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.

METHOD 301

5.2  Test procedure.

5.2.1  All instrumentation shall be within calibration at time of test.

5.2.2  If the shield is designed for use with more than one model or type of ammunition, select the item for the greatest heat flux.

5.2.3  Apply an overload equal to 25 percent or more of the filler weight of the ammunition selected for the test, unless otherwise directed in an approved test plan.

5.2.4  All major explosive components should be fused separately, to insure simultaneous detonation or deflagration, in order to simulate the maximum credible incident, unless otherwise directed in an approved test plan.

5.2.5  Function explosives and record radiant flux readings.

5.2.6  Prepare heat flux-distance and heat flux-time plots from radiant heat flux recordings.
