Paints and varnishes - Electrochemical impedance spectroscopy (EIS) on high-impedance coated specimens - Part 3: Processing and analysis of data from dummy cells (ISO 16773-3:2009)
ISO 16773-3:2009 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, ISO 16773-3 gives guidelines for the use of dummy cells to increase confidence in the test protocol, including making measurements, curve fitting and data presentation.
