Test Method Development

Solar radiation, heat, and water are acting synergistically on materials and components, causing ageing processes and ultimately product failure. Accelerated weathering instruments simulate and control these primary weather factors. This seminar explains how to develop a realistic, precise, and correlating accelerated weathering test method. The starting point is always the end-use environment, from which worst case conditions are derived, which are then translated into test parameters. ASTM D7869 is a recent example of such test method development. Often, multiple laboratory and outdoor weathering tests are combined into a “test program” that includes materials, components, and the final product. Examples form the automotive and PV industries will be discussed.

Weathering Testing - Common Test Setups

Standard test setups and cycles are the one side of the story, performing weathering tests in laboratory equipment are the other side. This online seminar should give guidance on how to translate standard test cycles into meaningful weathering experiments for common applications, such as automotive interior and exterior materials, plastics, textiles, composites, and other applications.

Comparison of Xenon-arc and Fluorescent-UV Technology and Applications

A common weathering question is “Which method shows better correlation; Fluorescent UV or Xenon-arc weathering”. Very often the answer is simplified to: Xenon-arc should be used if color change is an issue, Fluorescent UV should be used if matrix degradation is an issue. However, the answer is typically much more complex. This online seminar should help you to identify which testing technology is most suitable for your application. “When can Fluorescent UV be an economical testing option? When there is no alternative to Xenon-arc? What can be done for both methods to get the most meaningful results?”

Introduction to Weathering

This online seminar provides an introduction into technology, methods, and basic concepts of weathering testing. The seminar starts with explaining how weather factors cause ageing of organic materials. After that, the difference between weather and climate is discussed. The seminar reviews various outdoor testing technologies like static exposure, sun-tracking and the use of concentrating Fresnel mirrors and presents how testing is performed in key benchmark climate locations. Discussion of laboratory accelerated weathering testing is structured by light source and instrument geometry. Finally, the concepts of correlation and acceleration are briefly explained.

Weathering Testing of Automotive Exterior Materials

Automotive weathering testing is quite a wide field, where it is easy to lose track. There are test methods which are suitable for different materials (plastics, coatings on metals, coatings on plastics, textiles, leather, safety equipment, etc. Last but not least, different OEMs use different test setups and even different test technologies for specific applications. This online seminar should give you an overview on the most important weathering test methods such as SAE J2527 and AST D7869 in the automotive industry.

Weathering, UV Test, Solar Simulation, Photostability - Different Worlds or Different Words for the Same?

Accelerated Weathering, Lightfastness, UV, Photostability, Photodegradation, Shelf Life, Solar Simulation, Solar-Climatic, Accelerated Ageing, Environmental Durability Test, … Are these just different words for the same test? Or do these tests actually indicate different combinations of different stress factors? The key to understanding the differences and similarities is the applications. Different industries, e.g. the pharmaceutical, paint, PV, or textile industries and consequently different standards committees, have developed different testing philosophies adapted to their needs, their applications and their product life times. In addition, specific designations have been derived from different historical roots, e.g. from photography, electronics, chemistry, pharma, or material engineering. Finally, misleading terms such as "climate chamber" are widespread. This seminar dives deeper into the world of weathering and environmental ageing testing, discussing  different and similar concepts, defining and comparing the terminology used, explaining the historical background and correcting common misconceptions.

Temperature Effects in Artificial and Natural Weathering

The surface temperature of a material exposed to natural sunlight or to artificial Xenon-arc radiation is critical for its degradation behavior. In this webinar we present how surface temperatures can be measured in weathering setups and which test parameters will influence the surface temperature. We will show models and examples how the surface temperature influences the degradation process.

Weathering Testing - From Ranking to Service Life Prediction

Accelerated weathering testing is meant to reproduce the aging and the failure modes of materials and products in their targeted end use environment. Depending on test method, the test can be realistic in reproducing the effects of natural weathering. However, often accelerated tests are only used to rank materials and to select the best option. The higher goal is still to have real service live prediction based on accelerated testing. Approaches of service live prediction include modeling of material degradation based on climatic data to design test methods to reproduce natural failure modes. Detailed knowledge of product degradation mechanism in the end-use environment is important. There is a long way from simple accelerated weathering testing to real service life prediction. This webinar gives guidance to make the most out of accelerated testing.
