Consideration must be given to interference between in-flight projectiles. The limited amount of test ammunition should be preserved for actual testing.

The lists below show specialized items that are used in the test procedures. The ammunition is dropped in its smallest shipping and storage container; this is usually the smallest configuration that has an individual security seal and is environmentally sealed against climatic conditions. All fuze eomponents sueh as eleetro explosive deviees EEDstab detonators, ete. Place a second video camera perpendicular to the muzzle of the test weapon at a distance that will record the expected smoke cloud; the background for this camera should be of a contrasting color and contain features to show the relative size of the smoke cloud an open field or the side of a building may be appropriate.

The fuze, projectile, and cartridge case should be assembled to their operational configuration.


A five round sample size should be fired under each required condition. Record the height of the weapon muzzle above the impact area, the weapon elevation, and the expected distance to impact. Other effects, such as noise and recoil, have safety implications. The number of rounds may be tailored for the specific type of ammunition and its service weapon, or to comply with requirements documents.

Typical data recorded is: If the first and seeond measurements from the repeatable position differ, the orientation of the target has ehanged as a result of the projeetile strike and the differenee of the two measurements must be used to eorreet the obliquity measured near the point of impaet.


All fuze components such as electro explosive devices EEDstab detonators, etc. The SLAB will record the necessary test data. Use the type of package as would be shipped from depot storage.

Note if any energetic element has functioned as a result of the discharges. Fuze function on such material has safety implications because the safe separation distance between personnel and the exploding projectile is often greater than the minimum no-armed distance.

Use the task checklists for individual weapons and for crew served weapons contained in TOPPart II, for guidance. Other projectiles, such as for target practice, may not have any specifications for terminal performance against targets, but their terminal ballistics are important for determining range safety considerations. If fewer than seven of each group is recovered, additional projectiles may be 4-2-6002 and fired.

The critical requirements are as shown below: Sample sizes are difficult to determine due to the commonly large shot-to-shot variability of results.

Use Procedure 1 Standard Test. Inert items ean not be used to meet the 0. Recover any embedded ittop.

Testing is done at extreme temperatures; test items may not be required to be functional at these temperatures.

Do not replace containers and packing material unless failure to do so would cause an undue safety hazard in subsequent testing. Position targets at the ranges indicated by the requirement documents or test plan. Data Required 1 Description of the test set up. Exeessive reeoil ean degrade training, injure the shooter, and damage weapon mounts. Examine the weapon bore with a borescope and record its condition; measure the bore at intervals of 25mm 1 inch for its complete length.

Note if any projectiles function on the dowels; if so note if the function is on, or in. The HEMP pulses should be applied remotely, and shielding should be provided to protect personnel and equipment. Photograph the area and provide a description of vegetation, existence of surface water, irregularities, etc. The safety and suitability of recoilless rifle ammunition is interrelated with the weapons with which it is used. Slowly rotate the cartridge degrees in a vertical plane, stopping momentarily with the bullet downward, and then continuing until the cartridge is projectile end up again.


Erect a second target function target of sufficient thickness to assure that an armed fuze will function. 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. Ammunition should not be used for multiple tests as conditioning in one environment might lead to a failure in another. Record all malfunctions in accordance with paragraph 5 of TOP Fire at a cadence of about one shot per minute.

The noise level may be hazardous to the shooter and to nearby personnel. If satisfaetory proeeed with the test. Initial firings are done to establish the initial divergence of any debris; this information is then used to modify the witness screen layout to best determine the maximum range and divergence of the debris.

These tests should be done to assure basic ammunition safety and functionality before extensive firings are done.

The choice of the specific procedure must be coordinated early in the test planning process. At a minimum all test samples must be fired to determine functionality in their intended weapon and to record their velocity.
