Abstract
At first history of the picked out condenser tubes test is considered. Then the present states and problems are described. Finally modifications on the picked out copper alloy tube tests and specification on a picked out copper alloy tube test are proposed as follows : 1) Determination of causes on the corrosions. 2) Recommendation of countermeasures. 3) Assessment of fouling resistance. 4) Discussion on compatibility between corrosion control and fouling control. 5) Examination charts of EDIO.
