Abstract

This paper presents the development of a test system to evaluate the ignition susceptibility of several common plastics in nitrogen trifluoride (NF₃) as compared to gaseous oxygen. A test system was developed to allow for measurement of the autogenous ignition temperature (AIT) in both gaseous oxygen and NF₃. The autogenous ignition temperatures of Kel-F® 81 PCTFE, Neoflon® PCTFE⁵, Teflon® PTFE, Nylon 101, PVDF, and PVC were determined in gaseous NF₃ and in gaseous oxygen.
