In the competitive landscape of material science, durability is more than a feature—it is a safeguard. From high-performance automotive polymers to protective infrastructure coatings, UV radiation is the ultimate judge of long-term reliability.
ASTM G154 and ISO 4892-3 define the international standard for accelerated weathering. They set the precise conditions under which materials must demonstrate resilience. At LIB Industry, our UV Test Chambers act as a "Time Machine", letting you simulate years of outdoor exposure in just hundreds of hours.
Not all chambers are created equal. While many claim compliance, LIB Industry delivers Precision Margin—turning standard requirements into verifiable, repeatable data.
| Technical Parameter | ISO 4892-3 / ASTM G154 Requirement | LIB UV Series Performance |
|---|---|---|
| Irradiance Range | 0.35–1.55 W/m² (at 340 nm) | ±0.02 W/m² Ultra-stable Control |
| Black Panel Temp (BPT) | 30–90 °C | ±0.3 °C PID Self-tuning Accuracy |
| Light Source | Fluorescent UV Lamps | USA-made QUV UVA-340 / UVB-313 / UVB-351 (up to 5000 h) |
| Water Spray Pressure | Standard Nozzle Flow | 0.1–0.3 MPa Adjustable Precision |
Key Advantage: Every element—from lamp irradiance to black panel temperature—is designed to maintain constant and repeatable stress, ensuring trustworthy accelerated weathering data.
To survive the audit of time, materials must endure UV, heat, and moisture simultaneously. LIB UV Chambers integrate three core technologies to guarantee precise simulation:
UV lamps naturally decay. LIB’s Eye-Lead™ sensor system monitors irradiance 100 times per second and automatically compensates lamp aging, keeping UV stress consistent from hour 1 to 5000+ hours.
Heat accelerates UV-induced degradation. LIB chambers manage:
Black Panel Temperature (BPT): Mimics the heat absorbed by dark surfaces under sunlight.
Chamber Air Temperature: Maintains stable ambient conditions, preventing local overheating.
This dual approach ensures that thermal and UV stress is accurately reproduced, providing reliable aging data.
100% Humidity Condensation: Creates dew to simulate chalking and gloss loss in coatings.
High-Pressure Spray: Ten precision nozzles simulate rainstorms after heat exposure. The automatic water supply and filtration system reduces water usage while enabling long-duration testing.
