Xenon Lamp Aging Test Chamber

XD-WAT-Ci3000 Xenon Lamp Aging Test Chamber (Xenon arc Lamp Aging and Weathering Test Chamber) operates on the core principle of “simulating nature + accelerating aging.” Equipped with a xenon arc lamp capable of reproducing the full spectrum of sunlight (with a spectrum over 90% similarity to natural light), it accurately reproduces the destructive light waves such as ultraviolet and visible light in outdoor sunlight. Combined with temperature control, spraying, and humidity adjustment modules, it constructs an alternating cyclical environment of “sunlight – high temperature – spraying – low temperature condensation,” fully simulating the three core factors that cause material aging: sunlight, temperature, and humidity. By enhancing the efficiency of key aging conditions, it compresses aging phenomena that would take months or even years outdoors to occur into days or weeks, providing support for rapidly obtaining material weathering performance data.

XD-WAT-Ci3000 Xenon arc Lamp Aging and Weathering Test Chamber covers testing needs in multiple fields. It can support the material research and development process, such as helping researchers screen new material formulations for coatings, plastics, and textiles, and optimize product weather resistance by comparing the performance of different formulations after aging (such as color difference and strength changes). It can also be used for industrial product quality inspection, conducting pre-shipment weathering resistance tests on aluminum composite panels, photovoltaic module backsheets, and building waterproofing materials according to industry standards to ensure that products meet market access requirements. At the same time, it can also serve the automotive industry, simulating the usage environment of vehicles under different climatic scenarios such as high temperature exposure and rainy and humid conditions, testing the anti-aging and anti-fading capabilities of automotive safety glass, interior parts (such as dashboard fabric), and exterior parts (such as bumpers and paint). In addition, it also provides professional equipment support for research institutes to study the aging mechanism of materials and for third-party testing agencies to undertake weathering testing business in multiple industries.

Standards:

Note: Different standards have slightly different requirements for xenon lamp aging tests. We recommend that you confirm with LISUN engineers which standards each LISUN xenon lamp aging chamber model meets, so that they can accurately match your testing needs.

Part 1 – Specifications (Water-Cooled Xenon Lamp Test Chamber):

Part 2 – Specifications (Air-Cooled Xenon Lamp Test Chamber):

Recommendation 1: LISUN offers a variety of external filters (XD-FILTER-OUT) and internal/external filter combinations (XD-FILTER-IN) (see image on the right). These are suitable for the XD-WAT series (water-cooled) and XD-AIR series (air-cooled) xenon arc weathering chambers and are also compatible with mainstream xenon arc chambers from brands such as ATLAS and Q-LAB, meeting diverse spectral filtering requirements for weathering tests.

Recommendation 2: XD-WAT-LAMP xenon lamp series includes various water-cooled and air-cooled models (see image above, right). Specifically designed for xenon-arc weathering and aging tests, these lamps produce a spectral output that simulates natural sunlight, meeting the requirements for accelerated photo-aging tests across a wide range of materials. In addition to being suitable for LISUN’s XD-WAT (water-cooled) and XD-AIR (air-cooled) xenon aging chambers, these lamps are also compatible with mainstream xenon aging chamber models from ATLAS and Q-LAB.

Recommendation 2: XD-PURE-800G commercial water purifier is a commercial reverse osmosis water purification equipment specially designed for water-cooled and air-cooled xenon lamp aging test chambers. It is equipped with a sand filter, a carbon filter, and a resin tank to complete pre-treatment, effectively filtering out impurities such as sediment, residual chlorine, scale, and bacteria, and supplying qualified pure water sources for the xenon lamp aging test chamber. The equipment adopts a five-stage filtration process, and the RO reverse osmosis filtration accuracy can reach 0.0001 micron, producing stable and qualified pure water to avoid water impurities causing scaling and blockage of xenon lamp tubes and cavity pipes.

Commercial Water Purifier

1. Sample Preparation: Cut representative samples according to the test standards (e.g., plastic or paint specimens sized to fit the test frame). Test initial color difference using LISUN HSCD-860 Portable Spectrophotometer (High Accuracy Reflectance), initial gloss using LISUN AGM-500 Gloss Meter with Single Angle, and initial tensile strength using LISUN PULL-500KG Double Columns Tensile Testing Machine. Record the data as a baseline. Samples must be properly packaged to prevent contamination or damage during handling and ensure consistent initial condition.

2. Equipment Inspection and Preparation: Inspect the xenon lamp aging chamber’s exterior and component connections. Verify that the xenon lamp life has not exceeded the specified operating time, that the cooling system and water spray system are functioning properly, and that the water tank is adequate and meets water quality standards (e.g., conductivity<5μs/cm). Calibrate key parameters: Use standard instruments to calibrate the irradiance intensity (e.g., 340nm band) or the air temperature sensor to ensure that the error is within the standard tolerance (±2°C).

3. Test Condition Setup: Irradiance: Set a target value (e.g., 0.55 W/m² @ 340 nm or 1.10 W/m² @ 340 nm) and precisely adjust it using the device control system. Temperature: Set the light phase to 50–89°C (e.g., 63°C ± 3°C), and the dark phase to 50°C ± 2°C (according to standard requirements). Humidity: Set a cycling humidity as needed (e.g., 30%–95% RH) to simulate varying humidity conditions.

4. Sample Placement: Secure the sample to the sample test rack within the chamber, ensuring that the sample faces the xenon lamp light source and that the sample is spaced ≥ 10 mm apart to ensure uniform illumination and temperature. Cover any unplaced sample areas with a blackboard to minimize fluctuations in the chamber environment.

5. Test Run: Close the chamber door, start the equipment, and wait 30 minutes to confirm that the irradiance, temperature, humidity, and other parameters have stabilized at the set values. Start the timer. During operation, regularly check the equipment status. Observe and photograph changes in the sample’s appearance every 250 hours or at standard intervals. Avoid frequent door openings during operation (if door opening is necessary, pause the timer and restart it after parameters are restored).

6. Intermediate and Final Testing: During or after the test (if the specified number of cycles has been reached) remove the sample and place it in a standard environment (23°C ± 2°C, 50% ± 5% RH) for a period of time (e.g., 4 hours) for condition adjustment. Again, test color difference with HSCD-860 Portable Spectrophotometer (High Accuracy Reflectance), gloss with AGM-500 Gloss Meter with Single Angle, and tensile strength with LISUN PULL-500KG Double Columns Tensile Testing Machine to track aging changes and compare to initial values to assess the extent of aging.

7. Result Evaluation: Appearance Assessment: Observe the sample for signs of fading, chalking, cracking, bubbling, etc., and quantify appearance changes based on LISUN instrument test data. Performance evaluation: Analyze the attenuation of mechanical properties (such as tensile strength and elongation at break) and chemical properties (such as molecular weight change) to determine whether the material’s weather resistance level meets the standard requirements.
