Guidelines on electrochemical corrosion measurements (EFC 4) PDF

Introduction

At the present time electrochemical test methods in corrosion are becoming more diverse and, as a consequence, new techniques have been added to those well established. Each technique has limitations and has requirementsfor condi tions to be satisfied for practical application. This subject was the topic of an international workshop held at Ferrara, Italy,' 11-13 September 1985, organised by the European Federation of Corrosion Working Party on Physico-Chemical Methods of Corrosion Testing [1].;This Workshop outlined the range of practical application of electrochemical corrosion testing as well as reaching conclusions concerning the use, significance and limitations of various methods. However, this meeting, and others, on electrochemical corrosion measurements have generally not provided specific information on how experiments should be performed [2-4]. It was the 'Working Party's intention to fulfil this requirement with the compilation of this booklet ..In undertaking this task, members were confronted with a great variety of techniques to be considered, although, inevitably, the same experimental principles are involved with the various techniques. Various practical aspects in cond ucting experiments, both in the laboratory and in the field, have been considered in achieving the objective of this work.

There is a notable absence of specifications or codes of practice on the use of electrochemical corrosion testing andit is hoped that these guidelines will fill this gap in corrosion science.
