When testing materials for outdoor durability, accurate simulation of sunlight, heat, and moisture is critical. A Xenon test chamber replicates natural sunlight using full-spectrum xenon arc lamps, delivering repeatable, standards-compliant accelerated aging results for plastics, coatings, films, and automotive components.
LIB's Xenon Arc Weatherometer meets international standards, including ASTM G151, D6695, G155, ISO 11341, and D7869, ensuring reliable testing and traceable data.

Working Principle of Xenon Test Chambers for Realistic Sunlight Simulation
Xenon test chambers use water-cooled xenon arc lamps to mimic natural sunlight across the 280–800 nm spectrum, including UV, visible, and infrared radiation. Key operational features include:
Light Control: 4500 W xenon lamps with real-time radiometer feedback deliver uniform irradiance across up to 42 flat or custom samples. Optional daylight, window-glass, and extended UV filters allow precise simulation of different sunlight conditions.
xenon lamp and filters
Temperature Control: Black Panel Temperature (BPT) is maintained between 35–85 °C (±2 °C) and Chamber Air Temperature (CAT) ranges from 35–50 °C, ensuring consistent degradation rates.
Humidity & Spray Cycles: Adjustable 30–98 % RH with automated filtered water sprays simulating dew and rain. A closed-loop water recovery system saves up to 80 % of water.

Rotating Sample Holders (customizable): Flat-panel holders accommodate large or irregular samples without compromising uniformity.
This system guarantees repeatable, standards-compliant results for outdoor-exposed materials.

Exceptional Capability of Xenon Test Chamber for Accelerated Aging to Evaluate Coatings According to ASTM G151
ASTM G151 specifies a method for accelerated aging exposure testing of nonmetallic materials using laboratory light sources, emphasizing that laboratory test conditions should replicate the aging trends of materials in actual outdoor environments as closely as possible. The standard explicitly states that laboratory testing is primarily used to compare the relative durability of materials and consistency between batches, and cannot directly substitute for real-world outdoor service life evaluation.
The LIB Xenon Arc Test Chamber strictly adheres to ASTM G151-19, enabling precise control of light intensity, temperature, humidity, and spray cycles to ensure stable, repeatable, and comparable material test results. Based on the standard's typical exposure conditions, the LIB test chamber achieves the following control parameters:
Light Intensity and Wavelength Control: Provides irradiance ranging from 0.30–1.10 W/m²·nm, covering wavelengths from 340–420 nm. Supports Daylight and Window Glass filters to simulate various daylight conditions.
Black Panel Temperature and Humidity Cycling: Maintains black panel temperatures from 63–77°C, paired with relative humidity cycles from 35–70%.
Flexible Exposure Cycles: For example, 102-minute illumination + 18-minute spray cycle, or 1.5-hour illumination + 0.5-hour spray cycle.
Configurable Dark Periods and Humidity Variations: Such as 6 hours dark + 95% RH, or 1 hour dark + 90% RH, precisely simulating real-world environments.
The LIB Xenon Arc Test Chamber precisely controls light intensity, wavelength, black panel temperature, humidity, and spray cycles to fully comply with ASTM G151-19 standards. It delivers reliable, repeatable, and customizable laboratory solutions for accelerated aging testing of coatings, plastics, and automotive materials, enabling R&D and quality control teams to conduct efficient, scientific durability evaluations.
LIB Xenon Test Chamber and UV Test Chamber Available for Selection
Choosing between a Xenon Arc Chamber and a UV Test Chamber depends on the material and testing purpose:
 |
 |
|
|---|---|---|
| Feature | Xenon Arc Chamber | UV Test Chamber |
| Light Spectrum | Full 280–800 nm | UV-focused 280–400 nm |
| Applications | Outdoor materials, automotive, building products | Indoor plastics, packaging, coatings |
| Environmental Simulation | Light, temperature, humidity, and spray cycles | UV irradiation with optional humidity or condensation |
Recommendation: Use a Xenon Arc Chamber for full sunlight simulation, such as automotive parts, outdoor coatings, and plastics. Choose a UV Chamber for UV-only degradation or preliminary R&D testing.
