Recover any embedded debris. However, eertain basies are eommon throughout: Signature effects are those that characterize the use of a specific ammunition incidental to its intended performance.

It is possible that the shaped charge jet can start a delayed reaction in the target package through such effects as smoldering, heating, ignition of tracers or self destruct elements, etc. Fire the first round at the estimated R50 range.

The shooter should be provided with a test fixture, bench, or table to facilitate loading and firing the weapons. Measure the obliquity of the plate as near as possible to the aetual projeetile strike targets are rarely perfeetly fiat and the obliquity will vary slightly aeross the surfaee.

For example, a Teehnieal Feasibility Test may only require a small sample size whereas an Engineering Development Test designed to support a Milestone C deeision would require a mueh larger sample size see DTC Pamphlet for definitions of test types and milestones. ESD has the potential to initiate electroexplosive devices, electric primers, and sensitive fuze energetic material. The following orientations will generally be appropriate: There is no corresponding hazard classification test; however, the data from this test may be useful for that purpose.

In some cases a sheet of conditioning armor may need to be placed between the charge and the test item to condition the jet. The firing procedures and data recorded are somewhat dependent on the specific type of ammunition under test; at a minimum -42-602 the projectile velocities, dispersion, and weapon cyclic rates if the weapon is capable of automatic fire.

The ammunition and packaging is inspected prior to the start of testing and between each test. The obliquity must be measured before eaeh shot and after eaeh shot at the aetual strike loeation. The test itol used must be coordinated with the Army Fuze Management Office if the data is intended to support fuze qualification. However, the purposes of the two groups of tests are different. Each cartridge and ammunition package must be marked for unique identification before the start of the test.

Position a video camera behind the weapon in line with the weapon sights so as to photograph the target as would be seen by the firer. Provisions must be made for remote firing and proper protection of test personnel.

Examine the weapon bore with a borescope and record its condition; measure the bore at intervals of 25mm 1 inch for its complete length. A five round sample size should be fired under each required condition. Cartridges received for test are examined for damage and defects. The safety and suitability of recoilless rifle ammunition is interrelated with the weapons with which it is used.

Minimize safety hazards by using eartridges without explosive eharges ktop propellant. The inspections will reveal any damage to the ammunition was caused by ittop test procedure either individually or cumulatively. The data required will depend on the specifics of each test. For explosive projectiles fire one shot transversely into the body of the projectile and one from nose to base. When planning to test at temperature extremes, sufficient conditioning time should be allowed prior to testing tiop ensure temperature stabilization.

Bare projectiles should ito; provided with a means to activate their emitting devices and must be instrumented to determine susceptibility to the EMI. This is a test that simulates the Eleetromagnetie Radiation EMR environment to whieh the test item may be exposed to during its life eycle.

Ammunition may be exposed to salt-water immersion both for deliberate operations such as fording and for incidental occasions such as transportation in watercraft. Erect a second target function target of sufficient thickness to assure that an armed fuze will function. The weapon muzzle protrudes through the wall of the chamber so that gases from the muzzle do not enter the chamber. Firings are done from the weapon in which the ammunition is intended to be used.

If a physical target is used, inspect the projectile imprint for evidence of yaw, projectile deformation, etc. Determine the number of items for a drop eondition to determine the number required to start the 1. This test is effective for determining if the test item can withstand deep submersion such as for beach operations or flooded ship magazines.

Prior coordination of the procedure details should allow one test to satisfy both documents. Typical data recorded is: The witness plate is then examined to determine the number of complete perforations. Record the gross particulate size and the density of a sample. Typically, this is a Fourier Transform Infrared FTIR Spectrometer used to continuously measure concentrations of the gases emitted from the each weapon. This test is used to assess the potential for a munition to sympathetically react to the initiation of an adjacent munition of the same type.

Carefully purge the ehamber between trials and rewet the ground if neeessary.

The criterion is usually in the form of a percentage of hits that must perforate a given plate target at a given obliquity and range. The higher drop heights may require the use of aircraft; if so, the actual drop height must be verified by suitable instrumentation.

Possible results include projectile ricochet, projectile function on the first or subsequent itopp, and projectile embedment in the target media. Alternatively, itkp the area with an impenetrable barrier such as a large plastic sheet. Whenever a certain minimum sample size is specified in this TOP, the number is considered adequate to detect fundamental and consistent ammunition characteristics in a particular environment. Erect a functioning target behind the dowel array in the same manner as for the sheet material test, a minimum of ten meters is recommended.

If temperature conditioned ammunition is used, it should be fired within 5 minutes of being removed from its temperature controlled environment.

Itpp may require plowing followed by disking and dragging. Record the concentrations of toxic gases for ten minutes to permit complete mixing of the gases in the chamber. The flash test is used to determine the flash characteristics of the ammunition when fired. The standard test requires five cycles for a total duration of 10 days.

Examine the witness plate after any shot that does not result in an obvious eomplete penetration or obvious non penetration.
