It outlines test phases to be included and points out important features to be considered for each phase. The procedures apply to other types of proving ground tests of recoilless rifle ammunition as well as engineering tests. Approved for public release; distribution unlimited. TOP 22 September 4. The test proeedures apply to ammunition only; see TOP for test proeedures for recoilless rifles.
Numerous other documents relevant to testing Recoilless Rifles systems are referenced throughout the document. Unless specified otherwise the most recent version of the referenced document at the time of testing will be utilized.
Ammunition fired from recoilless rifle systems range from 66mm to mm. Projectiles typically do not have any sustained propulsion or flight control.
Service ammunition includes all ammunition likely to be used in combat; included are high explosive HEhigh explosive anti tank HEAThigh explosive dual purpose HEDPtandem-warheads, illumination, flechettes, enhanced otop and smoke, etc. These documents must be thoroughly reviewed to properly conduct their subject tests. Many of the referenced documents assume test items much larger than typical recoilless rifle ammunition; this TOP gives information for tailoring such procedures to be more suitable for recoilless rifle munitions.
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. Actual requirements and criteria must come from requirements documents, contractual obligations.
The lists below show specialized items that are used in the test procedures. Additional information is contained in the individual test procedures since requirements for accuracy and precision of a given measurement may vary among the procedures. Standard equipment common to most technical organizations is not listed; however, the test officer must assure that the specific requirements 4-2-6602 each procedure are met by whatever equipment or instrumentation is used.
Superscript numbers correspond to those in Appendix A, References. Test stands Must safely restrain the weapon, allow remote firing, and assure reprodueible results. Ground mounts Ballistie Pendulum, aeeuraey, Blast Overpressure, ete. Speeifie to the test support weapon. Support ammunition Similarity to the test ammunition to permit eheekout of test setups, instrumentation, ete. Referenee ammunition Assessed for ehamber pressure and veloeity.
Targets Physieal or eleetronie with iyop eapability of reeording the X and Y eoordinates of eaeh projeetile passing through the plane of the target; speeifie aeeuraey requirements will vary among the various tests, but in all eases the aeeuraey and preeision must be suffieient to address the eriteria for the partieular test 4–2602 done.
Other targets, sueh as armor plate, fuze funetioning media, ete. Pressure barrels Barrels ehambered for the test eartridge and ported for eleetronie or erusher type pressure gages. Review the Safety Assessment Report and all instructional material issued with the test item by the developer and manufacturer, as well as reports of previous tests conducted on the same model or closely related item.
Review the Safety Release if one exists.
The SEP will document the methodology and data requirements and any unique test and evaluation methodologies itoo those stipulated in this TOP. For non-acquisition projects, the customers test requirements will be followed to the extent possible, based on information in the Request for Test Services RETS and direct communication with the customer. Assemble information on the physical characteristics of the test item, its method of operation, maintenance requirements, and expected modes and areas of deployment.
Review the information to determine any effect on testing procedures such as environmental impact, temperature requirements, handling precautions, etc. Based on the above information, plan a eomprehensive testing program to verify that the test item satisfies minimum design and eonstruetion requirements for safe field deployment and ean also provide performanee data that ean satisfy user requirements.
Tests appropriate for forming a test program are deseribed in paragraph 4. For some test programs, these proeedures will need to be expanded or speeial test eonsiderations will be required, while in many other eases, not all proeedures eontained in this TOP will be applieable. The number of test samples needed depends heavily on the type of test and what the test results are expeeted to aeeomplish or support.
For example, a Teehnieal Feasibility Test may only 4-2-6022 a small sample size whereas an Engineering Development Test designed to support a Milestone Itpo deeision would require a mueh larger sample size see DTC Pamphlet for definitions of test types and milestones. Although test eeonomy must also be eonsidered, the sample size must be suffieient to provide reasonable assuranee that eomparison of test results against requirements will be meaningful.
Documents such as the SEP or CDD should be reviewed for required sample sizes or for confidence levels from which sample sizes can be derived. Consult with a statistician or independent evaluator if needed to resolve sample sizes against test criteria.
Consideration must be given to the possibility of combining data from separate test procedures to effectively increase sample sizes and confidence in results.
All sample size decisions should be coordinated with the ATEC System Team Eead or assigned independent evaluation agency before making a final determination. 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 sample size of ammunition for safety testing is based on reasonable and successful prior development testing and observations.
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. A larger sample size must be used when marginal performance or randomly encountered problems are expected and are to be measured with some degree of confidence. Conduct safety tests and high-risk tests first to provide an early indication of suitability.
This TOP does not include a recommended sequence for the complete series of subtests due to the many variations of ammunition and weapon designs and due to facility considerations such as the scheduling of ranges and laboratory support.
FR/GE/UK/US INTERNATIONAL TEST OPERATIONS PROCEDURE (ITOP) 4-2-602 ROUGH HANDLING TESTS
Ammunition should not be used for multiple tests as conditioning in one environment might lead to a failure in another. The safety and suitability of recoilless rifle ammunition is interrelated with the weapons with which it is used. Care must be taken during testing to assure that the distinction is made between inherent ammunition functioning and weapon induced problems. Weapons will be maintained in accordance with technical manuals, if available.
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 itlp on the judgment of the test officer.
More detailed maintenance will be done as needed. Weapon lubricants, gas port settings, etc. All maintenance actions will be recorded. Weapon maintenance procedures should be coordinated with the ATEC System Team lead or assigned independent evaluation agency, the Program Manager and weapon manufacturer prior to the initiation of testing. Test ammunition must be fired to determine its performance in its itoo weapons.
Review all instructional material issued by the manufacturer, contractor, or government, as well as reports of previous similar tests conducted on the same type or test item; familiarize all test personnel with the contents of such documents.
Keep these documents readily available for reference.

Request that New Equipment Training is provided for personnel that will be conducting the testing. The limited amount ittop test ammunition should be preserved for actual testing.
Support ammunition similar to the test ammunition should be provided if at all possible.
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.
Support ammunition is also used to verify proper function of the support weapons. Some support ammunition may be used for direct comparison with the test ammunition in comparative tests such as toxic fumes, muzzle flash, tracer intensity, etc. The support ammunition used must be fully identified; record the full nomenclature. The test ammunition should be kept in its original shipping and storage containers until immediately before use.
Make a general visual examination of the ammunition after it is removed from its packaging for a test; record any discrepancies such as shipping damage, evidence of improper storage, etc. Use the guidelines from paragraph ittop.
Save some of the original shipping containers and packing materials; they are often needed to repack 4-2-60 after various rough handling and environmental tests. Basic tests are common across the different types of recoilless rifle ammunition.
These tests should be done to assure basic ammunition safety and functionality before extensive firings are done. The iyop for some of these tests may be available from the manufacturer or from other government agencies; in such a case it may not be necessary to repeat the test. Cartridges received for test are examined for damage and defects. This examination is primarily visual; dimensional checks, such as for overall length, weight, etc. The inspections must be carried out in an approved facility by personnel itkp in ammunition handling.
Inspect the exterior of all packages for physical damage, water stains, or any other evidence of improper storage or handling. Record how the packages are marked. Note how otop cartridges are packed, recording the type of container, overwrap if anyand number of cartridges per container.
Open one container and any interior containers to expose the test ammunition. Record the type and condition of any interior packing material, padding, or spacers. Inspect the interior of the container for foreign material, loose propellant, evidence of moisture, and general cleanliness.
Record the markings of any interior containers such as bandoliers, cardboard boxes, loaded magazines, etc. Thoroughly inspect each cartridge in the opened package. Use the Military Specification for the test item as a guide for determining and reporting any defects found in the inspection. The list below indicates many of the things to look for during the inspection.
It is not feasible to check all possible physical measurements of a complete round of ammunition. Judgment must be used to determine what measurements are necessary; measurements critical for safety must always be checked.
The dimensions and weights shown below should be recorded from otop minimum of ten rounds. Dimensions and weights as recorded. Recoilless rifle ammunition is useful only to the degree that Soldiers can use it effectively and safely. Human factors tests can be done informally by accumulating data throughout all testing, or they can be done formally by a utop dedicated 4-2-60 to human factors.
Typical areas of interest are unpacking the ammunition, handling of packed and tiop ammunition, clarity of identification markings, ease of loading and firing in various positions, and signature effects such as smoke, muzzle iotp, noise and recoil.
Use the task checklists for individual weapons and for crew served weapons contained in TOPPart II, for guidance. For example, provide military issue cold weather gloves to weapon operators during extreme cold functioning tests and observe for the ease of unpacking the ammunition and loading a weapon.
