App Note: OptiFlash COC: Advanced Functionality Flash Point Tester with UV Sensing for Thermally- Expanding Roofing and Paving Asphalt Applications

OptiFlash COC: UV Flash Point Testing for Asphalt

PAC’s application note explores the use of the OptiFlash COC UV-sensing system for flash point testing of challenging asphalt samples, including polymer-modified asphalt and materials containing recycled components such as RAP, RAS, and Ground Tire Rubber (GTR).

Traditional ionization detection can encounter difficulties with samples that thermally expand, bubble, or foam, potentially causing false or prematurely detected flash points. The OptiFlash COC’s UV-sensing approach detects the flash without requiring an ionization ring, helping address these challenges while reducing cleaning requirements.

Key highlights include:

• Comparison of UV sensing and traditional ionization detection for flash point measurement.
• Testing of challenging, thermally expanding asphalt samples containing Ground Tire Rubber (GTR).
• Repeatable flash point results without false flash triggering caused by bubbling, heavy vapors, or thermal expansion.
• Test data showing no differences between UV and ionization detection results for the ASTM D92 standard reference samples evaluated. App Note – OptiFlash COC for As…
• Guidance for configuring the OptiFlash COC for UV-sensing operation.

Discover how UV sensing can help overcome common flash point testing challenges associated with roofing, paving, recycled, and other difficult-to-handle asphalt samples.
