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

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.
