Cathodic Disbondment Test for Coated Steel Structures Under Cathodic Protection
This test method describes an accelerated test procedure for determining comparative resistance to cathodic disbondment of protective coating systems applied to the exterior of steel pipes and structures that are buried in soil or submerged. This test method is intended for use with specimens of coated tube, a specimen cut from a section of coated pipe, or flat coated steel plates. This test method also is applicable to tank linings with an internal cathodic protection system. This test method is not intended for tape or sleeve coatings with a soft adhesive that may flow at the test temperature. This test method is intended to cover all service temperatures from ambient to elevated temperatures.
