Electrochemical impedance spectroscopy (EIS) on coated and uncoated metallic specimens - Part 2 : collection data

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. ISO 16773-2:2016 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.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
