Working principle
The core component of the xenon lamp aging test chamber is the xenon lamp, which can emit light that is very close to the solar spectrum, including ultraviolet (UV), visible light, and infrared (IR). By controlling parameters such as light intensity, temperature, humidity, and rainfall, the test chamber can simulate various natural environmental conditions, thereby accelerating the aging process of materials.
major function
oneSimulated sunlight: The spectrum emitted by xenon lamps is very close to the solar spectrum, and can simulate the effects of ultraviolet, visible, and infrared light.
twoTemperature control: The temperature inside the test chamber can be controlled within a certain range, usually from -40 to 150 (the specific range depends on the equipment model).
threeHumidity control: The humidity inside the test chamber can be controlled between 20% and 98%.
fourRainfall simulation: Some models of xenon lamp aging test chambers are equipped with water spray systems, which can simulate the impact of rainwater on materials.
fiveLight intensity control: The light intensity can be adjusted to meet different testing needs.
The testing cycle of a xenon lamp aging test chamber usually depends on multiple factors, including testing standards, material types, environmental conditions, and testing objectives. Here are some common testing cycles and related information:
1. Testing standards:
Different industries and materials have different testing standards. For example, standards such as GB/T16585-1996, GB14522-93, and GB/T16422.3-97 have specific requirements for testing cycles
Some common international standards such as ASTM D2565, ISO 4892-2, AATCC 169 (1), etc. also require testing cycles.
2. Testing cycle range:
Short term testing: Some testing cycles are relatively short, possibly between a few days to a few weeks. For example, some rapid aging tests may only take a few days.
Mid term testing: The common testing cycle is around 500 hours, which is equivalent to one year in real time.
Long term testing: For materials that require evaluation of long-term weather resistance, the testing cycle may take several months or even a year. For example, the Q-Sun light source testing cycle is generally between 1 and 3 months, while the Atlas and Suntest testing cycles can last up to 6 months to 1 year.

Q: What materials can be tested using this xenon weathering chamber?
A: The chamber is suitable for a wide variety of specimens, including plastics, textiles, rubber, paints, and coatings. It is specifically designed to assess deterioration, color fading, and performance changes caused by long-term exposure to sunlight, temperature, and humidity.
Q: When should I use the test chamber's programmable features?
A: Use the programmable cycles and automatic spray/light controls when you need to simulate specific environmental conditions or conduct repetitive, standardized tests. The microprocessor-based touch control panel allows for precise scheduling and adjustment of test parameters to meet different experimental requirements.
Q: Where can data from test cycles be accessed or exported?
A: Test data can be accessed in real-time via the digital LCD touch screen and exported through RS232 or USB interfaces. This ensures convenient data management and integration with your existing research or quality control systems.
Q: What is the process for conducting a test in this weathering chamber?
A: First, place up to 24 specimens (150 mm x 70 mm each) in the chamber. Set the desired program parameters for test cycles, temperature (up to 70C), humidity, wind speed, and spray using the touch screen. Once started, the system automatically controls light, spray, and environmental conditions, with real-time monitoring and safety features in place.
Q: How does the chamber ensure safety during operation?
A: Safety is ensured through multiple features, including overload, overheat, water and air shortage alarms, a door interlock system, and leakage protector. These safeguards protect both the operator and specimens, and prevent chamber malfunction during unattended testing.
