Modern xenon arc instruments, equipped with state-of-the-art optical systems and parameter control, deliver the best accelerated simulation of primary weather factors. Therefore, xenon arc laboratory weathering testing is a must for any material or product approval. However, fluorescent/UV condensation devices can be very helpful, e.g. for screening or assessing UV sensitivity of non-colored materials or clear coats.
Understanding applications, comparison, and limitations of different laboratory accelerated technologies is critical to perform the most meaningful test.
