This project has developed measurement methods and provided data for the appraisal of 12 USAF-specified candidate halon 1301 replacements for compatibility with flight systems, people, and the environment. The exposures of metals, elastomers and lubricants involve an initial temperature and pressure of 298 K (77 deg F) and 4.1 MPa (600 psi), with a final temperature of 422 K (300 deg F). These data and those from the companion project, "Agent Screening for Halon 1301 Aviation Replacement," will enable the selection by September 30, 1993 of 3 of the chemicals for full-scale testing by the Air Force. Longer-term testing will then be commenced to increase confidence in the preliminary results for materials compatibility. A final report will be delivered by September 30, 1995.
