The final phase of study into RDX-based formulations suitable for replacement of tetryl in Australian ordnance is described. Three formulations using readily available AC629 emulsifiable polyethylene wax and processible on Australian production equipment are identified. It is recommended that pilot batch production and qualification of RDXAC629 98.751.25 for leads and small pellets, RDXAC629 96.53.5 for large boosters and RDXAC629zinc stearategraphite 98.01.250.50.25 for high production rate automatic pelletting be carried out. Performance testing has included propagation in small channels, fuze train function in Fuze Mk 162 and production automatic pelletting. US and UK qualified formulations have been similarly characterized and are compared.
