MIL-STD-398 Shields, Operational For Ammunition Operations, Criteria For Design Of And Tests For AcceptanceThis standard establishes minimum design criteria and test methods for acceptance of operational shields developed to protect personnel and assets from accidental or intentional detonation of explosives during ammunition surveillance, maintenance, modification, renovation and demilitarization operations or ammunition loading operations as defined in paragraph V1.E9.3.1.1 of DoDM 6055.09-M.

4.2.2  Test environment.

4.2.2.1  Simulated operational environment.  Unique shield designs destined for use at a specific location shall be tested under conditions that simulate the known location.  Shields using baffles, holding devices, or other means to prevent propagation of explosive items for which the shield provides protection, shall be tested to determine the effectiveness of the shield design in preventing propagation.  Explosive items used in the test shall correspond to those that can be involved in a maximum credible incident (i.e., the item undergoing the operation and such other nearby items as may be involved in propagation of detonation or deflagration originating at the operation) plus a 25 percent overcharge to compensate for the statistical inadequacy of testing.
