1.1 This test method covers equipment and techniques for determining porosity in noble metal coatings, particularly electrodeposits and clad metals used on electrical contacts.
1.2 The test method is designed to show whether the porosity level is less or greater than some value which by experience is considered by the user to be acceptable for the intended application.
1.3 Other porosity testing methods are outlined in Guide B765. Detailed critical reviews of porosity testing are also available. Other porosity test methods are B735, B741, B799, and B809.
1.4 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 and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Sections 7 and 8.
1.5 The values stated in SI units are to be regarded as standard. The values in parentheses are for information only.
