Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO’s adherence to the WTO principles in the Technical
Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/TC 35, Paints and varnishes, Subcommittee SC 9,
General test methods for paints and varnishes.
This second edition cancels and replaces the first edition (ISO 16773-3:2009), which has been
technically revised. The main changes are the following:
a) the introductory element of the title, Paints and varnishes, has been omitted, because the scope
is broadened to include metals and alloys and the main element of the title has been changed to:
Electrochemical impedance spectroscopy (EIS) on coated and uncoated metallic specimens;
b) a reference to ISO/TR 16208 for dummy cells with low impedance values (10 Ω to 1 000 Ω) has
been added;
c) a reference to ASTM G106 for the precision data of low impedance measurements has been added;
d) a test report has been added.
ISO 16773 consists of the following parts, under the general title Electrochemical impedance spectroscopy
(EIS) on coated and uncoated metallic specimens:
— Part 1: Terms and definitions
— Part 2: Collection of data
— Part 3: Processing and analysis of data from dummy cells
— Part 4: Examples of spectra of polymer-coated and uncoated specimens

INTERNATIONAL STANDARD ISO 16773-3:2016(E)
Electrochemical impedance spectroscopy (EIS) on coated
and uncoated metallic specimens —
Part 3:
Processing and analysis of data from dummy cells
1 Scope
This part of ISO 16773 specifies a procedure for the evaluation of the experimental set-up used for
carrying out EIS on high-impedance coated samples. For this purpose, dummy cells are used to simulate
high-impedance coated samples. On the basis of the equivalent circuits described, this part of ISO 16773
gives guidelines for the use of dummy cells to increase confidence in the test protocol, including making
measurements, curve fitting and data presentation.
NOTE Due to the nature of the measurements, investigations of high-impedance coated samples are more
susceptible to artefacts coming from electromagnetic interferences. Therefore, this part of ISO 16773 considers
the aspects for measuring high-impedance samples by using appropriate dummy cells in a Faraday cage. However,
most manufacturers offer complementary dummy cells in the low and medium impedance range. This allows
checking the setup in the respective low impedance range.
2 Description of the dummy cells
2.1 General
A set of four equivalent circuits (dummy cells) is used to check the overall experimental arrangement.
The dummy cells are mounted separately. Two types of equivalent circui
