When you need repeatable, standards-aligned xenon arc exposure, you need a chamber that reproduces sunlight, heat, and moisture reliably - and documents it.
LIB's xenon arc weatherometer is engineered around ASTM G155-21 requirements to deliver measurable, reproducible outdoor-simulation results for plastics, coatings, films, and components.

【How Can LIB's Xenon Arc Weatherometer Deliver Realistic Sunlight Exposure under ASTM G155?】
When testing plastics, coatings, or automotive parts for outdoor durability, the core requirement is to mimic real sunlight with precision. ASTM G155-21 specifies the use of xenon arc lamps with different daylight filters, including recent updates that highlight chamber air temperature (CAT) settings.
LIB's xenon arc weathering chambers employ a 4500 W water-cooled xenon lamp that delivers the full spectrum from 280 nm to 800 nm, covering UV, visible, and infrared radiation. This ensures your samples receive the same energy profile as actual sunlight.
- Multiple Filter Options: Daylight, window-glass, and extended UV filters for different application needs.
- Uniform Exposure: A rotating sample rack supports up to 42 specimens, guaranteeing consistent irradiance distribution.
- Realistic Weather Cycles: Light/dark phases, humidity, and spray cycles can be programmed to replicate dew, rain, or long summer days.
By combining sunlight simulation with moisture and temperature cycles, LIB chambers reproduce years of outdoor exposure in just weeks.

【How Can LIB's Arc Weatherometer Achieve Precise Light, Temperature, and Humidity Control per ASTM G155?】
 |
-Sample holder: Adjustable speed, 1r/min
-Irradiation Source: 1 piece of 4500w water-cooled xenon arc lamp with inner quartz and outer borosilicate filter
-Bandwidth Measurement: 300~400nm
-Irradiance Range:150W/㎡
-Chamber Temperature Range: -40～ 100 ℃ ±2℃
-Black Panel Temperature: BPT 35 ～ 85 ℃ ±2℃
-Humidity Range: 30% ~ 98% RH
-Interior Material-SUS304 stainless steel -Exterior Material-A3 Steel plate with protective coating |
ASTM G155-21 places new emphasis on Chamber Air Temperature (CAT), along with Black Panel Temperature (BPT/BST), because even a 5–10 °C difference in CAT can significantly affect sample surface temperatures-especially for light-colored or transparent plastics. LIB chambers integrate advanced sensors and PID controllers to deliver unmatched precision:
- Light Control: Full-spectrum radiometer for real-time irradiance monitoring, maintaining stability within ± 5 %.
- Temperature Control: BPT maintained at 63 °C, CAT adjustable from 35 °C to 50 °C, ensuring reproducible degradation rates across labs.
- Humidity Control: 20 %–98 % RH with stability of ± 2.5 % RH.
- Spray & Condensation: Automatic deionized water system with closed-loop recycling reduces water use by up to 80 %.
