When testing materials for outdoor durability, sunlight, heat, and moisture exposure must be replicated accurately, repeatedly, and in compliance with international standards.
LIB's Xenon Arc Weatherometer delivers precise, accelerated aging results for plastics, coatings, films, and automotive components, while fully complying with international standards including ASTM G151, D6695, G155, ISO 11341, and D7869.

【Achieving Precise Control of Light, Temperature, and Humidity with LIB's Arc Weatherometer Accelerated Aging Chamber per ASTM G151】
ASTM G151 specifies accelerated weathering tests using xenon arc lamps to simulate natural sunlight. Key requirements include:
- Full-spectrum radiation from 280–800 nm, covering UV, visible, and infrared.
- Accurate Black Panel Temperature (BPT) and Chamber Air Temperature (CAT) control to prevent deviation in sample surface temperatures.
- Controlled humidity and spray cycles to mimic dew, rain, and other environmental conditions.
LIB's Xenon Arc Weatherometer meets these requirements through:
Light Control: A 4500 W water-cooled xenon lamp delivers stable full-spectrum irradiance, measured in real time with a radiometer. Exposure uniformity is achieved across up to 42 flat or custom-sized samples simultaneously. Users can calculate irradiance for each sample position to ensure consistent energy absorption. . Multiple filter options-daylight filter, window-glass filter, and extended UV filter-allow precise simulation of different sunlight conditions.

Temperature Control: BPT can be precisely maintained between 35–85 °C (±2 °C), while CAT ranges from 35–50 °C, minimizing variability in degradation rates.

Humidity & Spray Control: Adjustable 30–98 % RH, with automated filtered water spray cycles replicating outdoor moisture patterns. Closed-loop water recovery saves up to 80 % water.
Custom Sample Holder: Unlike rotating racks, flat panel holders can be customized for larger samples or irregular shapes, providing flexibility without sacrificing measurement accuracy.
This combination ensures repeatable, standards-compliant results for plastics, coatings, films, and components.
【Customizable Solutions for LIB Xenon Arc Accelerated Aging Chamber】
LIB provides a fully adaptable platform to meet diverse testing requirements:

Spray System Flexibility: Options for internal, external, or dual-direction water spray, allowing simulation of rain, condensation, or combined environmental effects.
Xenon Lamp Enhancements: Optional hydrogen peroxide injection into the lamp beam can accelerate oxidative aging for coatings and polymers.
Cycle Programming: Up to 120 programs with 100 steps each, including light exposure, water spray, and dark phases. PID controllers maintain precise irradiance, temperature, and humidity profiles.

These features make LIB chambers suitable for R&D, quality control, and regulatory compliance in coatings, automotive, and plastics industries.
【Xenon Arc Accelerated Aging Chamber vs. UV Test Chamber: Choose the Optimal Solution】
Selecting the right light fastness testing system depends on material type and application:
|
|
|
|
|---|---|---|
| Feature | Xenon Arc Chamber | UV Test Chamber |
| Light Spectrum | Full-spectrum 280–800 nm | UV-focused 300–400 nm |
| Applications | Outdoor-exposed materials, automotive, building products | Indoor plastics, packaging, coatings |
| Environmental Simulation | Light, temperature, humidity, and spray cycles | UV irradiation with optional humidity or condensation cycles |
Recommendation: Choose a Xenon Arc Chamber when full sunlight simulation is critical, such as automotive parts, outdoor coatings, and plastics. Opt for a UV Chamber if UV-only degradation or early-stage R&D is the main concern.
