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…

ASTM International Committee B05 on Copper and Copper Alloys has created a new task group, TG9018, which will be focused on the Antimicrobial Applications of Copper and Copper Alloys. The task group was formed following the U.S. Environmental Protection Agency's announcement of its registration of copper alloys as antimicrobial materials with specific health claims. According to James Michel,…
