Under this research effort, Halotron® I also was tested on three-dimensional inclined-plane fire tests, 16-ft pan fire tests, and 30-ft pan fire tests. Halotron I’s performance on the simulated engine nacelle fire tests was previously evaluated in NAWCWD TM 8572, the results of which were used as data for this evaluation. Data from these tests were used to compare Novec 1230’s performance with that of Halotron I. While Halon® 1211 is still an FAA-approved clean agent for use at airports, ARFF vehicle manufacturers have not installed Halon 1211 extinguishing systems on their products in over a decade.
Throughout all experimental configurations, Novec 1230 required more agent by both weight and volume than Halotron I. The difference between performance parameters by percentage were consistent between the three experimental configurations with the exception of the simulated engine nacelle conducted by the United States Air Force and Navy. The results of the simulated engine nacelle tests were comparable with the results of the other experimental configurations with the exception of extinguishment time.
