Metallic and Other Inorganic Coatings – Determination of Porosity in Gold Coatings on Metals – Test with Nitric Acid Vapor. This standard outlines a method for determining the porosity of gold coatings on metals using nitric acid vapor. Gold coatings are commonly used to protect metals against corrosion, but porosity can affect their effectiveness. The standard provides a methodology to detect and evaluate the presence of pores that may lead to premature corrosion of the underlying metal.
