The weapon should be equipped the same as it will be used in service; flash hiders, muzzle brakes, etc. The contents of these documents are not copied into this TOP due to the volume of information; the documents must be studied to fill in the details of the procedures noted in the test methods below.
After the inspeetion, all the ammunition is fired and its veloeity is reeorded for eomparison to ammunition that has not been exposed to the thermal shock test.
Temperature of the test item is maintained throughout testing. A 30 minute waiting period is recommended before approaching the package.
This examination is primarily visual; dimensional checks, such as for overall length, weight, etc. The test machine is operated for 4-2602 minutes at 5 Hz 1. Conducting all three procedures will allow comparison of data across conditions and will greatly aid the development of an error budget. The procedures are not designed to test packaging or to test for the effects of long term underwater exposures.

It should be noted that itopp unclassified HEMP procedure may not be suitable for all evaluations. 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. The shooter should be provided with a test fixture, bench, or table to ltop loading and firing the weapons.
These gages are generally only used for acceptance procedures in manufacturing plants. The contact surface of the gage is curved to conform to the cartridge case.
Downloading the ammunition changes the velocity to spin ratio 4-2-6022 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. 4–2602 five round sample size should be fired under each required condition. Weapons will always be cleaned, inspected, and lubricated CIL at the end of each test procedure and before the start of another procedure the CIL at the end of a test procedure may serve as the CIL for the start of a subsequent test procedure based on the judgment of the test officer.
Partially empty packages should not be dropped or vibrated. Air sample collection and analysis is 4-2602 in general accordance with the National Institute for Occupational Safety and Health NIOSH Methodwhich includes cellulose ester filter collection, acid digestion, and analysis by inductively coupled plasma ICP spectroscopy. There are a variety of transducers and procedures for their use; the ammunition specifications must be consulted to determine the specific transducer and procedure to use.
Other targets, sueh as armor plate, fuze funetioning media, ete. Measure the obliquity of the plate as near as possible to the aetual projeetile strike targets are rarely perfeetly fiat and the obliquity will vary slightly aeross the surfaee.
Judgment must be used to determine what measurements are necessary; measurements critical for safety must always be checked. Clean itp interior surfaees of the ehamber by vacuuming or lightly damp mopping to remove any dust or firing residue. Evaluate the adequacy of human factors engineering of the test system using appropriate data-collection aids task lists, performance checklists, error reports, interview forms, rating scales, etc.
This test is done with unpackaged ammunition to simulate transportation as loose cargo. For weapons capable of being fired single shot, fire at target while checking sight alignment between each shot. The test officer must determine which document a given test is intended to address.
This test is done to determine the spatial distribution of ammunition debris projected from the weapon. These tests 4–602 be done to assure basic ammunition safety and functionality before extensive firings are done. Wind and temperature at the firing site should be reeorded for eaeh individual round.
If the item is not instrumented a minimum of ten items is required for each individual test. Screens may be constructed of any convenient material; fiberboard and light plywood are commonly used.
While pressures and velocities can be determined iitop separate tests, they should itpp recorded simultaneously if at all possible.
This proeedure requires that the distanee between the weapon and target be varied between eaeh shot. The cartridge case must retain its primer, but should otherwise not be loaded. Record projectile velocities for each shot.
Measure the location of the marks relative to the line of fire. The weapons and ammunition are subjected to the water spray continuously throughout the test and are fired from within the simulated rain field.
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.
The air pressure above the water is reduced by 50 KPa 7. The 4-2-62 for the first shot and following shots are determined from statistical tables and a computer program. Eor non-explosive ammunition it may be possible to open the packages for inspection. The critical requirements are as shown below: Zero each weapon in accordance with the weapon or sight manual; zero hand and itol weapons for m if manuals are not available.
If the ammunition is linked, inspect for cartridge alignment in the links, loose links, etc.
