Xenon Lamp Aging Test Chamber

The XD-150LS Xenon Lamp Aging Test Chamber (also knows as Xenon Test Chamber and Xenon Arc Weathering Test Chamber)  utilizes the core principle of “natural aging + accelerated aging.” It was equipped with a xenon arc lamp that reproduces the full spectrum of sunlight (combined with a filter system, the spectrum is over 90% similar to natural light), it accurately reproduces the damaging wavelengths of outdoor sunlight, including ultraviolet and visible light. Combined with temperature control, spray, and humidity regulation modules, it creates an alternating cycle of “light exposure – high temperature – spray – low temperature condensation,” fully simulating the three core factors that contribute to material aging: sunlight, temperature, and humidity. By enhancing the efficiency of key aging conditions, it compresses aging phenomena that would typically occur outdoors over months or even years into days or weeks, enabling rapid acquisition of material weathering performance data.

The XD-150LS Xenon Arc Weathering Test Chamber can provide support for material research and development, for example to help R&D personnel screen the formulas of new materials such as coatings, plastics, textiles and optimize product weather resistance by comparing the performance of materials with different formulas after aging (such as color difference and strength change); it can also be used for industrial product quality inspection and conduct pre-delivery weather resistance testing on aluminum-plastic panels, photovoltaic module backplanes, building waterproof materials, etc. in accordance with industry standards to ensure that the products meet market access requirements; it can also serve the automotive industry, simulating the use environment of vehicles in different climate scenarios such as high temperature, exposure, rain and humidity and testing the anti-aging and anti-fading capabilities of automotive safety glass, interior trims (such as dashboard fabrics) and exterior trims (such as bumpers and car paint). In addition, it also provides professional equipment support for scientific research institutes to study material aging mechanisms and for third-party testing agencies to undertake weather resistance testing business in multiple industries.

Reference 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.

Specifications:

Note: The corresponding quantity and power of xenon lamps can be customized according to the customer’s requirements!

Test Procedures:
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.
