Laboratory ignition and combustion data have been compiled for Hazard Division HD 1.1 and 1.3 substances. These data can be used to identify their hazards potential with respect to a thermal threat. In general, the ammonium perchlorate AP based HD1.3 substances are easier to ignite at low pressure than the HD1.1 substances, such as nitramine-based explosives. Burning rate as a function of pressure and initial temperature has been illustrated for samples of HD1.1, 1.3, and 1.6, Extremely Insensitive Detonating Substances EIDS. Convective combustion has also been illustrated. The effect of burning rate on friability data was illustrated for the three HD substances. Accounting for the effect of burning rate is necessary in order to quantify damage levels.
