    摘要: PROBLEM TO BE SOLVED: To provide a method of estimating corrosion of a water system conveniently enabling management of an oxidizing agent-based slime control agent in a job site even when a plurality of oxidizing agents coexist in the water system.SOLUTION: The method of estimating the corrosion of the water system adds a halogen-based oxidizing agent reagent in water sampled from the water system and after addition, obtains free residual halogen concentration after passing a prescribed time. The corrosion of the water system is estimated on the basis of the correlation of the free residual halogen concentration of ORP obtained previously. The prescribed time is normally 5-180 seconds, and does not exceed 5-30 seconds in particular.
