Recent Developments in Standards for Electrochemical Corrosion Testing


Electrochemical methods are now widely used in corrosion testing and evaluation. About one-third of all research articles recently published on corrosion science and technology have some electrochemical components in the studies reported. New methods continue to be developed and standardized. The purpose of this paper is to highlight the newer standards and discuss changes made to existing standards developed by ASTM Subcommittee G01.11 on Electrochemical Methods. Among the newer methods discussed are ASTM G192, Standard Test Method for Determining the Crevice Repassivation Potential of Corrosion-Resistant Alloys Using a Potentiodynamic-Galvanostatic-Potentiostatic Technique, and ASTM G217, Standard Guide for Corrosion Monitoring in Laboratories and Plants with Coupled Multielectrode Array Sensor Method. Older standards that have been updated are also discussed, including ASTM G5, Standard Reference Method for Making Potentiodynamic Anodic Polarization Measurements, and ASTM G69, Standard Test Method for Measurement of Corrosion Potentials of Aluminum Alloys. Some outstanding issues with existing standards and suggestions for new standards are provided in the discussion.
