NACE TM0398-98

This standard test method was developed to address a number of testing parameters involved in the laboratory corrosion testing of clean metal test specimens in static chemical cleaning solutions at temperatures above boiling (100?C [212?F]). Specifically, this standard addresses those parameters not covered in ASTM D3263 including surface-to-volume ratio, inhibitor handling, localized corrosion and pitting, and the reporting procedure, and is for use specifically by those involved in the industrial cleaning industry. The intent is that these factors will make the reported corrosion rates more useful for comparing chemical cleaning solutions and inhibitors. Because chemical cleaning solutions are used over a wide range of applications, no universal test method to cover all cases is possible. This standard is intended to be used to obtain data relevant to the cleaning of industrial equipment, such as boilers, heat exchangers, piping systems, and tanks. Note that these tests use clean test specimens in a clean solution and the severity of corrosion obtained in these tests will not be the same as if actual deposits were present.
