Its 4500 W water-cooled xenon lamp maintains 35–150 W/m² stable irradiance with ±0.5% precision, ensuring repeatable exposure across long test cycles. The controlled environment supports BPT 35–85 °C, air temperature ambient–100 °C, and 50–98%RH humidity, enabling complex degradation of polymers, coatings, automotive trims, and outdoor materials.

A redesigned system architecture integrates window/daylight/extended-UV filters, programmable wet–dry and spray cycles, and a smart PID touchscreen controller with multi-language UI, remote monitoring, and full data export.

Purpose-built for G151-compliant weathering, it helps manufacturers predict color fade, cracking, gloss loss, and mechanical decay with fast, traceable results.

Key Advantages of LIB Industry G151 Xenon Arc Weathering Test Apparatus

True Solar Replication for Fast, Realistic Aging
Its full-spectrum UV–VIS–IR output recreates outdoor sunlight with laboratory stability, combined with ambient–100 °C thermal loading and a built-in condensation cycle that simulates dawn moisture and surface cooling. A long-life xenon lamp (>1600 h) ensures consistent exposure throughout extended test programs.

High-Precision Exposure Reliability
A redesigned optical layout ensures exceptional irradiance uniformity across every test zone, while synchronized control of spectrum, temperature, and humidity stabilizes long-duration weathering. Cross-chamber repeatability remains tight, delivering certification-ready data for quality comparison and production validation.

Wide Material Compatibility for G151 Weathering
The system targets real-world degradation of automotive interiors/exteriors, outdoor plastics and polymers, photovoltaic materials, coated metal panels, construction materials, and packaging inks-covering the full spectrum of UV/visible aging, gloss loss, and structural decay required by G151 workflows.

Flexible Architecture for Complex Test Demands
Engineered for scalability, it supports expanded sample capacity, adjustable spray pressure and nozzle configurations, and tailored spectral emphasis in UV or IR ranges to match product-specific failure modes.

Discover ASTM G151 Xenon Arc Weathering Test Apparatus

1. Is this equipment suitable for evaluating long-term coating durability?

Yes. LIB industry builds the G151 apparatus specifically for coatings, automotive paints, powder coatings, and UV-cured layers. For corrosion-related studies, LIB industry can additionally provide salt spray chambers for combined aging workflows.

2. Can the apparatus test temperature-sensitive or oversized samples?

Yes. Flexible sample frames and optional extended-height workrooms allow unusual geometries and low-mass materials to be exposed without overheating.

3. How often are filters and lamps serviced?

Optical filters should be checked and cleaned every 3–6 months, while xenon lamps usually require replacement after 1600 hours depending on irradiance level.
