Paints and varnishes. Electrochemical impedance spectroscopy (EIS) on high-impedance coated specimens. Processing and analysis of data from dummy cells | Status: Revised, Superseded, Withdrawn

1 Scope This part of ISO 16773 specifies a procedure for the evaluation of the experimental set-up used for carrying out EIS on high-impedance coated samples. For this purpose, dummy cells are used to simulate high-impedance coated samples. On the basis of the equivalent circuits described, this part of ISO 16773 gives guidelines for the use of dummy cells to increase confidence in the test protocol, including making measurements, curve fitting and data presentation.
