Description

ASTM G199-09-e1-Reapproved2020

Active Standard: Standard Guide for Electrochemical Noise Measurement

ASTM G199

Scope

1.1 This guide covers the procedure for conducting online corrosion monitoring of metals by the use of the electrochemical noise technique. Within the limitations described, this technique can be used to detect localized corrosion activity and to estimate corrosion rate on a continuous basis without removal of the monitoring probes from the plant or experimental cell.

1.2 This guide presents briefly some generally accepted methods of analyses that are useful in the interpretation of corrosion test results.

1.3 This guide does not cover detailed calculations and methods; rather it covers a range of approaches that have found application in corrosion testing.

1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
