Description / Abstract:
This part of ISO 16773 gives guidelines for optimizing the
collection of EIS data with focus on highimpedance systems. High
impedance in the context of intact coatings refers to systems with
an impedance greater than
109
Ω⋅m2. This does not
preclude measurements on systems with lower impedance. For uncoated
samples extra information can be found in ISO/TR 16208.
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.
