■"1 = percent reduction of combustion parameters (flame spread rate and weigfit loss rate) for untreated 

 fuel bed rates. 



2 = percent reducton of combustion parameters tfiat are computed using equivalent treatment amounts 

 and data (flame spread rale or weight loss rate) from pooled data curves for DAP. M-f^AP, and S-MAP. 



Tables 10 and 1 1 show the results of regression analysis and 

 "F" tests for regression differences. The program for 

 calculating "F" values is given in figure 1 . Figure 2 shows all 

 the weight-loss data on excelsior for DAP, M-MAP, and 

 S-MAP, and the pooled equation is plotted. Figure 3 shows 

 data and the equation for spread rate data on excelsior for 

 DAP, M-MAP, and S-MAP. Figures 4 and 5 are weight-loss 

 and spread-rate data on pine needles for all three chemicals. 

 Figures 6 through 9 show all data points for all three chemicals, 

 and individual best-fit equations are plotted for each chemical.
