History of Weathering

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.

Time Scales in Environmental Ageing of Polymers

Under the synergistic impact of solar radiation, heat, and moisture, all polymeric materials undergo chemical and physical ageing. These weathering effects lead to changes in properties and ultimately to product failure. Photodegradation, chemical, and physical processes, as well as external stresses run on very different time scales. Some effects can easily be accelerated. Others, like diffusion, migration, or water uptake need time to evolve. The result are fundamental limitations in the overall acceleration that can be achieved in an accelerated but correlating laboratory test. Knowing about the relevant aging processes and understanding their time scales and acceleration limits is critical to making the right testing decisions.
