This document presents the findings from tests conducted by Patricia Cahill at the Wm. J. Hughes Technical Center, focusing on the burn performance of cotton swabs made from metallized Mylar and plain Mylar at sea level and altitude (8,000 feet). Results indicate that metallized Mylar cotton swabs had differing burn times of 1 minute 18 seconds at sea level and 1 minute 20 seconds at altitude, while plain Mylar swabs burned for 2 minutes 1 second at sea level and 1 minute 2 seconds under pressure. Additionally, the testing included flame propagation analysis.
