摘要： PURPOSE:To provide a test method by which an outcome having approximation to deterioration at outdoor exposure (for example, the size of the peeling off area of a knife edge portion and the number and area or the like of a swelling) can be obtained in a short time in the case of a coated film sample. CONSTITUTION:Firstly, a salt water spraying test is conducted to the coated film surface of a coated film sample for a fixed time (two hours). Next, a drying test is conducted for a fixed time (four hours), and during this drying test, a light source is first lighted, and light radiation energy is given to the coated film surface, and the coated film surface is made to arrive at a predetermined temperature (60 deg.C) while a temperature difference is being generated between the coated film surface and a foundation, and afterwards, the light source is put out, and at the same time hot air having the same temperature with that of the coated film surface is blown to the coated film sample for the remaining time, and the temperature difference between the coated film surface and the foundation is removed. Lastly, a moisture test is conducted for a fixed time (two hours). This series of conditions is repeated by the predetermined number of times as a one cycle test.

摘要： PURPOSE:To accurately accelerate and reproduce corrosion and deterioration of a sample by generating dew drops of a constant grain diameter in a weather resistance tester which perform a dew drop test. CONSTITUTION:When a light source 3 is extinguished to make the interior of a test tank 2 reach a preset temperature and humidity, the rear of a sample and the rear of a board 28 of a dew drop sensor 1 are cooled by water in a water tank 34 set at a temperature slightly higher than a dew point temperature obtained from the preset temperature and humidity. Humidification is started from the undewing state by keeping the temperature constant in the test tank 2 to increase the humidity in the test tank 2 and to decrease the temperature of the sample 4 below the dew point temperature, thereby causing dew drops on the surface of the sample 4. Further, a constant state of dewing is maintained by adjusting the humidity in the test tank 2 from outputs corresponding to the dewing states of the dew drop sensor 1.

摘要： PURPOSE:To accelerate the reproducibility of the corrosion form by the acidic rain by forming an acid solution having a specific value of pH by dissolving each prescribed quantity of ions into water and repeating the mist injection, drying and damping cycles under each specific condition. CONSTITUTION:Sulfate, nitride, chloride, ammonium, Mg, K, and Na ions are dissolved in 1l water by 190-390, 50-230, 38-190, 37-120, 5-41, 6-2, and 40-350mg, and an acidic solution having a pH of 5-2 is prepared, and allowed to correspond to the acidic rain. This solution is jetted on a sample surface in an environment where the temperature 15 controlled to a set value of 30-40 deg.C, and a uniform film consisting of the extremely fine mists of the solution is formed. Then, the sample surface is kept at a temperature of 50-80 deg.C by an artificial light source in substitution 4 the solar beam and the radiation heat environment temperature and dried. Further, the sample is kept for a certain time in a damped environment of 90-95%RH at a certain temperature of 30-60 deg.C. After the repetition of these mist injection, drying and damping cycles, the reproducibility of the corrosion form such as stains and erosion by the acidic rain can be accelerated, and the acidic mist test can be carried out.

摘要： PURPOSE:To evaluate the fatigue and the weatherability of a sample readily by attaching the sample to a holder having a metal coil whose shape is changed by the change in ambient temperature, and imparting tensile stress and the like repeatedly. CONSTITUTION:In the fatigue weatherability test of a sample 2 which is attached to a holder 1, the holder is attached to a sample frame 14 of, e.g. an accelerated weatherability tester 11. Then, the temperature in a test chamber 12 is changed due to ON and OFF of a light source and water spraying in addition to the regulation of the temperature in the test chamber. Therefore, a coil 7 repeats the expansion and the contraction because of the temperature change. The coil 7 expands to the maximum degree when the temperature is, e.g. 70 deg.C. The coil 7 returns to the original state at 20 deg.C. The coil is expanded and contracted in proportion to the temperature in this range. Therefore, the specified tensile stress is repeatedly applied on the sample so that the generating force is changed, and the fatigue weatherability test can be conducted effectively.

摘要： PURPOSE:To simultaneously take a shot test in the same test tank at different temperature by holding the temperature of cooling water supplied to each electron cooling element constant and adjusting flow rates individually. CONSTITUTION:Cooling water which circulates and antifreeze liquid are used, the liquid is held at 0 deg.C, and the cooling water from a cooling water tank 26 is supplied to plural electron cooling elements 5a-5c through a cooling water circuit 6, a cooling water circuit entrance 7, and a flow rate regulating valve 8. The cooling water circuit 6 is coupled with the plural electron cooling elements 5 in parallel, so the amount of cooling water supplied to each cooling element 5 is individually controllable. Thus, the flow rate of the cooling water supplied to each cooling element 5 is controlled individually by the flow rate controller 8 to supply the cooling water of the same temperature, thereby controlling the respective cooling elements 5 to different temperatures. Consequently, the shot test is taken at the different temperatures simultaneously.

摘要： PURPOSE:To obtain a wet state easily without mounting a complicated humidifier and to achieve a complete dry with a construction of checking the evaporation of water in a drying test while dew forming conditions can be obtained with ease. CONSTITUTION:With a vertical shaft 3 down to the lowest end, a sample is immersed in a liquid. The temperature of the liquid control is adjusted by controlling a heater 11 according to the setting of a temperature adjustor 10. When the drying conditions are entered by a program signal, a crank mechanism 6 is driven by a motor 9 to lift the vertical shaft 3 and when it reaches the highest end, a square shield plate 12 hung securely on a sample hanging arm 4 sticks out to the entire circumference of the inner wall of an immersion tank ad makes an isolation between an air tank 1 and the immersion tank 2 by sealing with packing 13 fixed on a square rim. At the same time, a blower 14 operates to send outside air into a hot air box 15 and the hot air generated by heating with a heater 16 enters the air tank through an air port 7 to dry the sample. The wet temperature is adjusted with the control of the heater 11 according to the setting of a temperature adjustor 19 so that evaporated water of the immersion liquid enters the air tank 1 passing through a clearance between the shield plate 12 and the packing 13.
