Localized corrosion, such as pitting, cracking or crevice corrosion, can be destructive to process equipment, but if it is detected early enough, potential damage can be minimized or avoided. A new ASTM International standard provides a means for electrochemical testing for corrosion. The new standard, G199 , Guide for Electrochemical Noise Measurement, was developed by Subcommittee G01.11 on…
