Plastics UV Aging Tester simulates damaging effects of long term outdoor exposure of materials and coatings by exposing test samples to varying conditions of the most aggressive components of weathering - ultraviolet radiation, moisture and heat.
A UV weathering Test chamber uses fluorescent lamps to provide a radiation spectrum centered in the ultraviolet wavelengths. Moisture is provided by forced condensation, and temperature is controlled by heaters.
Besides natural weathering, several test methods have been developed using artificial light sources to provide accelerated test procedures. All methods are based on the regular observation of characteristics reflecting an ageing process such as mechanical properties (elongation at break, tensile properties or impact strength) or visible characteristics, such as crack formation, chalking, changes
In color or gloss.
The main testing methods for plastic material ageing are the following:
A) Natural weathering stations
B) Artificial accelerated weathering chambers:
- QUV fluorescent light source
- ATLAS Xenon lamp
- SEPAP chamber (medium pressure mercury arcs)
UV fluorescent light source:
Plastics UV Aging Tester have been developed to provide a UV weathering.
The UV simulates the effect of sunlight with fluorescent ultraviolet (UV) lamps, while rain and dew are simulated by the condensation of humidity. As stated previously, the UV light only represents roughly 5% of the sunlight but it is responsible for most of the polymer degradation. Also, materials are often tested with equipment, which simulate only the shortest wavelengths (UV). The UV-B range includes the shortest wavelengths found in sunlight. Therefore, for many applications, it is a fast and efficient method.
Plastics UV Aging Tester uses two main types of lamps: UVA-340 and UVB-313.
While these lamps have different light emission spectrum, they are both characterized by a maximum of emission in the UV range. UVA provides a reasonable match of the UV region of the solar spectrum, but this match is no longer valid for the long wavelengths (visible, IR).
UVB lamps also emit UV light, but the maximum of the emission spectrum is shifted towards short wavelengths compared to the UVA lamps. The UVB-313 lamp is a widely used type of fluorescent UV lamp that provides fast test results. However, the spectrum contains short wavelengths, which are not present in the solar radiation.
