UV radiation interacts with bonds in thermoplastics(Gpolymers) which can lead to degradation of the polymer chains and most damage occurs in the 290-400µm range. This degradation can lead plastic part surface to cracking, chalking, colour changes and loss of mechanical properties.
Accelerated artificial weathering is particularly useful for determining the inherent photostability of a thermoplastics material or the effectiveness of any UV stabilisers added.
Common UV Testing Standards

A typical cycle will expose thermoplastics samples to a combination of UV, heat and a moisture condensation phase.
European: ISO 4892-3, ISO 4892-2 & 11507
American: ASTM G154.
Ultra violet (UV) light accounts for around 5% of the sunlight received on the earth's surface and falls in the waveband 100-400µm. There are three UV bands (A, B and C) with wavelengths 400-320µm, 320-280µm and 100-280µm respectively.
There are several test methods for conducting accelerated UV weathering of thermoplastics materials. These include:
1) Outdoor exposure
2) Fluorescent bulb type tests (QUV)
3) Xenon Arc type tests.
