Applied Weathering Testing - Setups for Common
Test Methods
Test standard 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.
Consumer Electronics Photostability and Weatherability Testing
Modern consumer electronic contain a multitude of organic and polymeric components, ranging from seals, housings and covers to active components like liquid crystals and OLEDs. Those components can degrade or alter functionality by the influences of the environment, especially by solar radiation (natural or artificial), heat and moisture. This online seminar addresses these effects and provides information and methods how these issues can be tested during product development.
Hot-Light Fastness Testing
Automotive interior materials face extreme climatic conditions. Degradation can be caused by solar radiation (filtered by the cabin glass) under extremely hot temperatures. These extreme environments require special test conditions. Standards like ISO 105-B06 or SAE 2412 or OEM specifications define in more detail the temperature conditions and the optical filters required for Xenon-arc test instruments. This so-called hot-light fastness testing is addressed in detail in this online seminar.
Lightfastness Testing of Food and Beverages
Food and beverages can degrade by factors of the environment including natural solar radiation, but also by artificial light sources (Store-Light). These factors are often limiting the “shelf-life” of a product. This online seminar addresses special weathering and lightfastness test methods for the food and beverage industry, including testing of the product and it’s packaging, but also how the packing can protect the content from those environmental factors.
Pharmaceutical Photostability Testing
This online seminar
addresses photostability testing of pharmaceuticals focusing on the ICH Q1B
Guideline, with reference to World Health Organization (WHO) and other
standards. The presentation will cover the testing requirements of the
standards, ranging from the stability of the active ingredients to the final
pharmaceutical product. General principles and standards will be explained,
including areas of the standards that are vague or left to the discretion of
the researcher. You will also learn about which Atlas instruments are suitable
for testing.
Photooxidation and Stabilization Mechanisms
This online seminar
addresses the effects of light, heat and moisture on material degradation. What
effect does solar radiation have on materials? What is the influence of
temperature? How can the impact be estimated? Topics like spectral sensitivity,
activation spectra, and the Arrhenius equation are discussed. The most
important chemical degradation pathways are described. How can photooxidation
be controlled or be avoided?
Textile Testing: Colorfastness to Light
This seminar addresses the principles of natural and artificial lightfastness testing techniques for textiles. The purpose of reference materials for testing, evaluation and rating is explained. Examples are given on the most common test methods for textiles for interior (AATCC TM16, ISO 105 B02, Company specifications) and exterior applications (ISO 105 B04 and B10).
Weathering of Automotive and Transportation Coatings
This online seminar addresses test methods for automotive exterior materials, especially automotive coatings. The background and the motivation leading to the development of the new test standard ASTM D7869 “Standard Practice for Xenon Arc Exposure Test with Enhanced Light and Water Exposure for Transportation Coatings” will be in focus.
Weathering Technology: Applications and
Limitations of Different Types of Xenon-arc Instruments
Focus of this online
seminar is the comparison of rotating-rack type and flat-bed type xenon-arc
instruments. Both instrument types have their advantages and their limitations,
regarding uniformity of irradiance and temperature, specimen geometry and
sample handling. Those topics are discussed. Guidance is given on which
instrument types might be favorable for specific applications.
