Zusammenfassung:	To provide a dew-point corrosion test method which can sufficiently simulate dew-point corrosion due to corrosive gas.SOLUTION: A test method includes: a test piece attachment step (#20) of arranging a test piece on the inside of a test container; and a test step (#30) of while supplying corrosive gas and steam to the test container and keeping it in a high temperature state, maintaining the surface of the test piece at a lower temperature than the corrosive gas and steam.SELECTED DRAWING: Figure 6 【課題】腐食性ガスによる露点腐食を十分に模擬できる露点腐食試験方法を提供する。【解決手段】試験方法は、試験容器の内側に試験片を配置する試験片取付け工程（＃２０）と、腐食性ガス及び水蒸気を試験容器に供給して高温の状態に維持しつつ、試験片の表面を腐食性ガス及び水蒸気よりも低温に維持する試験工程（＃３０）と、を含む。【選択図】図６
