How UV and Xenon Arc Chambers Recreate Real Outdoor Conditions
UV Weathering Test Chambers
UV Weathering Test Chambers use fluorescent UV lamps (commonly UVA-340 or UVB-313) to reproduce the short-wave ultraviolet spectrum of natural sunlight. They focus on accelerated testing of surface degradation, such as color fading, gloss loss, or cracking.
Typical Standards: ASTM G154, ISO 4892-3
Common Conditions: 35 ～ 80 ℃ black panel temperature,≥95% RH relative humidity, alternating UV and condensation cycles
Ideal For: Coatings, plastics, paints, rubber, and polymer materials
Xenon Arc Chambers
In contrast, Xenon Arc Chambers use a xenon arc lamp that closely simulates the full solar spectrum, including UV, visible, and infrared light. This makes them ideal for evaluating both color and mechanical performance over long-term exposure.
Typical Standards: ASTM G155, ISO 4892-2, SAE J2527
Common Parameters: Irradiance 0.35–1.10 W/m² (at 340 nm), temperature Ambient ～ 100 ℃ ±2℃, humidity 50% ~ 98% RH
Ideal For: Automotive components, textiles, packaging, and outdoor construction materials
Technical Comparison: Choosing the Best Chamber for Your Material Durability Tests
| Feature | UV Weathering Chamber | Xenon Arc Chamber |
| Light Source | Fluorescent UV lamp | Xenon arc lamp |
| Spectrum Coverage | UV range (295–400 nm) | Full spectrum (280–800 nm) |
| Energy Cost | Low | High |
| Application Focus | Surface weathering | Full-spectrum light aging |
| Typical Test Duration | 300–1000 hours | 500–2000 hours |
If your product mainly suffers UV-induced surface damage, the UV chamber offers an efficient and economical option. However, for comprehensive sunlight simulation and color stability assessment, a xenon arc test chamber provides more realistic results.
