In addition to real-world tests, Nissan engineers use the Xenon Weather-Ometer machine to test paint, interior materials and plastics for durability.


On the darkest day of the year Nissan engineers in Michigan are still performing sunlight ultraviolet exposure tests thanks to the Xenon Weather-Ometer (XWO) tool that evaluates material durability in different climate conditions.

To evaluate the effects of solar energy on paint and other materials, a 4,000W Xenon bulb bakes nearly 100 samples at the same wavelengths as the sun. Samples rotate around the Xenon bulb to imitate earth's orbit - and because the 'sun' can shine 24 hours a day, it takes half the time to test paint samples. Engineers observe the material samples through a series of cycles to investigate changes and ensure top durability and quality for Nissan customers.

Nissan uses test environments like the XWO accelerated weather chamber to replicate conditions that occur in a natural environment, right inside the lab. These test cells expose various types of material samples to a wide range of conditions that a vehicle may face throughout its lifecycle.
