WebThe typical all-fire design requirement is a 50 millisecond pulse at the minimum allfire level which causes the device population to initiate not less than 99.0% of the time at a confidence level of 95%. The test samples are typically divided into groups and temperature conditioned at -80°F, +70°F or +225°F. WebNov 8, 2024 · In these cases, the heat transferred from the bridgewire exceeds the ignition temperature of the acceptor and is sufficient to cause deflagration of that material. The energy of this deflagration may be used to further ignite a pyrotechnic, propellant or explosive output. ... BKNO3, black powder, or Red Dot double base propellant.
