2、nd is available for use by all Departments and Agencies of the Department of Defense. 1. SCOPE 1.1 Scope. This specification covers the material, requirements, examinations, tests and packaging for a family of blow molded plastic divider racks used for restraining loose: unpalletized 155mm projectil
3、es; unpalletized 8 inch projectiles; or unpalletized, unboxed 120mm mortar rounds contained in fiber tubes during on-vehicle storage and transport (see 6.1). The rack consists of specifically designed plastic dividers that, when assembled, will restrain any conventional projectiles of the 155mm or 8
4、 inch family, or all 120mm mortar rounds in fiber tubes (see 6.4). The loaded racks are restrained in a tactical transport vehicle by means of a cargo tiedown strap(s) applied in an approved manner. The combinations for 155mm or 8 inch are referred to as Loose Projectile Restraint System (LPRS). The
5、 combination for 120mm mortar is referred to as Loose Round Restraint System (LRRS). 2. APPLICABLE DOCUMENTS 2.1 Government documents. 2.1.1 Specifications, standards, and handbooks.

In the event of a conflict between the text of this document and the references cited herein, the text of this document takes precedence. Nothing in this document, however, supersedes applicable laws and regulations unless a specif
22、ic exemption has been obtained. 3. REQUIREMENTS 3.1 Materials. The materials used in the manufacture of the applicable divider(s), ammunition, shall be as specified on Dwg AC200000408. Certification of compliance shall be provided by the contractor. 3.2 Dividers. Parts and assemblies shall comply wi
23、th all requirements specified on the applicable drawings and with all requirements specified in the applicable specifications. 3.2.1 Flatness. When new and in a relaxed position laid flat on a side, the sides of a divider shall be straight within 1/8 inch from a 24 inch straight edge placed at any l
24、ocation other than over the stacking lugs. 3.2.2 Weld cones. Weld cones shall be homogeneously welded together at the plane of the mold parting line to provide maximum strength to the divider as intended by design. 3.2.3 Drainaue holes. Drainage will be provided for any moisture accumulated within t
25、he divider interior when the dividers are assembled on either edge. matching any of the following colors of Federal Standard 595: -34052, -34079, -34086, -34087, -34096, or -34102. To retard sun degradation, ultraviolet stabilizer shall be added into the color concentrate. Certification shall be pro
26、vided by the contractor to assure that the ultraviolet stabilizer added into the color concentrate consists of 0.3 percent Tinuvin 770 and 0.05 percent Igranox 1076 based on a 4.0 percent color letdown. 3.2.4 Color. The color of the divider shall be olive drab 3.2.5 Stackina luqs. Dividers when laid
27、 flat and stacked, will nest on their stacking lugs without space between dividers. This nesting is required in any flat position, i.e., open slots pointing in the same direction or alternating directions, NSN up or down. The vertical sides of the stack shall align within + 1/8 inch. Different lengt
28、hs of dividers are not intermixed for this requirement (see 4.5.6). 5 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-R-48664B = 9999906 1856555 265 MIL-R-48664B (AR) 3.3 Performance test. The following defects shall not be permitted on the teste
29、d assemblies: a. Failure of the rack by deforming, splitting or breaking, which allows the dividers to disengage and spill the projectiles/rounds during the performance tests. b. Separating of the parting line seam more than 2.5 inches along the top edge of the divider in contact with the projectile
30、s/rounds. This failure shall not result in a collapse of the divider walls below the next structural stiffener; either handle, hand grip or weld cone. c. Any breaking or cracking of the rack other than at the parting line seam (see 3.3.b.) during the performance tests. Punctures, abrasions and wear
31、though caused by the restraint strap metal parts or projectile grommets are not counted as a failure, providing such wear does not lead to functional failure of the dividers or rack assembly. d. Excessive bending of the short sections at the corners of an assembled rack loaded with projectiles/round
32、s and restrained to a vehicle side wall by a cargo strap on three sides of the rack per TM 9-2590-210-10 or other applicable restraint publication. Excessive bending is deformation which allows the restraint strap(s) to disengage from the strap slot allowing the rack assembly to radically shift or u
33、pset during the performance tests (see 4.5.1.2.). e. Deformation of a divider which interferes with ease of disassembly (see 4.5.5). f. Failure of disassembled dividers to be reassembled into a load bearing rack for successful continuation of the performance test. 3.4 Divider markinas. The divider d
34、esign shall include a thirteen digit (plus three dashes) National Stock Number (NSN) molded in a recessed manner in each divider in 3/8 inch characters by 1/16 inch deep on one side only. The divider design shall include a material designator code and year (last 2 digits) the divider was manufacture
35、d molded in a recessed manner in each divider in 1/4 characters by 1/32 deep on one side only. The divider design shall include the contract number molded in a recessed manner in 6 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-R-48bb4B = 9Ob 18

See applicable part drawing for location of markings. 3.5 Ease of assembly and disassembly. The divider slots shall be so c
37、onstructed to permit ease of assembly and disassembly yet the assembled divider rack must be rigid enough to maintain its original configuration while loaded. The loaded rack configuration is evaluated by a performance test (see 4.5.1) and extreme operating temperature tests (see 4.5.4). Ease of dis
38、assembly is tested as specified in 4.5.5. 3.6 Extreme operatinq temperatures. The rack, ammunition, must restrain the applicable ammunition load at temperatures from minus 60 degrees Fahrenheit to plus 145 degrees Fahrenheit (see 4.5.4), as evidenced by meeting the performance test requirements of 3
39、.3. 3.7 Process controls. The contractors quality program plan or detailed inspection plan shall include documented process controls which detail the specific procedures involved in the manufacture of the plastic dividers. These documented process controls shall be submitted to the contracting offic
40、er for review and approval by the cognizant technical agency (CTA) in accordance with the approved DID specified on the Contract Data Requirements List (CRDL) in the contract (see 6.3). The contractor shall not initiate production without written approval from the contracting officer. Once approved,
41、 the contractor shall not change the process without written approval from the contracting officer. The documented process controls shall include the following information as a minimum: a. Item nomenclature b. Applicable component (divider) c. List of applicable drawings and specifications d. List o
