This standard specifies the functional requirements and test methods for external organic coatings based on tapes or shrinkable materials ot 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 meed 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 loades caused by frequent temperature changes.Specifications of fillers are outside the scope of this European standard.
