Full title and description

St ISO 16773-1:2016 — "Electrochemical impedance spectroscopy (EIS) on coated and uncoated metallic specimens — Part 1: Terms and definitions". This part of ISO 16773 establishes and defines the terms and vocabulary used for electrochemical impedance spectroscopy measurements on coated and uncoated metallic specimens to ensure consistent use in the other parts of the ISO 16773 series.

Abstract

ISO 16773-1:2016 provides standardized terms and definitions for electrochemical impedance spectroscopy (EIS) as applied to coated and uncoated metallic specimens. It is intended to be used as the terminology reference for the other parts of the ISO 16773 series that cover data collection, processing and example spectra.

• Number of pages: 7 (core ISO document; some national adoptions include additional national front matter and pages).

Scope

This part of ISO 16773 defines the terminology to be used when performing and reporting electrochemical impedance spectroscopy (EIS) measurements on coated and uncoated metallic specimens. Its purpose is to provide a common vocabulary so that procedures, data collection (Part 2), dummy-cell processing (Part 3) and example spectra (Part 4) are described and interpreted consistently across laboratories, reports and standards.

Key topics and requirements

• Standardized definitions of EIS-related terms (impedance, admittance, phase angle, modulus, equivalent circuit elements, etc.).
• Terminology specific to coated versus uncoated metallic specimens and to high-impedance coating systems.
• Reference vocabulary to be used by the companion parts of ISO 16773 (data collection, dummy-cell processing, example spectra).
• Clear naming conventions to support repeatability and comparability of EIS measurements and reports.

Typical use and users

Used by corrosion scientists, coating formulators and manufacturers, test laboratories, quality assurance personnel, standards writers, and researchers performing electrochemical impedance spectroscopy on metallic substrates. Typical applications include coating performance assessment, corrosion monitoring, laboratory method standardization, and cross‑laboratory data comparison.

Related standards

Q: What does it cover?

A: It covers standard terms and their meanings (for example impedance-related quantities, equivalent-circuit components, specimen and test-setup descriptors) to be used in EIS measurement, reporting and in the companion parts of ISO 16773.

Q: Who typically uses it?

A: Laboratories performing EIS, coating and corrosion researchers, manufacturers of coatings and test equipment, standards developers, and QA personnel who need consistent terminology for reporting and comparing EIS data.

Q: Is it current or superseded?

A: ISO 16773-1:2016 is the current published edition (Edition 2, 2016). The earlier ISO 16773-1:2007 was withdrawn and replaced by the 2016 edition; the 2016 series was reviewed and confirmed by ISO in 2021.
