UV Fluorescent Accelerated Aging Test Chamber

UV Resistance Tests are conducted to evaluate how coatings exposed to sunlight behave and degrade over time under environmental factors.

Based on outdoor environmental conditions, there are three main challenging parameters in this test. The first is the destructive effect of solar radiation. The second is the increased surface temperature caused by this radiation. The third is humidity.

In this UV Fluorescent Lamp Test Chamber, UVA or UVB lamp types are used to continuously expose the test samples to radiation at a fixed wavelength. Since the UV spectrum is the most harmful source of radiation from sunlight, it provides a highly destructive and rapid result, especially for painted parts.

In addition to UV radiation, the conditions are made even more challenging by the temperature and humidity parameters inside the chamber. The humidity parameter is created by the condensation of water vapor on the surface of the exposed sample.

These devices are particularly suitable for use in R&D stages or when product comparisons are required.

To operate this device, the following systems are required:

• • Pure water (with a conductivity of 5 μs/cm)

• • Water drainage system (for the disposal of used water)
