るものである。Samples during outdoor exposure tests are exposed to sunlight and heat during the day.
Dew condenses on its surface at night under low temperatures and high humidity, and this condensation evaporates and dries in the morning. In other words, the sample has temperature, relative humidity,
It is tested by repeating the cycle of ``light/heat irradiation - condensation - drying'' using meteorological factors such as solar radiation and precipitation, and environmental pollution factors such as sea salt particles and sulfur oxides. The weather resistance, such as corrosion resistance and light resistance, is evaluated.

で暴露を行うものである。However, these conventional methods have the following problems. Method ① involves securing the mts site and viewing the sample.
It is not economical as it requires a lot of cost and effort such as TL and management. In addition, in method (2), among various weather and environmental pollutants, 111 edible solutions such as salt solutions that are sprayed during the day receive heat and light from the sun and are evaporated and dried as corrosive substances on the sample surface. adhere to. Also, it gradually turns into a corrosive solution due to dew condensation during the night, and is evaporated to dryness again in the morning. This series of processes is repeated to cause corrosion and deterioration of the sample. In addition, in this method, in order to receive a large amount of solar radiation in test F), exposure is performed at a predetermined exposure angle at which a large amount of light is received, for example, 30 degrees.

か得られなかった。Therefore, a corrosive P4 liquid such as a salt solution sprayed onto a sample exposed at this predetermined exposure angle, e.g. ．． The attachment of the x part is less, and the lower part is attached η.
This results in a state where there are many m. Even during dew condensation, the eluted corrosive substances flow down from the top to the bottom of the sample surface. This resulted in variations in the sample surface's good condition, and it was not possible to obtain reproducibility as an exposure test that promotes corrosion deterioration.

。In an outdoor exposure test device that performs exposure tests on various industrial materials and products in a natural environment, there is a device for changing the tilt angle of the exposure stand on which the sample is attached, and when the exposure stand is horizontal, it moves parallel to the exposure surface to a specified position. It consists of a spraying device that sprays a corrosive solution onto the exposed surface, a solution supply device that supplies the corrosive solution to the spraying device, and a control device that controls the angle change time of the exposure stand and the spraying time of the corrosive solution. An outdoor corrosion acceleration exposure device characterized by automatically and periodically changing the inclination angle of the frame and spraying a corrosive solution.
