The work discussed in this paper is part of a larger
effort at NIST focused on finding an alternative to
halon 1301 for application to aircraft engine nacelle
and dry bay in-flight fire protection. Alternative
chemical compounds are sought which will perform
similarly to halon 1301, and whick do not create
unacceptable safety, environmental, or systems
compatibility problems. A cup burner, an opposed flow
diffusion flame, a turbulent spray flame, and a
deflagration/detonation tube are being used to rank the
relative combustion suppression effectiveness of the
following agents: R-32 (CH2F2), R-32/R-125
(CH2F2/CHF2CF3), HFC-227 (C3HF7), R-22 (CHF2Cl),
HFC-134a (CH2FCF3), FC-116 (C2F6), HCFC-124 (CHFClCF3),
R-125 (CHF2CF3), FC-218 (C3F8), FC-31-10 (C4F10), and
FC-318 (cyclo-C4F8). Table 1 lists the fuels and agents
to be evaluated and the experimental variables for each
