All new and retrofit installations of Halon 1301 total flooding fire protection systems in shipboard machinery spaces require full acceptance discharge test. It is desirable to use a suitable simulant test gas in these tests in view of current and future regulation of Halon 1301. Sulfur hexafluoride, SF6, and chlorodifluromethane R-22, were identified as candidate simulants on the basis of their similarity in physical properties to Halon 1301. These two candidate were then evaluated on the basis of leakage from an enclosure. SF6 was determined to be an excellent simulant for Halon 1301 when considering leakage from an enclosure. Further testing of SF6 and R-22 is planned for other important aspects of Halon 1301 systems, i.e., flow hydraulics, initial mixing. Fluorides, Sulfur compounds Chlorine compounds.
