This orientation allows the best aeeess to the target plate and witness 4-2-6002 however, it will generate rieoehets well off the line of fire. Downloading the ammunition changes the velocity to spin ratio of the in-flight projectile; this may be insignificant or it may be important enough to require that special gun barrels be procured to reestablish the proper ratio. Fuzed ammunition should also be fired for fuze function at the all armed range and no-fire range to verify that the temperature exposures have not impaired the operation of the fuze.
The ammunition is inspected, marked for individual identification, and its location within the drop package is recorded. For some tests, and because of safety precautions, it may be more realistic to condition the support weapons “half loaded”, i.
The witness plate for calibers above 40 mm is mild steel 1.
The list below gives general requirements, it is not all inclusive. If water is used as an impact media, the impact angle must be controlled by raising the weapon above the level of the water and firing in ittop. Graze sensitivity is the ability of the fuze to be initiated by a low angle impact with a horizontal target. After the inspections, the predetermined sample is removed for firing tests and the remaining ammunition is retained for the 1.
For ammunitions, this test is either the first or second step of a sequential rough handling test series. One weapon should be new and the other used, the latter being a weapon previously fired to near the end of its service life.
FR/GE/UK/US INTERNATIONAL TEST OPERATIONS PROCEDURE (ITOP) 4-2-602 ROUGH HANDLING TESTS
When there is minimal testing conducted during early development and the design has not been adequately proven, the safety testing quantities need to be increased. Measuring lethality is a highly specialized field requiring unique test techniques, such as firing into gelatin blocks, and expert data analysis. 42–602 proeedure is done with the same methods as the R 50 proeedure exeept that the range is held eonstant while the target obliquity is varied between shots.
Examine the witness plate after any shot that does not result in an obvious eomplete penetration or obvious non penetration. Each cartridge and ammunition package must be marked for unique identification before the start of the test. Existing roads, concrete pads, etc. For example, provide military issue cold weather gloves to weapon operators during extreme cold functioning tests and observe itpp the ease of unpacking the ammunition and loading a weapon. These gages are generally only used for acceptance procedures in manufacturing plants.
Witness screens may be needed to determine if fragments and splinters are blown back to the shooters position or the positions of friendly troops. Inspect any interior packing material for wear or other damage.
Recover any embedded debris. The target impact plate may block the path of projected fragments so its size and material must be carefully considered. Consideration must be given to the possibility of combining data from separate test procedures to effectively increase sample sizes and confidence in results. The number of test samples needed depends heavily on the type of test and what the test results are expeeted to aeeomplish or support.

Numerous other documents relevant to testing Recoilless Rifles systems are referenced throughout the document. Note if any projectiles function on the dowels; iitop so note if the function is on, or in.
Before disturbing the target, remeasure the obliquity at the repeatable position. However, the likelihood of rieoehets ean be a serious range safety eonsideration. Record the depth and temperature of the water. A steady, unvarying wind has a moderate effect on dispersion but can seriously affect 42–602 measurements. However, the test items are normally required to be fully functional at their designed temperatures after exposure to the thermal shock environment. This test is used to assess the potential for a munition ittop sympathetically react to the initiation of an adjacent munition of the same type.
Superscript numbers correspond to those in Appendix A, References. The test item will be subjected to three discharges from the lighting simulator. The basic ballistic data of velocity versus time is recorded by use of Doppler radar. The climatic design types, extracted from AR are shown in Table 1.
If a natural body of water is used, take care to do the test only when the water surface is calm and smooth. Record all malfunctions in accordance with paragraph 5 of TOP There are also operational implications if the fuze sensitivity limits the tactical use of the munition, such as in heavily foliated areas.
Additional low level wind data may be required between the weapon and the target area. Assure that the barrel does not become overheated; it should not be too itpo to hold in a bare hand. Larger caliber ammunition, particularly fuzed ammunition, should be weighed before and after being submerged. If at all possible, the outgoing projectile should be tracked to near ground impact, or 4-2-6022 a predetermined low velocity cutoff.
The other half should be eonfigured as would typieally be earried by an individual Soldier linked ammunition should remain linked, rifle and pistol ammunition itlp be loaded into itpp. If a physical target is used, inspect the projectile 4-22-602 for evidence of yaw, projectile deformation, etc. Assure that velocities, weapon cyclic rates and bullet dispersion are within requirements.
Measure the location of the marks relative to the line of fire. Test techniques are unique to each item. The data required will depend on the specifics of each test.
Many Recoilless rifle ammunition specifications and requirement documents give a single criterion for armor penetration capability.
Again fire a sample of rounds, scrutinize the screens, and measure the location of the marks relative to the line of fire. Larger calibers may be shipped in single containers. Assure that the transducers are properly calibrated before use. Lethality is itkp measure of the ability to cause death.
Fire the samples at range ambient temperatures unless otherwise specified in requirement or planning documents.
