The tests were conducted for a wide range of operating conditions and produced a variety of droplet size distributions. Ideally, a small scale test could be used to investigate only the worst case droplet size distribution produced by residential sprinklers. FM Global Class Number 6930, Approval Standard for Flammability Classification of Industrial Fluids, was identified in Phase I of this project as a test method that could be adapted to investigate the potential for ignition of antifreeze solutions.
For example, Figure 15 shows that the 40% propylene glycol solutions result in some increase in the heat release rate of the initial fire at certain flow rates. The increase in heat release rate can be included in one of two categories: 1. Ignition of antifreeze spray that reaches the ignition source; or 2. Ignition of antifreeze spray extending away from the ignition source. 1007/978-1-4614-3840-3_5, © Fire Protection Research Foundation 2010 37 38 V Analysis Based on the tests conducted, it appears that some portion of the antifreeze spray reaching the fire source will ignite even for the lowest antifreeze concentrations tested and even when the antifreeze spray could be expected to extinguish most anticipated fire sources in a residential occupancy.
E. the fuel contributed by the spray burner was a function of the heptane flow rate and was not impacted by the antifreeze spray. In addition, it provided a conservative assessment of the potential for ignition, because many fire sources would be extinguished even by antifreeze solutions that had a significant increase in heat release rate during the tests. Even the lowest antifreeze concentrations tested resulted in some increase in heat release rate when exposed to the heptane spray burner fire for certain test conditions.
