Описание (английский):

ISO/TR 16208:2014 describes basic principles of electrochemical impedance spectroscopy (EIS), specially focusing on the corrosion of metallic materials. It also deals with how to use electrochemical apparatus, set up and connect electrical instruments, present measured data, and analyse results. However, a more detailed description of this methodology can be found in ISO 16773-1 and ISO 16773-2.

Overview

ISO/TR 16208:2014 - "Corrosion of metals and alloys - Test method for corrosion of materials by electrochemical impedance measurements" - is a Technical Report that explains the basic principles and practical use of electrochemical impedance spectroscopy (EIS) for corrosion assessment. The report focuses on how to set up electrochemical apparatus, connect potentiostats and electrodes, record impedance data (Bode and Nyquist), and analyse and present results. It is an introductory, application-focused guide and points to ISO 16773‑1/2 for more detailed methodology.

Key Topics

Fundamentals of EIS: complex impedance representation (real/imaginary parts), magnitude |Z|, phase angle, and the use of Bode and Nyquist plots.

Simple corroding system model: equivalent circuits for metal/solution interfaces including solution resistance (Rs), polarization/charge transfer resistance (Rp/Rct), and double-layer capacitance (Cdl) or constant phase element (CPE) for non-ideal capacitive behaviour.

Instrumentation & apparatus: recommendations on potentiostats, reference, counter and working electrodes, test cells, Luggin capillaries and electrolyte choice.

Specimen and solution preparation: considerations for preparing metal specimens and test electrolytes to ensure steady-state conditions during measurement.

Dummy cell & instrument validation: use of dummy circuits (PCB-mounted components) to test and validate measurement chains and data processing.

Data collection & analysis: presentation of measured impedance, use of Kramers–Kronig relations, interpretation of impedance spectra, and relationships between Rp and corrosion current (Icorr) where applicable.

Reporting: essential content for a test report and informative annexes on dummy cell design and data analysis.

Applications

ISO/TR 16208:2014 is practical for professionals who need to apply EIS to corrosion problems, including:

Corrosion engineers and materials scientists assessing metal corrosion rates, passive film integrity, and localized attack.

Coating and surface-treatment developers evaluating barrier properties of coatings and coating degradation.

Test laboratories performing routine EIS corrosion testing, quality control, and validation of instrumentation.

R&D teams using impedance data to model electrochemical mechanisms or estimate polarization/charge-transfer resistance.

Keywords: ISO TR 16208:2014, electrochemical impedance spectroscopy, EIS, corrosion testing, Nyquist plot, Bode plot, CPE, potentiostat, polarization resistance.
