NF EN ISO 16773-2
Paints and varnishes - Electrochemical impedance spectroscopy (EIS) on high-impedance coated specimens - Part 2 : collection 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.

<p>ISO 16773-2:2016 gives guidelines for optimizing the collection of EIS data with focus on high-impedance systems. High impedance in the context of intact coatings refers to systems with an impedance greater than 109 Ω⋅cm2. This does not preclude measurements on systems with lower impedance. For uncoated samples extra information can be found in ISO/TR 16208.</p> <p>ISO 16773-2:2016 deals with the following:</p> <p>- instrumental set-up: requirements and pit-falls;</p> <p>- data validation: checking the measurement range and the accuracy of the data;</p> <p>- performing an EIS measurement: specimen considerations and instrumental parameters;</p> <p>- the experimental results: different methods of presenting EIS data.</p> <p>These guidelines are intended to ensure the acquisition of EIS data that can be used to study the performance of the specimen. This part of ISO 16773 does not give guidelines for the interpretation of the data.</p>
