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

Introduction
This International Standard describes the determination of the anticorrosive properties of organic
coatings by means of the accelerated cyclic electrochemical technique (ACET). The method is based on
the so called AC/DC/AC procedure. This technique allows comparing the protective and anticorrosive
properties of different coating systems on metal in short times and in a qualitative and quantitative
way. ACET consists of the application of cycles of EIS (electrochemical impedance spectroscopy)
measurements, cathodic polarizations and potential relaxation. Degradation of the coating system is
accelerated by the cathodic polarization. EIS and potential relaxation monitor the change of the coating
system induced by the cathodic polarization. The technique evaluates the permeability of the coating
and properties which can be attributed to adhesion to the substrate.
