Scope

This document specifies the method and criteria for monitoring corrosion states of heat exchange tubes, heat exchange plates and other components made of stainless steel in industrial cooling water by combination of polarization resistance and corrosion potential.
This document is applicable to the monitoring of the corrosion states of stainless steel in industrial cooling water or similar media, as well as the monitoring of the corrosiveness of industrial cooling water. The cooling water is generally taken from natural water, tap water and reclaimed water. It is applicable to industrial cooling water with pH value of 5,0 to 11,0, temperature of 0 °C to 60 °C, and conductivity higher than 20 μS/cm.
