Japanese Patent No. 2942444

  By the way, in the case of such a weather resistance test, it is generally required to improve convenience.

  Therefore, it is desirable to provide a weather resistance tester and a weather resistance test method that can improve the convenience when performing a weather resistance test.

  A weather resistance tester according to an embodiment of the present invention exposes a first surface of a test tank and a sample having a first surface and a second surface that are disposed in the test chamber and face each other to the outside. One or a plurality of sample holding boxes for holding the sample in a state, and a control unit for performing operation control when performing a weather resistance test on the sample are provided. This control unit generates condensation on only one of the first surface and the second surface of the sample in the high temperature test mode in which the weather resistance test is performed with the temperature in the sample holding box raised. The operation control is performed so that both the dew condensation test mode in which the weather resistance test is performed in the wet state and the two test modes are individually executed.

  A weather resistance test method according to an embodiment of the present invention includes one or more samples that hold a sample with the first surface of the sample having the first surface and the second surface facing each other exposed to the outside. When the holding box is placed in the test tank and the weather resistance test is performed on the sample, a high temperature test mode in which the weather resistance test is performed in a state where the temperature in the sample holding box is raised, and the first surface of the sample And a condensation test mode in which a weather resistance test is performed in a state where condensation is generated only on one of the second surfaces, and operation control is performed so that both test modes are individually executed. is there.

  In the weather resistance tester and the weather resistance test method according to an embodiment of the present invention, the operation during the weather resistance test is performed so that both the high-temperature test mode and the dew condensation test mode are executed individually. Control is performed. Thereby, a weather resistance test under various test conditions is realized.

  Here, a light source that emits radiated light is further provided in the test chamber. In the high temperature test mode, a sample holding box having a black housing is used, and the black housing and the sample emitted from the light source are used. The temperature in the sample holding box may be raised by using the radiated light that has passed through. In this case, since the temperature in the sample holding box is likely to rise using the black casing and the synchrotron radiation (can be efficiently set to a high temperature state), convenience in executing the high temperature test mode is improved. .

  In this case, you may make it arrange | position a black member and a heat insulation member on the opposite side to the holding surface of the sample in a sample holding box, respectively. In this case, using the black member, the temperature in the sample holding box is further easily increased (can be set to a high temperature state more efficiently). Further, by using the heat insulating member, heat radiation from the sample holding box is suppressed, and a high temperature state is easily maintained. As a result, the convenience in executing the high temperature test mode is further improved.

  In addition, a through-air amount adjusting valve is provided on the black housing, and the temperature in the sample holding box is adjusted by adjusting the opening / closing amount of the through-air amount adjusting valve during the high temperature test mode. Also good. In this case, for example, when a plurality of sample holding boxes are provided in the test tank, the temperature in each sample holding box can be set individually. As a result, the convenience in executing the high temperature test mode is further improved.

  Here, in the dew condensation test mode, a sample holding box having a white housing with a built-in heat storage member may be used. In this case, since it is a white casing and a heat storage member is built in, it is a white casing even when, for example, external light (for example, radiated light from a light source) is irradiated on the sample holding box. The temperature in the sample holding box is unlikely to rise (it is easy to maintain a low temperature state). Further, since the heat storage member is built in, the temperature in the sample holding box can be easily maintained at the low temperature state or the high temperature state even when the temperature in the test chamber changes. Furthermore, since it is not necessary to install a cooling device, a heating device, or the like in the sample holding box, the structure of the sample holding box becomes simple and the cost can be reduced.

  Further, as the above dew condensation test mode, the first dew condensation test mode in which the weather resistance test is performed in a state where the dew condensation is generated only on the first surface of the sample, and the dew condensation is generated only on the second surface of the sample. You may make it provide the 2nd dew condensation test mode which performs a weather resistance test in a state. In this case, both the dew condensation test for generating dew condensation only on the first surface of the sample and the dew condensation test for generating dew condensation only on the second surface of the sample can be realized individually.

  In this case, a liquid ejecting mechanism for ejecting liquid to a surface opposite to the surface on which the sample is held in the sample holding box is further provided, and when the control unit is in the first dew condensation test mode, Condensation may be generated only on the first surface of the sample by increasing the humidity of the sample and lowering the temperature in the sample holding box by using the liquid injection by the liquid injection mechanism.

  In addition, in the second dew condensation test mode, the control unit lowers the temperature in the test chamber below the temperature in the sample holding box so that dew condensation occurs only on the second surface of the sample. Also good.

  Here, when the control unit is in the dew condensation test mode, the state of dew condensation that occurs only on the one surface may be controlled using a dew condensation sensor. In this case, since the state of condensation can be adjusted with high accuracy, reproducibility in the condensation test mode is improved.

  In addition, as said sample, the thing using glass materials (automobile glass etc.) etc. are mentioned, for example.

  According to the weather resistance tester and the weather resistance test method according to an embodiment of the present invention, the weather resistance test is performed so that both the high temperature test mode and the dew condensation test mode are performed individually. Since the operation control is performed, a weather resistance test under various test conditions can be realized. Therefore, it is possible to improve convenience when performing the weather resistance test.

2. Modified example

<1. Embodiment>
[Schematic configuration]
FIG. 1 schematically shows a schematic configuration example of a weather resistance tester (weather resistance tester 1) according to an embodiment of the present invention. FIG. 2 schematically shows an example of a cross-sectional configuration (X-Y cross-sectional configuration) taken along the line II-II in FIG. In addition, since the weather resistance test method which concerns on one embodiment of this invention is embodied in the weather resistance test machine 1 of this Embodiment, it is demonstrated collectively below.

  The weather resistance tester 1 performs a weather resistance test under accelerated environmental conditions on a sample (test piece) 9 made of various materials arranged in a test tank 10. As shown in FIGS. 1 and 2, the weather resistance tester 1 includes a light source 11, a pair of sample mounting frames 12a and 12b, a sample holder 13, A sample holding box 14 for holding the sample 9, a liquid ejecting mechanism 15, a light receiver 16, and a black panel thermometer 17 are provided. As shown in FIG. 1, the weather resistance testing machine 1 also includes a rotating shaft 120 and a control unit 18.

  The sample 9 is a plate having a first surface (front surface) and a second surface (back surface) facing each other. In addition, as above-mentioned as a material of the sample 9, various materials are mentioned, However, Glass, a transparent plastic, etc. are mentioned as an example. Moreover, as a use of the sample 9 in the case of this glass material, the object for vehicles (automobile etc.) is mentioned. That is, as an example of the sample 9, there is a glass for automobiles.

  The light source 11 is disposed in the vicinity of the center in the test chamber 10 so as to extend along the Z-axis direction. The light source 11 emits radiated light Lout around the test chamber 10 (along the XY plane direction). The light source 11 is constituted by a lamp light source such as a xenon arc lamp, a sunshine carbon arc lamp, an ultraviolet carbon arc lamp, a metal halide lamp, or an ultraviolet fluorescent lamp.

  Each of the sample mounting frames 12a and 12b is an annular frame disposed in the XY plane so that the light source 11 is at the center position. As shown in FIG. 1, each of these sample mounting frames 12a and 12b has a light source along a rotational direction R2 that is the same as the rotational direction R1 by rotating the rotational shaft 120 along the rotational direction R1. The rotation operation is performed at a constant speed centered on 11 (rotation center). As a result, as shown in FIG. 2, each sample holder 13, each sample holding box 14, light receiver 16, and black panel thermometer 17, which will be described later, also rotate around the light source 11 along the rotation direction R <b> 2. It has come to be.

  As shown in FIG. 1, the sample holder 13 is attached so as to connect the sample attachment frames 12a and 12b, and is attachable to and detachable from the sample attachment frames 12a and 12b. Each sample holder 13 has a sample mounting surface facing the light source 11. As shown in FIG. 2, a sample holding box 14, a light receiver 16, or a black panel thermometer 17 described later is disposed on the sample mounting surface. Such a plurality of sample holders 13 as a whole have a polygonal shape corresponding to the number of them on the XY plane, for example, as shown in FIG. In other words, the plurality of sample holders 13 are arranged side by side so as to form a polygon on the sample mounting frames 12a and 12b.

(Sample holding box 14)
As described above, the sample holding box 14 is a box (sample holding box for a weather resistance tester) for holding the sample 9 in the test tank 10. As shown in FIG. 2, a plurality of sample holding boxes 14 are arranged in the test tank 10 in this example. As will be described in detail later, such a sample holding box 14 holds the sample 9 with the surface of the sample 9 exposed to the outside (inside the test chamber 10), and has a box shape. doing. A detailed configuration example and an operation example of the sample holding box 14 will be described later (FIGS. 4 to 6).

As shown in FIG. 1, the liquid ejecting mechanism 15 is a mechanism (spray nozzle) that ejects a predetermined liquid W onto a surface (back surface) opposite to the holding surface (front surface) of the sample 9 in the sample holding box 14. ). In this example, the liquid ejection mechanism 15 is disposed on the back side of the sample holding box 14 in the test tank 10. Examples of the liquid W include water (H ₂ O) having a water temperature of about 10 ° C.

  The light receiver 16 is for measuring the irradiance of the radiated light Lout emitted from the light source 11 (illuminance meter), and is mounted on the sample mounting frames 12a and 12b. Specifically, for example, as shown in FIG. 2, the light receiver 16 is arranged on the sample holder 13 on which the sample holding box 14 is not attached (not arranged) on the sample attachment frames 12a and 12b. Has been. The light reception data (light reception value) obtained by the light receiver 16 is transmitted to the control unit 18 described later.

  As shown in FIG. 2, the black panel thermometer 17 is mounted on the sample holder 13 (sample mounting surface), and is a thermometer for measuring temperature information representative of the surface temperature of the sample mounting surface. . This temperature information includes a component in which the light energy of the radiated light Lout is heated, an environmental temperature component in the test chamber 10, a heat transfer component due to wind flowing through the sample surface, and the like. Such a black panel thermometer 17 includes, for example, a heat sensitive body such as a bimetal, a platinum resistor, a thermistor, or a thermocouple, and a plate painted in black.

  The control unit 18 is a part that controls the operation of the weather resistance testing machine 1 as a whole. For example, the control unit 18 controls the irradiance on the sample 9 by controlling the radiation intensity of the light source 11 based on the light reception data obtained by the light receiver 16 as one of such control operations. have. Further, when the control unit 18 selects the black panel thermometer 17 as the temperature control reference, the control unit 18 performs operations of a heater, a refrigerator, and the like (not shown) based on the temperature information obtained by the black panel thermometer 17, respectively. By controlling, it has the function (temperature control function) which controls the temperature in the test chamber 10. Alternatively, when the temperature control reference is selected as the thermometer in the test tank 10, the control unit 18 similarly uses the temperature information obtained by the thermometer in the test tank 10 to similarly store the temperature in the test tank 10. It has a function to control temperature (temperature control function). Furthermore, the control unit 18 has a function (humidity control function) for performing humidity control in the test tank 10 based on the relative humidity calculated from the relationship between the dry bulb temperature and the wet bulb temperature. In this way, the control unit 18 controls the three elements (irradiance, black panel temperature (or dry bulb temperature), and relative humidity) that influence each other at the same time. In addition, the control unit 18 can also perform temperature control based on two criteria of the temperature control, that is, the black panel thermometer 17 and the thermometer in the test tank 10. In this case, the control unit 18 also adds control of the air volume circulating in the test tank 10 based on the temperature information obtained from the black panel thermometer 17 and the thermometer in the test tank 10, so that the black panel The temperature control of both the thermometer 17 and the thermometer in the test chamber 10 is performed.

  Here, particularly in the present embodiment, the control unit 18 performs, for example, the following operation control when performing a weather resistance test on the sample 9. That is, the control unit 18 performs operation control so that various test modes (for example, a high temperature test mode and a dew condensation test mode) described later are individually executed. Details of the operation control in the weather resistance test in the control unit 18 will be described later.

[Operation and action / effect]
(A. Basic operation)
In the weather resistance tester 1, the emitted light Lout is emitted from the light source 11 in the test tank 10 as necessary. At this time, the sample mounting frames 12 a and 12 b to which the plurality of sample holding boxes 14, the light receivers 16, and the black panel thermometers 17 are mounted perform rotation operations around the light source 11. Thereby, the radiated light Lout is irradiated with respect to the sample 9 in each sample holding box 14 under accelerated environmental conditions (accelerated test environment). By radiating such radiated light Lout for a predetermined test time (for example, several hours to several thousand hours), the degree of deterioration of each sample 9 (material) is evaluated, and a weather resistance test is performed. Further, in addition to the above-described irradiation test by the emission of the light source 11, there is also a dark test in which the temperature and relative humidity in the test tank 10 are controlled without emitting the light source 11, and the irradiation test and the dark test are repeated. Thus, a weather resistance test is performed.

  In the weather resistance tester 1 of the present embodiment, in particular, in the weather resistance test, in addition to the basic operation described above, various test modes described later (see FIG. 3 described later) are individually executed.

  In such a weather resistance test, the control unit 18 controls the irradiance to the sample 9 by controlling the radiation intensity of the light source 11 based on the light reception data obtained by the light receiver 16. As a result, the discharge power of the light source 11 is controlled so that the value of the light reception data substantially matches (preferably matches) the preset test condition value, and a stable radiation operation is ensured.

  The control unit 18 also controls the temperature in the test tank 10 and the temperature of the black panel thermometer 17 by controlling operations of a heater, a refrigerator, and the like (not shown). Such temperature control is performed using, for example, PID (Proportional-Integral-Derivative) control.

  Furthermore, the control unit 18 controls the relative humidity in the test tank 10 by controlling a humidity generator (not shown) based on the relative humidity calculated from the relationship between the dry bulb temperature and the wet bulb temperature. As a result, the humidity generator is controlled so that the relative humidity in the test chamber 10 substantially matches (desirably matches) a preset test condition value, and the set relative humidity is maintained.

(B. Operation during each test mode)
Next, with reference to FIG. 3 to FIG. 6 in addition to FIG. 1 and FIG. 2, operations in the various test modes described above in the weather resistance tester 1 will be described in detail.

  FIG. 3 schematically shows an example of a test mode in the weather resistance test. As shown in FIG. 3, in the example of the weather resistance test of the present embodiment, there are roughly two types of test modes, a high temperature test mode and a dew condensation test mode. Of these, as the dew condensation test mode, in this example, there are provided two types of test modes: dew condensation test mode 1 (front surface dew condensation) and dew condensation test mode 2 (rear surface dew condensation). That is, in this example of the weather resistance test, three types of test modes, that is, a high temperature test mode, a dew condensation test mode 1 and a dew condensation test mode 2 are provided.

  The dew condensation test mode 1 corresponds to a specific example of the “first dew condensation test mode” in the present invention. The dew condensation test mode 2 corresponds to a specific example of the “second dew condensation test mode” in the present invention.

  Here, the above-mentioned “high temperature test mode” is a weather resistance test performed in a state where the temperature in the sample holding box 14 is increased (high temperature state) as shown in FIG. Further, for example, when the sample 9 is the above-described glass for automobiles, the environmental condition assumed in the high temperature test mode includes, for example, a high temperature interior environment in the daytime. In the high temperature test mode, a black one is used as the sample holding box 14 as will be described in detail later.

  On the other hand, the above “condensation test mode” is a weather resistance test performed in a state where condensation is generated only on one of the front surface and the back surface of the sample 9.

  Specifically, in the above “condensation test mode 1”, as shown in FIG. 3, a state in which condensation is generated only on the surface of the sample 9 (the outer surface side in the sample holding box 14) (surface condensation state) It is a weather resistance test performed in For example, when the sample 9 is the glass for automobiles described above, the environmental conditions assumed in the dew condensation test mode 1 include, for example, a dew generation environment outside the vehicle at dawn. In the dew condensation test mode 1, although the details will be described later, a white one is used as the sample holding box 14.

  Further, the “condensation test mode 2” described above is performed in a state in which condensation is generated only on the back surface of the sample 9 (inner surface side in the sample holding box 14) (back surface condensation state) as shown in FIG. It is a weather resistance test. For example, when the sample 9 is the glass for automobiles described above, the environmental conditions assumed in the dew condensation test mode 2 are, for example, that a person gets on the automobile, the temperature and humidity in the vehicle rise, and the winter The environment in which the window glass is cooled by the outside air due to the traveling of the vehicle is mentioned. Specifically, for example, when the temperature inside the vehicle is 20 ° C. and the relative humidity is 70% RH, the dew point temperature is about 14 ° C., and the outdoor air temperature in winter is 10 ° C., the temperature of the window glass during driving is the dew point temperature. Will cause condensation to occur. In the dew condensation test mode 2 as well, although the details will be described later, a white one is used as the sample holding box 14.

  In this way, in the present embodiment, a dew condensation test (condensation test mode 1) that causes dew condensation only on the surface of the sample 9 and a dew condensation test (condensation test mode 2) that causes dew condensation only on the back surface of the sample 9 Both can be realized individually.

  Here, when the control unit 18 of the present embodiment performs a weather resistance test on the sample 9, the high temperature test mode and the dew condensation test mode (the dew condensation test mode 1 or the dew condensation test mode 2) are individually executed. As described above, operation control is performed. Below, the operation control by the control part 18 in each test mode is demonstrated in detail.

<High temperature test mode>
First, referring to FIG. 4 in addition to FIG. 3, the operation control in the “high temperature test mode” will be described. FIG. 4 is a schematic cross-sectional view showing an operation example of the sample holding box 14 in the high temperature test mode.

  In this high temperature test mode, as shown in FIG. 4, a sample holding box 14 having a black casing 140B (black box 14B) is used. Further, in the sample holding box 14 (black box 14B), the sample 9 is exposed with the surface Sf of the sample 9 out of the surface Sf and the back surface Sb of the sample 9 exposed to the outside (the light source 11 side in the test chamber 10). Is held. Specifically, as shown in FIG. 4, the upper end region and the lower end region of the sample 9 are held (fixed) by holding members 141a and 141b, respectively. The front surface Sf and the back surface Sb of the sample 9 correspond to specific examples of “first surface” and “second surface” in the present invention, respectively.

  In the high temperature test mode, as shown in FIG. 4, a temperature sensor 142 for detecting the temperature in the sample holding box 14 is arranged in the sample holding box 14. In addition, a heating blackboard 143 and a heat insulating sheet plate 144 are arranged on the side (back side) opposite to the holding surface of the sample 9 (front side located on the light source 11 side) in the sample holding box 14. Further, on the upper side surface and the lower side surface of the black casing 140B described above, a through air amount adjusting valve 145a for adjusting the amount of air (through air Ain, Aout) penetrating through the sample holding box 14, respectively. 145b is provided. The heating blackboard 143 corresponds to a specific example of “black member” in the present invention, and the heat insulating sheet plate 144 corresponds to a specific example of “heat insulating member” in the present invention.

  In this high temperature test mode, the temperature in the sample holding box 14 is adjusted using the black casing 140B in the black box 14B and the radiated light Lout (see FIG. 4) emitted from the light source 11 and transmitted through the sample 9. It is going to rise. In other words, the inside of the sample holding box 14 is set to a high temperature state using the black casing 140B and the radiation light Lout. Further, during this high temperature test mode, the opening / closing amounts (see arrows P1a and P1b in FIG. 4) of the through air amount adjustment valves 145a and 145b provided in the black casing 140B are adjusted (as appropriate by hand). The temperature in the sample holding box 14 is adjusted (adjustable). At this time, for example, based on the temperature detected by the temperature sensor 142, the opening / closing amounts of the through air amount adjusting valves 145a and 145b are adjusted.

<Condensation test mode>
Next, with reference to FIG. 5 and FIG. 6 in addition to FIG. 3, operation control in the “condensation test mode” (condensation test mode 1 and dew condensation test mode 2) will be described.

(Condensation test mode 1: Surface condensation)
First, FIG. 5 is a schematic cross-sectional view showing an operation example in the sample holding box 14 in the dew condensation test mode 1 (surface dew condensation).

  In the dew condensation test mode 1, as shown in FIG. 5, a sample holding box 14 having a white casing 140W (white box 14W) is used. Also in the sample holding box 14 (white box 14W), the sample 9 is exposed with the surface Sf of the sample 9 exposed to the outside (the light source 11 side in the test chamber 10), as in the case of the black box 14B described above. 9 is held. Specifically, as shown in FIG. 4, the upper end region and the lower end region of the sample 9 are held (fixed) by holding members 141a and 141b, respectively. Further, a dew condensation sensor 146 for detecting a dew condensation state, which will be described later, is disposed on the front surface Sf and the back surface Sb of the sample 9.

  Also in the dew condensation test mode 1, as shown in FIG. 5, a temperature sensor 142 for detecting the temperature in the sample holding box 14 is arranged in the sample holding box 14. In addition, a heat storage plate 147 is arranged on the back side in the sample holding box 14 instead of the heating blackboard 143 and the heat insulating sheet plate 144 in the high temperature test mode. The heat storage plate 147 corresponds to a specific example of “heat storage member” in the present invention.

  In the dew condensation test mode 1, the controller 18 controls the humidity in the test tank 10 (outside of the sample holding box 14) to increase, and a high humidity state is set. Further, as shown in FIG. 5, the temperature (temperature Tin) in the sample holding box 14 is changed to the test tank by ejecting the liquid W to the back side of the sample holding box 14 by the liquid ejecting mechanism 15 described above. The temperature falls below the temperature Tout in 10 (outside of the sample holding box 14) (Tin <Tout). That is, the control unit 18 controls the operation of ejecting the liquid W in the liquid ejecting mechanism 15 so as to satisfy such a temperature condition. The temperature Tout in the test tank 10 at this time is, for example, about 30 ° C., and the humidity in the test tank 10 (humidity in a high humidity state) is about relative humidity = 90% RH, and the temperature of the liquid W (For example, water temperature) is about 10 degreeC, for example. In the above case, since the dew point temperature is about 28 ° C., dew condensation occurs when the surface temperature of the sample is 28 ° C. or lower.

  In this way, in the dew condensation test mode 1, the control unit 18 raises the humidity in the test tank 10 (sets it to a high humidity state) and uses the ejection of the liquid W by the liquid ejection mechanism 15. Then, the temperature in the sample holding box 14 is lowered (set to a low temperature state). As a result, dew condensation occurs only on the surface Sf of the sample 9, as indicated by the symbol P2f in FIG.

  In the condensation test mode 1, the controller 18 also controls the condensation state that occurs only on the surface Sf of the sample 9 using the condensation sensor 146. Specifically, the control unit 18 controls the state of condensation by controlling the humidity and temperature in the test tank 10 and the temperature of the liquid W based on the measurement value of the condensation sensor 146, for example.

(Condensation test mode 2: backside condensation)
FIG. 6 is a schematic cross-sectional view showing an operation example in the sample holding box 14 in the dew condensation test mode 2 (back surface dew condensation).

  Also in the dew condensation test mode 2, as shown in FIG. 6, a sample holding box 14 having a white casing 140W (white box 14W) is used. Similarly to the case of the dew condensation test mode 1 described above, the sample 9 is held with the surface Sf of the sample 9 exposed to the outside (the light source 11 side in the test tank 10). Specifically, as shown in FIG. 6, the upper end region and the lower end region of the sample 9 are held (fixed) by holding members 141a and 141b, respectively. Further, as in the case of the dew condensation test mode 1, the dew condensation sensor 146 is disposed on the front surface Sf and the back surface Sb of the sample 9 as described above.

  Also in the dew condensation test mode 2, as shown in FIG. 6, the temperature sensor 142 for detecting the temperature in the sample holding box 14 is arranged in the sample holding box 14. Further, as in the case of the dew condensation test mode 1 described above, a heat storage plate 147 is disposed on the back side in the sample holding box 14.

  In the dew condensation test mode 2, the control unit 18 controls the temperature Tout in the test tank 10 to be lower than the temperature Tin in the sample holding box 14 (Tin> Tout) (set to a low temperature state). That is, the control unit 18 performs operation control so as to satisfy such a temperature condition. Specifically, in the dew condensation test mode 2, the sample holding box 14 is preliminarily sealed with liquid W ′ (water or the like) and sealed (see FIG. 6). The temperature Tout in the test tank 10 (outside of the sample holding box 14) is raised and then lowered (set in the order of high temperature state → low temperature state). Then, the temperature Tin in the sample holding box 14 becomes higher than the temperature Tout in the test tank 10 (Tin> Tout) by the heat storage action in the heat storage plate 147 built in the sample holding box 14. At this time, the liquid W ′ in the sample holding box 14 becomes saturated vapor near the stored temperature.

  In this way, in the dew condensation test mode 2, the control unit 18 uses the heat storage plate 147 to lower the temperature Tout in the test tank 10 below the temperature Tin in the sample holding box 14 (Tin> Tout). ) To control (set to low temperature state). As a result, the saturated vapor in the sample holding box 14 comes into contact with the back surface Sb of the sample 9 whose temperature has decreased, and dew condensation occurs only on the back surface Sb of the sample 9 as indicated by reference numeral P2b in FIG. Will occur.

  Note that, also in the dew condensation test mode 2, the control unit 18 controls the dew condensation state that occurs only on the back surface Sb of the sample 9 using the dew condensation sensor 146. Specifically, for example, the control unit 18 controls the temperature Tout in the test tank 10 based on the measurement value of the dew condensation sensor 146, thereby causing a temperature difference with the temperature Tin in the sample holding box 14, Control the state of condensation.

(C. Action / effect)
As described above, in the weather resistance test machine 1 of the present embodiment, the high temperature test mode and the dew condensation test mode (the dew condensation test mode 1 or the dew condensation test mode 2) are separately performed during the weather resistance test. The operation control is performed. Thereby, in this Embodiment, the weather resistance test under various test conditions is implement | achieved. Particularly in this example, both the dew condensation test (condensation test mode 1) for generating dew condensation only on the surface of the sample 9 and the dew condensation test (condensation test mode 2) for generating dew condensation only on the back surface of the sample 9 are provided. Since these are realized individually, it is possible to realize a weather resistance test under various test conditions.

  Here, for example, in the above-described automotive glass, depending on the usage environment (temperature and humidity inside and outside the car), condensation occurs on the front and back surfaces, and the temperature difference between the inside and outside of the car increases. Therefore, it is necessary to confirm their influence. In the weather resistance testing machine 1 of the present embodiment, the various test modes described above are provided, so that it is possible to realize a weather resistance test while reproducing various environmental conditions for confirming these effects. It becomes.

  In the present embodiment, in the high temperature test mode, the sample holding box 14 (black box 14B) having the black casing 140B is used, and the sample 9 is emitted from the black casing 140B and the light source 11 and passes through the sample 9. Using the emitted light Lout, the temperature in the sample holding box 14 is increased. As described above, the temperature in the sample holding box 14 is likely to rise using the black casing 140B and the radiation light Lout (can be efficiently set to a high temperature state), so that the convenience in executing the high temperature test mode is improved. To do.

  Further, in this high temperature test mode, a heating blackboard 143 and a heat insulating sheet plate 144 are respectively arranged on the side opposite to the holding surface (front side) of the sample 9 in the sample holding box 14. This makes it easier for the temperature in the sample holding box 14 to rise using the warming blackboard 143 (can be set to a high temperature state more efficiently). Further, by using the heat insulating sheet plate 144, heat radiation from the sample holding box 14 is suppressed, and a high temperature state is easily maintained. From these things, in this Embodiment, the convenience at the time of performing high temperature test mode further improves.

  In addition, during this high temperature test mode, the temperature in the sample holding box 14 is adjusted by adjusting the opening / closing amounts of the through air amount adjustment valves 145a, 145b provided in the black casing 140B. ing. Thereby, for example, as shown in FIG. 2, when a plurality of sample holding boxes 14 are provided in the test tank 10, the temperature in each sample holding box 14 can be set individually. As a result, the convenience in executing the high temperature test mode is further improved.

  In the present embodiment, in the dew condensation test mode 1 and the dew condensation test mode 2, the sample holding box 14 (white box 14W) having the white casing 140W in which the heat storage plate 147 is built is used. As described above, since the white housing 140W and the heat storage plate 147 are built in, the white housing is used even when the sample holding box 14 is irradiated with, for example, external light (for example, radiated light Lout from the light source 11). Since it is 140 W, the temperature (temperature Tin) in the sample holding box 14 is unlikely to rise (it is easy to maintain a low temperature state). Further, since the heat storage plate 147 is built in, the temperature in the sample holding box 14 can be easily maintained at the low temperature state or the high temperature state even when the temperature in the test chamber 10 changes. Furthermore, since it is not necessary to install a cooling device, a heating device, or the like in the sample holding box 14, the structure of the sample holding box 14 becomes simple and the cost can be reduced. Incidentally, for example, as shown in FIGS. 1 and 2, when the sample holding box 14 rotates in the test tank 10, the liquid W is intermittently ejected from the liquid ejecting mechanism 15 described above. Since the heat storage plate 147 is provided in the sample holding box 14, even in such a case, temperature fluctuations in the sample holding box 14 can be suppressed (it is easy to maintain a low temperature state).

  Further, in the condensation test mode 1 and the condensation test mode 2, the control unit 18 uses the condensation sensor 146 to indicate the state of condensation that occurs only on one surface (the front surface Sf or the back surface Sb) of the sample 9. It comes to control. Specifically, the control unit 18 controls the state of condensation by controlling the humidity and temperature in the test tank 10 and the temperature of the liquid W, for example. Thereby, since the state of the dew condensation generated on the sample 9 can be adjusted with high accuracy, the reproducibility in the dew condensation test mode is improved.

  As described above, in this embodiment, since the operation control during the weather resistance test is performed so that both the high-temperature test mode and the dew condensation test mode are executed individually, various test conditions can be obtained. It is possible to realize a weather resistance test at Therefore, it is possible to improve convenience when performing the weather resistance test.
