ASTM G154 UV Weather Tester UV Accelerated Ageing Test Chamber
1.Use
The UV Accelerated weathering test chamber stimulates dew and rain with consideration for humidity and/or water spray equipped with a fluorescent UV lamp which can completely simulate the UV spectra of sunlight, exposes materials to alternating cycles of UV light and moisture at controlled, elevated temperatures. It's most widely used weathering tester to test types of damages include color change, gloss loss, chalking, cracking, crazing, hazing, blistering, strength loss and oxidation. The source adopts 8 pieces of UV lamps of 40W as the light source. The lamps are distributed on the two sides of machine, 4 pieces for each side (UVA-340 and UVB-313 optional), 8 pieces in total .

| 1.Structure & Material | ||
| Structure: 1.The middle of the machine is the working chamber, the water system located at the bottom of machine, its top is the control cabinet and control panel. Open the door from front direction. The bottom of the chamber with high-quality PU activity wheel that can be fixed, users can move it according to their requirements positioning. 2.Single cycling system for air flue in the box, there's one inlet axis weeding machine which improves the flow amount of air, the heating ability and the whole temperature uniformity in the test machine. Water source and consumption: Tap water or distilled water for 8liters per day. 3.Heating method is to heat liner water tank with fast heating speed and high temperature uniformity. Material: 4.Inner box: high grade stainless steel plate 5.Outer box: stainless steel plate SUS304 or stoving varnish for option. |
||
| 1.Spray System | ||
| 1.Using the manual control function of the controller, to observe the spray condition in the open-door state, so as to adjust or replace the nozzle. 2.The machine is equipped with a sprinkler, the sprinkler simulates the temperature upheaval and rain erosion during the rain, with a total of several nozzles, sprayed evenly. The spray time is set by the customer. 3.Inner water level is with automatic water replenishing. |
||
| 1.Light source system | ||
| Types of light source (simulate the sunlight) Light source: 4 imported UV fluorescent lamps (ATLAS) with rated power of 40W, UVA-340 and UVB-313 light source for users to choose. Like other lamps, the aging of the QUV tube causes the lamp output to drop, and the QUV without the Irradiance meter control system uses the rotational position method to compensate. This system can be used for many application standards, but it has inherent limitations. This method of changing position does not compensate for the effects of different batches of lamps or the surrounding environment.  Fig. - Lamp replacement method. 2.UVA-340: A wavelength that emits sunlight from 365 nm to 295 nm, and its radiation peak is at 340 nm. UVA-340 is especially useful for control tests in different tests, with the best simulation of sunlight in the short-wave UV range. 3.UVB-313: The wavelength range is between 280 nm and 315 nm. UVB-313 ages faster than UVA-340 lamps, but their shorter wavelengths than the sun cutoff point can have unrealistic results for many materials. |
||
| 2.UV Cycle Temperature control | ||
| The components of the UV cycle system include a blower, air heater, air distribution system, and blackboard temperature sensor. 1.Blower: Installed in the lower tank air duct of the equipment, the blower is continuously operated throughout the UV cycle. 2.Air heater: Installed in the air duct above the blower to heat the air blown by the blower when needed. 3.Air distribution system: The air blown by the blower enters the test chamber through the air duct, and then the air guide to the entire chamber. |
