NACE TM0384-2002

This NACE standard test method was prepared as a guide for evaluating the application of polymeric coatings of less than 250 µm (10 mils) dry-film thickness to the internal surfaces of metallic tubular goods used in the oil and gas industry. This NACE standard provides a nondestructive method for the detection of holidays in a nonconductive coating film that has been applied to the inner wall of oilfield tubular goods. The apparatus and the recommended procedure for conducting the test are described, as are methods of reporting the test data. This standard is maintained by Task Group 449.
