Application Summary AI generated
This standard specifies the nitric acid vapour test method for determining the porosity of gold coatings on metal substrates. It is applied in the manufacturing and quality control of electronic components, connectors, and decorative items where gold-plated surfaces must resist corrosion. The test is used to detect pores or defects in the gold layer that could expose the underlying metal to environmental attack.
