Metallic coatings. Determination of porosity in gold coatings on metal substrates. Nitric acid vapour test1 Scope This International Standard specifies equipment and a method for using nitric acid vapour to determine porosity in gold coatings, particularly electrodeposits and clad metals used on electrical contacts. This method is designed to show whether the porosity level is less than or greater than some value that, by experience, is considered by the user to be acceptable for the intended application. It is suitable for inlays or claddings containing

Resistance to reprocessing requirement has been clarified in 6

The method is used to investigate the flexural behaviour of the test specimens and to determine the flexural strength
