Laboratory evaluation followed by field testing of full-size commercial anodes was initially required for acceptance of aluminum anodes. Competition and extensive anode use brought about many qualification procedures with specific purposes. Many anode applicators misdirect the use of results obtained from these tests. Indeed, it is not uncommon that results derived from assurance heat trials are assumed to convey design data. The proper choice of testing becomes more important when performance information is required in hostile environments, such as elevated and low temperature seawater and muds.

This presentation reviews a number of current pitfalls encountered in the laboratory testing area, their possible serious consequences and recommendations therein. Actual examples are given for correct and erroneous use of results from laboratory testing.
