Internal Ignition Test Description Test Purpose The internal ignition test determines if the test material will transition from a deflagration to an explosion under high confinement. If this test result in a positive result then the material should be classified as an explosive in a manufacturing operation. Equivalence This test […]

Zero Gap Test Description Test Purpose The zero-gap test determines whether the material can propagate a detonation from high confinement and defined shock (~200 kbar). If the material can propagate a detonation, it should be classified as an explosive (Class 1.1 if also easily initiated) in a manufacturing operation. Equivalence […]
Recommended Test Setup: SBAT Test Purpose The purpose of completing the in-process thermal test is determine the effects of time and temperature on energetic materials in the process configuration. Thermal tests generally consist of measuring a sample’s response to either: (1) gradually increasing the temperature and recording the temperature at […]
ABL ESD Machine Description Test Purpose The purpose of completing electrostatic discharge (ESD) sensitivity tests is to measure the sensitiveness of a material to ESD. The transition from no reaction to reaction must be determined to evaluate in-process risks. The in-process potential from esd scenarios is compared against the material […]
ABL Friction Machine Description Test Purpose The purpose of completing friction sensitivity tests is to measure the sensitiveness of a material to friction insults. The transition from no reaction to reaction must be determined to evaluate in-process risks. The in-process potential from friction scenarios is compared against the material response. […]
MBOM Impact Machine Description Test Purpose The purpose of completing impact sensitivity tests is to measure the sensitiveness of a material to drop-weight impact. The transition from no reaction to reaction must be determined to evaluate in-process risks. The in-process potential energy from impact scenarios is compared against the material […]
Test Details Test Purpose The purpose of completing propagation testing is to determine whether a reaction from a finished or unfinished article, which was accidentally fired or initiated, will propagate to other articles or parts of the process. Articles are placed in the process configuration (worst case) and initiated or […]
Test Details Test Purpose A stack of unfinished or finished articles as they appear in the manufacturing line is placed on a non-combustible surface (steel grate) above a lattice of dried wood soaked with diesel fuel or equivalent source. A wire basket or clamps may be used to hold the […]
Test Details Test Purpose This test determines whether an operational shield is adequate for protecting personnel from a maximum credible incident (accidental) plus a 25 percent overcharge based on the following acceptance criteria as outlined in MIL-STD-398: Blast Attenuation: Shields shall be designed to prevent exposure of operating personnel to […]
Test Details Test Purpose The objective of a siting evaluation is to protect personnel and facilities from explosive or other highly reactive operations through proper facility design or separation. The quantity of explosives and the required distance of separation (QD) determines facility siting. The QD tables as used by accepted […]
