1.1This practice covers procedures for determining discontinuities using two types of test equipment:

1.1.1Test Method A—Low Voltage Wet Sponge, and

1.1.2Test Method B—High Voltage Spark Testers.

1.2This practice addresses metallic substrates. For concrete surfaces, refer to Practice D4787.

1.3The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.4This 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.

1.5This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
