The Sun's Effects on Outdoor Products
Applied Technical Services performs xenon arc testing to help clients determine their product’s resistance to environmental stimuli such as heat, moisture, and solar radiation. Outdoor products notoriously degrade over time: painted siding cracks and chips, while the colors of lawn furniture fade noticeably quickly the longer they remain in the back yard. These phenomena are just some of the numerous effects of the sun’s rays. Although our star emits energy of every type from the electromagnetic spectrum, most of it is filtered through Earth’s atmosphere, with primarily infrared, visible light, and ultraviolet (UV) rays making their way to the surface. This combination of energy produces a variety of effects, ranging from aesthetic changes such as color fading to mechanical changes such as weakening coatings. Manufacturers trust their outdoor products to third-party testing specialists, such as ATS, to verify how their samples react under accelerated sunlight testing.
Our Xenon Arc Testing Capabilities
ATS’ environmental testing division performs the xenon arc method using advanced weathering testing equipment. These instruments produce solar spectrum radiation by using a xenon bulb. Our technicians can expose the sample directly, which mimics uninterrupted sun exposure, or through a pane of glass, which replicates the conditions incurred by automotive interior materials. By also controlling the chamber’s temperature and relative humidity, our technicians can faithfully reproduce day and night cycles to determine how products will react under these circumstances. Our instrumentation can even simulate rain by introducing water spray to validate how they perform under thermal shock.
We perform xenon testing to a long list of standards, the full extent of which you can read here. The following reflects our most requested specifications, as well as the list of xenon arc testing services for which we maintain ISO 17025 accreditation through the A2LA:
