The ASTM D6676-21 standard introduces a test method for evaluating the cathode disbonding performance of pipe wall coatings under heating conditions. The method measures the disbonding behavior of coatings at temperature layers by simulating the actual temperature conditions of pipes in heating media. The test includes physical inspection and monitoring of current consumption to evaluate the disbonding resistance of coatings at high temperatures. This test provides standardized data support for studying and comparing the performance of different coatings in actual use environments.
