Metallic and Other Inorganic Coatings – Porosity Testing – Ferroxyl Testing. This standard describes the ferroxyl testing method for detecting pores in metallic and other inorganic coatings. It specifies test procedures, reagents, and evaluation methods. The method is primarily used to assess porosity in nickel, chromium, and copper coatings on steel substrates. The standard provides guidelines for sample preparation, application of the test solution, and result interpretation.
