CONTAINED IN VOL 02.04, 2005 Covers equipment and techniques for determining porosity in gold coatings, particularly electrodeposits and clad metals used on electrical contacts.
1.1 This test method covers equipment and techniques for determining porosity in gold coatings, particularly electrodeposits and clad metals used on electrical contacts.
1.2 This 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 This test method is suitable for flat surfaces, or with appropriate fixtures, for gently curved surfaces.
1.4 A variety of other porosity testing methods are described in Guide B765 and in the literature. Detailed critical reviews of porosity testing are also available. Other porosity test methods are B735, B798, B799 and B809.
1.5 This test method is specifically designed for use with gold coatings (>95% gold) on substrates of copper and nickel and their alloys. Although not covered in this standard, variations of this test method may be found useful in evaluating coatings other than gold.
1.6 The values stated in SI units are to be regarded as standard. The values in parenthesis are for information only.
1.7 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 its use. For a specific precautionary statement, see Note 1.
