This wooden dowel test is most appropriate for projectiles of 40mm or greater as smaller caliber projectiles may pass through the array without impacting the most sensitive area of the fuze.
The witness plate for calibers above 40 mm is mild steel 1. Typical requirements include incendiary effects, breeching capability, and penetration of walls and bunkers; other types of terminal effects requirements may also be encountered. The angles are usually defined iotp being between 80 and 90 degrees obliquity; however, lesser obliquities may be specified for high angle of fire weapons such as grenade launchers. ITOPDrop Tests for Munitions, gives procedures, summarized below, for simulating parachute deliveries by vertical drop tests.
Both the personnel bom and helieopter born diseharge sequenees are required.

Gusty winds adversely affect both accuracy and dispersion measurements and should be avoided. Consultation with individuals experienced in this testing should be done as early in the planning process as possible. 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. Explosive ammunition must be examined remotely.
Eor example, a Technical 4–2-602 Test may only require a small sample size whereas an Engineering Development Test designed to support a Milestone C decision would itlp a much larger sample size. The barrels used for this test are typically Mann Barrels.
The obliquity must be measured before eaeh shot and after eaeh shot at the aetual strike loeation. This test provides a method of assessing the reaetion, if any, of a munition to the impaet of a ealibrated fragment representative of a bomb or artillery fragment. If a physical target is used, inspect the projectile imprint for evidence of yaw, projectile deformation, etc.
Visual observations are not reliable, particularly for those fuzes that may function behind the target. Examine the weapon bore with a borescope and record its condition; measure the bore at intervals of 25mm 1 inch for its complete length.
Ktop alignment is checked before each shot is fired. The outgoing elevation and azimuth of the projectile can be determined by tracking radar preferred method or by witness screens as described in ITOP Terminate the test if debris no longer makes any impression in the sereens or the range beeomes too far to be praetieable. Requirement documents or the Request for Test Services may require that a complete pallet of the test ammunition be subjected to tiop Remove the cartridge from the temperature facility and hold it vertically, projectile upward.
Consult with the evaluator and customer to assure a mutual understanding of the required angle of obliquity; some specifications assume that the obliquity is measured from jtop line of sight between the weapon and the target rather than from the trajectory. Recoilless rifle ammunition is exposed to high levels of salt in the atmosphere during coastal operations, marine transport, and operations 4-2602 salt lakes and salt deserts.
There are also operational implications if the fuze sensitivity limits the tactical use of the munition, such as in heavily foliated areas.
Meteorological data, such as winds aloft, are required up to the expected maximum ordinate. Targets, such as paper or ktop may also be used; these targets will not allow the projectile to function and will leave unexploded ordnance on the range.
Record the gross particulate size and the density of a sample.

Conversely, weapons subjected to unattended conditions, such as temperature conditioning, are not conditioned loaded as there is no continuous hand on control. After itpp inspeetion, all the ammunition is fired and its veloeity is reeorded for eomparison to ammunition that has not been exposed itpp the thermal shock test.
This 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.
Ground 42–602 Ballistie Pendulum, aeeuraey, Blast Overpressure, ete. The distances for the first shot and following shots are determined from statistical tables and a computer program.
The weapon should be in the lightest configuration in which it is likely to be employed. If the type of sand and moisture content is not stated in requirement documents or the RFTS, use the same No.
