PROBLEM TO BE SOLVED: To provide a weathering test method capable of generating natural condensation in a state more similar to the natural state, even in the case of an armoring material having a low thermal conductivity.;SOLUTION: This weathering test method is performed as follows: a sample of the armoring material is stationed in a test tank 1 storing a humidification means by a humidifying heater 5 and an air agitation means by an agitating fan 7; the test tank 1 inside is kept in a low-temperature high-humidity state for a fixed time, to thereby cool uniformly the front and the back of the whole sample; then, the humidifying heater 5 is heated in the state where the agitating fan 7 is stopped; while humidifying the test tank 1 inside, the room temperature is raised; after elapse of a prescribed time after rise of the humidity and the temperature inside the test tank 1 is started, the agitating fan 7 is operated; hereby, dew condensation occurs on the sample surface by delaying a temperature rise on the sample surface furthermore than a rise of the room temperature.;COPYRIGHT: (C)2007,JPO&INPIT
