UV Weathering Testing Machine

Name: UV Weathering Testing Machine
Brand: Xi'an LIB Environmental Simulation Industry

LIB UV weathering testing machine utilize ultraviolet (UV) light of specific wavelengths combined with temperature(Ambient ～ 90 ℃ ±2℃) and humidity(≥95% RH) control—and meantime water spray/condensation—to accelerate the simulation of material degradation caused by long-term outdoor exposure to sunlight (particularly UV radiation), rain, dew, and temperature fluctuations.

It replicates years or even decades of natural outdoor aging effects in just weeks or months. These effects include: fading or discoloration,loss of gloss,,molecular degradation and etc.

Model: UV-SI-260

Standard: ASTM G154, ISO 4892-3，ISO 4892, SAE J2020,EN 1297，IEC 60068-2-5

UV Weathering Testing Machine Features and Benefits

1. Accelerated Aging Simulation
Simulates months or years of outdoor UV exposure in just a few days or weeks. Ideal for assessing long-term durability of materials under harsh environments.

2. Stable and Repeatable Conditions
Equipped with fluorescent UV lamps (UVA-340, UVB-313) that provide consistent irradiance (typically 0.68–1.55 W/m² at 340nm), ensuring high repeatability and reliability of results.

3. Customizable Test Cycles
Supports a variety of test cycles combining UV light, condensation, and spray. Typical cycles follow ASTM G154 or ISO 4892-3 with programmable settings.

4. Energy-Efficient Design
Fluorescent UV lamps consume less energy and have longer lifespans (up to 1600 hours), reducing operational costs.
