Class Information
Number: 205/776
Name: Electrolysis: processes, compositions used therein, and methods of preparing the compositions > Electrolytic analysis or testing (process and electrolyte composition) > For corrosion > Testing by internal battery action
Description: Subject matter in which a material or system is tested for corrosion without an external source of electric current; usually the electrolytic current is derived from an internal chemical reaction (e.g., galvanic action, etc.).
