This part of ISO 16773 contains some typical examples of impedance spectra of high impedance coatings on metallic samples. Some guidance on interpretation is also given. Examples of spectra of low impedance systems (range from, for example, 10 ohms to 1 000 ohms) are given in ISO/TR 16208 and ASTM G 106. The responsible committee for this standard is NA 002-00-07-17 AK "Elektrochemische Methoden" ("Electrochemical methods") at DIN.
