Metallic and Other Inorganic Coatings – Simultaneous Measurement of Individual Layer Thickness and Potential in Nickel Coatings (STEP Test). ISO 16866:2020 describes the STEP test, a method for simultaneously measuring layer thickness and potential of individual layers in nickel coatings. This test analyzes multilayer coatings, particularly where corrosion resistance and electrical functionality are critical. By measuring each layer’s potential and thickness, the quality and protective properties of the coating can be assessed. The STEP test is vital for industries requiring high-performance coatings, such as electronics and automotive, where both corrosion protection and electrical conductivity are paramount.
