Inorganic Coatings – Test Method for Electroplated Coatings of Gold and Gold Alloys – Part 3: Porosity Testing. ISO 4524-3:2021 describes test methods for determining the porosity of electroplated coatings of gold and gold alloys. Porosity is a critical factor in the protective properties of these coatings, particularly in electronics and jewelry, where they protect the substrate from corrosion and wear. The standard explains how porosity can be measured and quantified using methods such as electrochemical testing and visual inspection. Detecting and evaluating pores ensures the coating meets the requirements for its intended application.
