UV radiation testing

Ultraviolet radiation (UV) is a specific range of light on the electromagnetic spectrum. It is invisible to humans because its wavelength range is beyond the limit of human perception.
UV radiation can impact the performance products and components. Many natural and synthetic polymers are attacked by ultra-violet radiation, and products using these materials may crack or disintegrate if they're not UV-stable. The problem is known as UV degradation, and is a common problem in products exposed to sunlight. Continuous exposure is a more serious problem than intermittent exposure, since attack is dependent on the extent and degree of exposure.

UV degradation in materials testing
UV radiation tests are used to test products and components under solar radiation conditions. In this process, products and components are subjected to ultraviolet exposure in a controlled environment. A solar simulator is used to create ultraviolet radiation and simulate months or years of exposure.

These tests allow us to reproduce the conditions a product is likely to be exposed to during its life time. Testing is done in accordance with EN 61439-1 Resistance to ultra-violet (UV) radiation.
