Standard Guide for Electrochemical Noise Measurement

Importancia y uso:

5.1 Use of this guide is intended to provide information on electrochemical noise to monitor corrosion on a continuous basis.

5.2 This guide is intended for conducting electrochemical noise measurements, both in the laboratory and in-service environments (36).

5.3 This technique is useful in systems in which process upsets or other problems can create corrosive conditions. An early warning of corrosive attack can permit remedial action before significant damage occurs to process equipment (37).

5.4 This technique is also useful when inhibitor additions are used to control the corrosion of equipment. The indication of increasing corrosion activity can be used to signal the need for additional inhibitor (38).

5.5 Control of corrosion in process equipment requires knowledge of the rate or mechanism of attack on an ongoing basis. This technique can be used to provide such information in a digital format that is easily transferred to computers for analysis (39) .
