Test method for the detection of holidays in a nonconductive coating film (of 10 mil [0.25 mm] thickness or less) that has been applied to the inner wall of oil field tubular goods. Apparatus. Procedures. Reporting methods. Historical Document 1989
This NACE standard practice provides a test method for the detection of holidays in a nonconductive coating film that has been applied to the inner wall of oil field tubular goods. The apparatus to and the recommended procedures for conducting the test are described here. Methods of reporting the test date are also described.
The test method applies to coatings that have a dry thickness of less than 10 mils (0.25).
This test method gives the best results when used on coatings that has not been in service or previously holiday tested, since, in either case, there is a possibility of misleading results arising from surface contamination or salt bridging from the se of a salt test solution or handling salt water.
A holiday is defined as an area of applied coating that exhibits electrical resistance less than some specified value when that area is contacted with a wet sponge and detected with an appropriate instrument.
The specified resistance for holiday detection is 80,000 Ohms +/- 10% when measured between a wet sponge and the pipe substrate.
