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 ).

This document was prepared by Technical Committee ISO/TC 156, Corrosion of metal and alloys.

Introduction

Corrosion of metals and alloys in high-temperature molten salts is generally an electrochemical phenomenon. Therefore, the corrosion resistance and corrosion mechanism can be evaluated via a variety of electrochemical techniques. This document describes the apparatus and procedures for electrochemical measurements in high temperature molten salts. The closely related guidelines for potentiostatic and potentiodynamic polarization measurement in aqueous solutions are described in ISO 17475.

1 Scope

This document describes the general procedure for electrochemical measurements in high-temperature molten salts using potentiodynamic polarization measurements and electrochemical impedance spectroscopy (EIS), and describes the experimental apparatus.
