Introduction to Xenon Lamp Accelerated Aging Testing
Accelerated aging testing is a critical methodology for evaluating the long-term durability of materials and components under controlled environmental stressors. Among the most effective tools for this purpose is the Xenon Lamp Accelerated Aging Chamber, which simulates sunlight, temperature fluctuations, and humidity to predict product lifespan. The LISUN XD-150LS exemplifies this technology, offering precise spectral irradiance control, temperature regulation, and humidity simulation for industries ranging from automotive electronics to aerospace components.
Fundamental Principles of Xenon Lamp Aging Simulation
Xenon arc lamps replicate the full solar spectrum, including ultraviolet (UV), visible, and infrared (IR) wavelengths, making them superior to other artificial light sources for aging tests. The XD-150LS employs a filtered xenon lamp system that adheres to international standards such as ISO 4892-2, ASTM G155, and IEC 60068-2-5, ensuring accurate reproduction of natural sunlight effects.
Key mechanisms include:
- Photodegradation: UV radiation breaks down polymer chains, leading to fading, brittleness, or cracking.
- Thermal Stress: Cyclic heating and cooling induce material expansion and contraction, accelerating fatigue.
- Moisture Exposure: Humidity exacerbates corrosion, delamination, and electrical insulation failure.
