It all started in 1906, when the first systematic outdoor weathering test was conducted in Dakota, USA. 10 years later, the “Solar Determinator” started the carbon-arc era. In 1956, the introduction of the Xenotest 150 was the beginning of xenon-arc weathering, still being today’s method of choice for most applications.

For the last 115 years, outdoor testing technologies evolved from static racks to sun-tracking exposure, and finally to accelerated devices with mirrors concentrating the sun on a target board.

The history of weathering is an exciting example how various academic and technical disciplines bundle their efforts to drive technical progress in material science, technology, test method design, and service life prediction.

In this Online Seminar you learn about the following technologies, from a historic perspective: 

  • Static outdoor exposure and solar tracking
  • Concentrating sunlight with Fresnel mirrors
  • Enclosed and sunshine carbon-arc
  • Photodegradation testing with mercury lamps
  • Fluorescent/UV testing
  • Xenon-arc weathering
