined in this standard.
This European Standard is not applicable to special applications in off-shore and stress loads caused by frequent temperature changes.
Specifications of fillers are outside the scope of this European Standard.
