Electrochemical techniques are available for monitoring the long-term performance of materials in the plant environment. Many of these techniques such as current and potential logging have the ability to collect vast quantities of data in relatively short time frames. These needs to resolved into more meaningfi.d information as the time required to analyse all this data is too great. Statistic analyses can be undertaken as the data is collected to help identifi periods of interest and allow these periods of activity to be examined in detail.
