  Qualifying New Materials

  May 15, 2025 | Dr. Oliver D Rahaeuser

  Applications

  Qualifying new materials for new product development is one of the primary purposes of xenon-arc weathering testing. Typically, this is a stepwise approach involving comparative and extended testing as well as natural exposures.

  Weathering Basics II – Correlation and Relevance

  January 15, 2025 | Andreas Riedl

  Education

  In weathering testing, correlation usually measures how well an accelerated test predicts a material's property change in “real-world” environmental conditions over time. But correlation without relevance is meaningless: in addition to the macroscopic property change, the degradation mechanism on molecular level needs to be the same in both tests

  How Long do I Need to Test? Part 2: Estimations Based on Radiant Exposure

  February 23, 2022 | Dr. Oliver D Rahaeuser

  Education

  In an earlier post, we discussed the question by differentiating between three different test approaches or “why?” we run weathering tests. In this post, we will discuss the pros & cons of using radiant exposure as the basis for determining test duration.
