The small-scale cookoff bomb test was developed by the Navy at China Lake as a method for evaluation of the violence of thermal decomposition of explosives and propellants. The UN {open_quotes}Recommendations on the Transport of Dangerous Goods - Tests and Criteria{close_quotes} (ST/SG/AC.10/11) have accepted the small-scale cookoff bomb test as a test for classification of a substance as an explosive (class 1 substance) for storage and shipment. The US Departments of Transportation and Defense have agreed to use the UN tests as US criteria for storage and shipment. The UN scheme is designed to assess the relative hazard of explosives so that an appropriate classification for transport can be made by the competent authority (DOT). Three thermal tests have been approved: the Koenen test, the internal ignition test and the small-scale cookoff bomb (SSCB) test. Lawrence Livermore National Laboratory has designed a dissolution work station for removal of the plastic bonded explosives (PBXs) LX-10-1 and PBX-9404 from two artillery fired atomic projectiles (AFAPs) using dimethyl sulfoxide (DMSO) as the solvent. The DOE Explosives Safety Manual allows up to 33% solutions of explosives to be handled as non-explosive in the laboratory and 25% solutions to be stored as non-explosives unless the explosive precipitates out. In order to ship solutions of LX-10-1 or PBX-9404 in DMSO on US highways for waste or recycling as non-explosives, these solutions must be approved for shipping by the DOT based on the results of UN test series 1. The compositions of LX-10-1 and PBX-9404 are given in Table 1. The shock sensitivity of solutions of these two plastic bonded explosives in dimethyl sulfoxide (DMSO) has been evaluated using the UN series 1 gap test for liquids as described in a previous report. The purpose of this paper is to present the results of the SSCB tests on pure DMSO and 25% PBX solutions in DMSO to assist in the classification of these solutions.
