36、ganic coatings on metal surfaces. ISO 16773-2 specifies a dummy cell that models the properties of a high-impedance system. It gives a test procedure and set-up parameters for the collection of impedance data from the dummy cell and the coated metal specimens. It outlines a procedure for comparing t
37、he recorded spectra with the theoretical data for the dummy cell in order to establish guidelines for acceptable instrumental accuracy and limitations. It does not provide any guidance on data interpretation.ISO 16773-3 specifies the procedure used for the evaluation of the experimental results obta
38、ined from dummy cells which simulate high-impedance coated samples and it gives acceptance criteria for the values obtained.ISO 16773-4, which is informative in nature, includes some background on impedance spectra of coated metal specimens and some typical examples of spectra from actual coatings.I
39、SO/TR 16208 describes basic principles of electrochemical impedance spectroscopy (EIS) specially focusing on the corrosion of metallic materials. It also deals with how to use electrochemical apparatus, set up and connect electrical instruments, present measured data, and analyse results.DIN EN ISO
