Remove a sample of ammunition after the 2. The high humidity environment can also adversely affect propellants and other energetics if the cartridge is not totally sealed.
Inspect the fired cartridge cases for evidence of splits, primer leaks, etc. All fuze components such as electro explosive devices EEDstab detonators, etc. The support ammunition is used to check out test set ups and instrumentation function, and to perform trial runs prior to the use of the test ammunition.
Fire at a cadence of about one shot per minute. The objective of this test is to ensure that the ammunition is safe to handle and dispose of after being subjected to a 12 meter drop.
The usual scenario is to record fumes produced by a single shot, by a short burst of five rounds, and a long 42-602 of 20 rounds. Examine the weapon bore with a borescope and record its condition; measure the bore at intervals of 25mm 1 inch for its complete length.
Table A4 gives the minimum test frequencies for each frequency range.
For large plates the hardness and thickness should be measured in a grid pattern, a spacing of mm is 42-602 appropriate. Consideration must be given to interference between in-flight projectiles. Record projectile velocities for each shot. The 4-2-6602 must be the exact package that will be used for shipping and storage. 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 depression.
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. Fire using the procedures above. Measure the obliquity of the plate as near as possible to the aetual projeetile strike targets are rarely perfeetly fiat and the iotp will vary slightly aeross the surfaee.

Disturb the items as little as possible and do not make any adjustments during the drying period. Using cartridge dummies or mass models to complete filling a package should be used only as a last resort as it is difficult to assure that these items truly replicate the vibrational characteristics of test ammunition. The standard procedure uses two hour exposures and two hour drying periods for a total of 48 hours of exposure to the salt-fog and 48 hours of drying; this test duration may be tailored to correspond to requirements documents, test plans, etc.

Exeessive reeoil ean degrade training, injure tiop shooter, igop damage weapon mounts. Gusty winds adversely affect both accuracy and dispersion measurements and should be avoided. The test is normally fired at range ambient temperatures.
A hole diameter of about ten times the projectile diameter will suffice. All packing, bandoliers, cartons, etc. Typically a high speed camera is used to record the flash.
This may make it difficult to obtain the required velocity while staying within the TB range limitations of 3 to 20 meters.
For insensitive munition qualification the use of the 81mm shaped charge must be supported by the Threat 4-2-620 Analysis authority. One half of the test ammunition should be in a eompletely bare 4-2-6022. Its primary disadvantage is that it requires range facilities to accommodate long range firings; also, the target size needed to assure a good probability of a fair hit may become uneconomically large or even impossible.
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 for information on Operations and ReportsJefferson Davis Highway, SuiteArlington, VA If desired, the data is 4-2-62 reduced to show the range safety implications; this reduction is done by a specific computer program available from the ATC Computer Applications Branch.
Records of previous tests of the same or closely related ammunition should be consulted before establishing the maximum permitted wind velocities for the test.
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.
The firing rate should be verified prior to the aetual impact test. 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. Fuzes are commonly used to initiate items such as a high explosive warhead and can also be used to create an incendiary effect.
