Annex L (informative) Saponification value
Annex M (normative) Microbiological resistance
Annex N (normative) Low temperature flexibility
Annex P (normative) Low temperature unrolling test
Annex Q (normative) Drip resistance of petrolatum tapes

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.
