Part 2 of Q-Lab's 3-Part Summer Webinar Series

Performing natural and accelerated laboratory weathering testing is essential to understanding the performance of materials exposed to sunlight, heat, and water in many harsh outdoor environments. However, the exposures are only a part of the overall test program. To evaluate a materials' true performance, evaluations are needed in order to quantify the changes that the specimens have undergone. A wide range of evaluations can be performed based on the objectives of the test – visual inspections, color change, gloss loss, physical testing, and more.

This webinar will be presented by Q-Lab Test Services Technical Director Mike Crewdson. With 41 years of weathering testing experience, including 28 years as chair of ASTM's committee on Evaluation of Weathering Defects, Mike is the world's foremost authority on performing and analyzing weathering evaluations. Mike is also an A2LA-certified ISO 17025 Internal Auditor and Lead Auditor, as well as the author of key ASTM weathering standards on Terminology, Statistics, and Specimen Handling.

Mike will provide a comprehensive introduction to performing evaluations before, during, and after weathering test exposures, including:

• What are evaluations and why are they so important
• Which are the best evaluations to choose
• What kind of data does each evaluation yield
• What do those rating scales mean
• Recommendations for evaluation frequency
• How evaluations improve test variability and decrease uncertainty
• How to use the data to make key decisions
  

Join Q-Lab for this all-new session to learn how to maximize your weathering exposures with proper evaluation intervals, techniques, and assessment of results.

This webinar will be presented in English.
