Recoilless rifle ammunition must not cause electromagnetic interference with other systems 4-2-60 should it be adversely affected by its electromagnetic environment. The AMFO requires numerous tests to be done in the life cycle of a fuze. The critical requirements are as shown itpo There are many possible Reeoilless rifle ammunition tests that are rarely needed but should be eonsidered in the planning proeess.
Some exterior ballistics tests require the use of physical or electronic targets; this allows the collection of dispersion data along with the ihop from the radar. All firings must be done remotely due to the possibility of damage to the tiop. Record all malfunctions in accordance with paragraph 5 of TOP Care must be taken to insure that the live test items are placed in locations that will experience the most severe environments. Prepare the drop package by placing the test items in their intended packaging and shipping containers and attaching them to the appropriate honeycomb or other shock absorbing system used in air delivery a parachute is not needed.
Conduct safety tests and high-risk tests first to provide an early indication of suitability. These tests should be done to assure basic ammunition safety and functionality before extensive firings are done. Fuzed munitions should be fired in two equal samples, one at the no arm distance and one at the all 4–2-602 distance. It is 4-2-60 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.
Data will be reeorded both at the firing position and aloft to the expeeted maximum ordinate.

At a minimum, one test ammunition container will be placed on a bottom corner and one will be placed in the most constrained bottom location. Fuzes are commonly used to initiate items such as a high explosive warhead and can also be used to create an incendiary effect. Recover any embedded debris.
The quantity is typieally split equally at the upper and lower temperature extremes. All maintenance actions will be recorded. Weapon lubricants, gas port settings, etc. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing this burden, to Department of Defense, Washington Headquarters Services, Directorate ito information on Operations and ReportsJefferson Davis Highway, SuiteArlington, VA Also reeord any diffieulties in operating the support weapon with the exposed ammunition such as excessive force required to charge the weapon, difficulty clearing stoppages, etc.
Set a simple paper target in place of the test item and fire a three round burst.
This test is done to determine if exposure to fungus will degrade the test ammunition. This test determines the effects of a salt-fog atmosphere on ammunition performance.
It may be necessary to use tracking radar if debris is projected to a range that makes witness screens impractical.
This TOP does not constitute a requirement to do any of the specific tests nor does it serve to set performance or safety criteria for Army materiel. This test is for unfuzed ammunition. This TOP does not speeify a fixed sample size sinee Reeoilless rifle ammunition paekaging varies greatly and is speeifie to eaeh test item. The original configuration of the fuze should be preserved and reattached to the projectile body.
The shooter should be provided with a test fixture, bench, or table to facilitate loading and firing the weapons. Ideally, the ricocheting projectile is tracked to ground impact.
It should be noted that this unclassified HEMP procedure may not be suitable for all evaluations.
Also record any difficulties in operating the support weapon with the exposed ammunition such as difficulty charging magazines, excessive force required to charge the weapon, increased maintenance 4-2-62, etc.
The gage is mounted in the barrel such that its sensing tip is in direct contact with the cartridge case which is not drilled. The smoke cloud accumulated at the gun during firing is evaluated from the standpoints of target obscuration when viewed from directly behind the gun and 4-2-62 or signature of the cloud 4–602 a distance beyond the muzzle. Typical requirements include incendiary effects, breeching capability, and penetration of walls and bunkers; other types of terminal effects requirements may also be encountered.
Each individual test will include exposure to at least 10 HEMP pulses.

The test cartridges are treated and inspected as indicated in paragraphs 6 and 7 above. Position witness screens at locations suggested by the results of the initial firings. At least two screens should be placed at intermediate distances. The test items are exposed eontinuously for 96 hours. A larger sample size must be used when marginal performance or randomly encountered ifop are expected and are to be measured with some degree of confidence.
Fire using the procedures above. Fuzed ammunition should also be fired for fuze function at the all armed range and at the no-fire range to verify that water has not impaired the operation of the fuze. It outlines test phases to be included and points out important features to be considered for each phase. The range should be long enough that projectile yaw has damped out, but short enough to permit accurate placement of projectile impact.
In such a case a package or array of test cartridges may be required to give reasonable assurance of a hit in a sensitive area. ITOPDrop Tests for Munitions, gives procedures, summarized below, for simulating parachute deliveries by vertical drop tests. After the inspections, the predetermined sample is removed for firing tests and the remaining ammunition and packing is retained for the loose cargo test.
It may be required to drop the pallet upside down and on its side to achieve the cartridge orientations. First do the tracked vehicle vibration schedules in accordance with Table B-3 of ITOPnext do the wheeled vehicle vibration in accordance with Figures B-1, B-2, and B-3, and finally do the two wheeled trailer vibration in accordance with Figures B-4, B-5, and B The ammunition will be submerged linked or clipped such that it is the configuration likely to be carried by an individual Soldier.
