METHOD FOR MEASURING METAL CORROSIVENESS OF SOLUTION

摘要

PROBLEM TO BE SOLVED: To provide a method for measuring metal corrosiveness of an aqueous solution for easily measuring metal corrosiveness without causing judgement errors by an operator. SOLUTION: The electric conductivity of stored water as an aqueous solution containing a metal dipped therein is measured. If the measured value exceeds 1.0 mS/cm, it is determined that chloride ion contained in the stored water exceeds 300 ppm such that the metal is highly corrosive. COPYRIGHT: (C)2004,JPO
