What Are the Key Parameters That Can Be Controlled and Monitored in a UV Accelerated Weathering Tester?

UV radiation

The intensity and wavelength of UV radiation can be controlled to simulate different levels of exposure. Generally, either UVA-340 or UVB-313 lamps are utilized.

Temperature

The temperature inside the chamber can be controlled and monitored to simulate the temperature variations experienced in outdoor environments. The temperature can be adjusted to specific levels or follow predefined cycles to replicate seasonal or diurnal temperature changes.

Humidity

The humidity level can be controlled and monitored within the tester to simulate different moisture conditions. This helps evaluate the material’s resistance to moisture-related degradation, such as mold growth, delamination, or dimensional changes.

Irradiance

The irradiance, or the amount of UV radiation reaching the material’s surface, can be measured and controlled. This parameter ensures consistent and accurate exposure levels across different samples or testing conditions.

Exposure Time

The duration of exposure to UV radiation and other weathering factors can be controlled and monitored. This allows for the simulation of long-term outdoor exposure in a shorter period of time, providing accelerated weathering results.
