This session will aim to answer a few questions: what does ‘high temperature’ mean; are the standards that are currently being used enough to support those claims; and do materials that claim high temperature have the best chance of meeting the physical requirements of today’s built environment?

Existing standards addressing elements of elevated temperature, such as accelerated aging, sample conditioning (AAMA 711 section 5.5), and visual assessment (ASTM D1970 section 7.6) are generally inadequate and incomplete.

This paper will look at common standards and claims regarding “high-temperature” and put them in the context of their respective applications.

1. Define ‘high temperature’ for building enclosure materials and applications.
2. Understand the standards that are currently being used for high-temperature.
3. Demonstrate the connection between high-temperature exposure and the performance of materials in these applications.
4. Understanding the importance of specifications and designing for high-temperature applications.
