Paints and varnishes — Electrochemical impedance spectroscopy (EIS) on high-impedance coated specimens — Part 2: Collection of data

Apstrakt

ISO 16773-2:2007 provides guidance on optimizing the collection of EIS data from high-impedance systems. High impedance in the context of intact coatings refers to systems with an impedance greater than 109 ohm·cm2. This does not preclude measurements on systems with lower impedance.
ISO 16773-2:2007 deals with

instrumental set-up: requirements and pit-falls;
data validation: checking the measurement range and the accuracy of the data;
performing an EIS measurement: specimen considerations and instrumental parameters;
the experimental results: different methods of presenting EIS data.

It does not give guidelines for the interpretation of the data.
