Full Description

1.1 These test methods cover the apparatus and procedures for detecting pinholes and holidays in coatings used to protect pipelines.
1.2 Method A is designed to detect pinholes and holidays in thin-film coatings from 0.025 mm to 0.254 mm (1 mils to 10 mils) in thickness using ordinary tap water and an applied voltage of less than 100 V d-c. It is effective on films up to 0.508 mm (20 mils) thickness if a wetting agent is used with the water.
1.3 Method B is designed to detect pinholes and holidays in thick-film coatings >0.508 mm (20 mils) This method can be used on any thickness of pipeline coating and utilizes applied voltages between 3.4 and 35 kV d-c.
1.4 The values stated in SI units to three significant decimals are to be regarded as the standard. The values given in parentheses are for information only.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
