Webinar: Correlation in Accelerated Weathering Testing

Accelerated weathering testing is a widely used method to quickly assess the durability of materials exposed to sunlight, heat, and water in outdoor environments. A key objective of this testing is to establish a correlation between laboratory and real-world performance. However, developing Acceleration Factors that accurately link accelerated and outdoor results can be challenging due to the complex nature of weathering processes. Combining both outdoor and laboratory testing can enhance the reliability of these correlations. Understanding the strengths and limitations of accelerated testing is essential to maximise the effectiveness of your test programme.

In this webinar, we will explore key aspects of accelerated weathering and its role in product development and quality assurance. Whether assessing compliance, enhancing durability, or addressing failures, a well-designed test programme offers valuable insights. Understanding testing methods and results enables informed decisions to improve product performance and meet industry standards.

In this webinar, we will explore:

• The “myth of reciprocity” and the challenges of establishing numerical correlation factors between accelerated and natural weathering tests.
• Selecting the right accelerated test methods based on specific goals, from quality control to new product development.
• Using rank ordering to determine correlation.
• Case studies that demonstrate successful correlations between outdoor and accelerated laboratory weathering and corrosion tests, including:
  • Printing inks
  • Flexible intermediate bulk containers
  • Coloured plastics
  • Vinyl siding
