Bruceton Staircase technique

The Figure of Friction can be calculated in a similar way using the Bruceton Staircase technique, where the Figure of Friction for the standard explosive RDX is 3.0. Figure of Friction (F of F) values for some secondary explosives are presented in Table 4.4. 

The results are plotted using the Bruceton Staircase technique and the median drop height which gives 50% probability of ignition for the materials under test is determined. The Figure of Insensitiveness (F of I) is calculated using Equation 4.2.
