Scope

This standard specifies an accelerated test method for evaluating the high-temperature cathodic stripping performance of pipeline external anticorrosive coatings. This standard is applicable to the comparative testing of the high-temperature cathodic stripping performance of insulating external anticorrosive coatings for buried pipelines with cathodic protection and operating temperatures above normal temperature. This standard provides a test method for the cathodic stripping performance of anticorrosive coatings immersed or fully soaked in high-temperature solutions. If the specimens require testing at room temperature, SY/T 0037 can be used. If the specimens cannot be immersed or soaked, SY/T 0094 can be used.
