ActiveMetallic coatings--Porosity tests--Humid sulfur(flowers of sulfur) test
金属覆盖层 孔隙率试验 潮湿硫(硫华)试验
Application Summary AI generated
This standard specifies a test method for detecting porosity in metallic coatings by exposing specimens to a humid sulfur atmosphere. It is applied in manufacturing and quality control to assess the corrosion resistance and coverage of coatings on metals, particularly for components like fasteners, electronic connectors, and decorative hardware. The test is used to identify discontinuities in coatings that could lead to substrate corrosion in service environments.
