Performance of Special Extinguishment Agents for ... - UL.com

Issued: September 30, 2008
As can be seen from Figure 33, the heat release rate reduction for the agents tested versus water
as a baseline was quicker for all agents except one for the convective heat release rate.
As can be seen from Figure 35, the heat release rate reduction for the agents tested versus water
as a baseline was slower for all agents using the total heat release rate.
When reviewing the data for the average ceiling gas temperature of the nine thermocouples
positioned around the living room, we see the temperatures being reduced more slowly than with
water alone as can be seen in Figure 36. Note the thicker blue line represents the water baseline
test. In this chart, time zero represents the time of initial fire fighter attack.
Figure 36 – Living Room Ceiling Temperature Reduction Comparison
When reviewing the data for the average ceiling gas temperature of the four thermocouples
positioned along the centerline of the corridor, we see no significant difference in the
temperature reduction as shown in Figure 37. Note the thicker blue line represents the water
baseline test. Again, time zero represents the time of initial fire fighter attack.
