UV Accelerated Weathering Tester

Recreate Years of Outdoor Exposure in Just Weeks

The UV accelerated weathering tester brings industry-proven performance to laboratories seeking faster, more reliable durability validation. By using precision-controlled UVA-340 or UVB-313 lamps, it replicates the most destructive portion of sunlight responsible for material degradation. An advanced condensation cycle simulates real-world dew conditions—often more aggressive than rain—accelerating failure mechanisms such as cracking, fading, and loss of strength. With SOLAR EYE irradiance control ensuring stable light intensity and full compliance with ISO 4892, ASTM G154, and SAE J2020, it delivers highly repeatable, globally recognized test results.

Why UV Aging Testing Ensures Accurate and Reliable Weathering Results

Targeted UV Exposure – Focusing on the Most Destructive Wavelengths

QUV testing concentrates on short-wave UV (295–365 nm), the primary cause of material degradation.

  • UVA-340 lamps simulate natural sunlight with high accuracy

  • UVB-313 lamps accelerate aging for rapid failure detection

Condensation Simulation – Replicating Real Moisture Damage

Many materials fail due to dew formation and long-term humidity exposure, not direct rainfall.

UV systems reproduce this through controlled condensation:

  • Heated water creates saturated vapor

  • Cooler sample surfaces form uniform condensation

LIB industry integrates precise condensation control to ensure stable and repeatable moisture testing.

SOLAR EYE® Control – Maintaining Long-Term Test Stability

Lamp aging can cause irradiance drift, leading to unreliable results.

UV’s SOLAR EYE® system solves this by:

  • Real-time UV intensity monitoring

  • Automatic irradiance adjustment

  • Stable long-term exposure conditions

At LIB industry, this ensures:

✔ Consistent test data
✔ High repeatability
✔ Reliable certification-level results
