Electrochemical impedance spectroscopy (EIS) on coated and uncoated metallic specimens - Part 2: Collection of data (ISO 16773-2:2016); German version EN ISO 16773-2:2016
Elektrochemische Impedanzspektroskopie (EIS) an beschichteten und unbeschichteten metallischen Proben - Teil 2: Datenerfassung (ISO 16773-2:2016); Deutsche Fassung EN ISO 16773-2:2016
Overview
This part of ISO 16773 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 Ohm×cm2. This does not preclude measurements on systems with lower impedance. This part of ISO 16773 deals with the following: - 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. 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. These guidelines are intended to ensure the acquisition of EIS data that can be used to study the performance of the specimen. The responsible committee for this standard is NA 002-00-07-17 AK "Elektrochemische Methoden" ("Electrochemical methods") at DIN.
