Scope
This document describes a method for evaluating the crevice corrosion resistance of stainless steel and its alloys in oxidizing chlorine-containing solutions.
This document is suitable for measuring the critical crevice corrosion temperature of tube/rod specimens or plate specimens with the same composition that suffer from crevice corrosion due to chemical reactions, but differs from the electrochemical method in ISO 18070.
This document specifies the device and procedure for measuring the crevice corrosion temperature of cylindrical tube specimens.
