ABSTRACT
The indirect evaluation of the maximum experimental safe gap for explosive mixtures involves the measurement of the quenching distance for different initial pressures and compositions. A study concerning the precision of the experimental method was made. The low values of the standard deviations of the parameters in the empirical correlations initial pressure/quenching distance and quenching distance/maximum experimental safe gap allow the conclusion that the propagation of uncertainty does not significantly affect the calculated safety gap, and the precision of the method is maintained in acceptable limits.
