... confronted with an under deposit corrosion issue. This paper summarizes these tests and provides a methodology to choose which methods relate to the situation at hand and how well each method applies to such situation. An attempt is made to assess the semantics of calling UDC a corrosion mechanism. EXAMPLES...
