Weathering the Storm on Durability Testing
iest, tri

This one-day course emphasizes lightfastness and weathering durability testing techniques. These techniques include natural and accelerated outdoor exposure testing as well as laboratory accelerated weathering test methods and instruments for both small and intermediate scale testing.

The course will introduce the basics of how various factors of weather and climate (such as solar radiation, heat, and moisture) affect materials and how to test the resistance of a formulation or product to these factors. Special attention is given to the testing techniques of paints and protective coatings, automotive materials, architectural building products, and molded plastic materials. Textile and fiber lightfastness and weatherability are also discussed.

Course outline

  • The primary weather factors that affect the durability of materials
  • National and international test methods that govern natural and accelerated outdoor testing techniques and environments, with a focus on military test method applications.
  • Steady-State and Diurnal test strategies are evaluated and contrasted for material durability and thermal load type testing.
  • Artificial laboratory weathering test methodologies
  • How to properly structure a weathering test to derive maximum value
  • The importance of evaluations, procedures, and practices
  • Tailoring of test conditions and parameters are discussed as they relate to material durability testing, end-use climatic conditions, data development, and analysis.
  • Understanding concepts of test acceleration and correlation to outdoor service life

  • Who should attend?

    The course introduces the fundamentals of natural and accelerated weathering to professionals involved with designing, evaluating, specifying, selling, or purchasing materials or products that could be affected by exposure to light or weather. This includes materials engineers, product managers, marketing and sales managers, R & D personnel, and formulation chemists or anyone needing to understand weatherability and its effect on materials.
