DEVELOPMENT OF MILITARY PACKAGING REQUIREMENTSFOR KITS (PARTS AND MODIFICATION)

D.1 SCOPE. This appendix covers the development of military packaging for parts kits andmodification kits (see 4.7). This appendix is a mandatory part of this standard. The informationcontained herein is intended for compliance, as applicable.

D.2 APPLICABLE DOCUMENTS.

This section is not applicable to this appendix.

D.3 PRESERVATION. Military preservation shall be applied to all items within the kits,including Government furnished property (GFP) or spare parts (to be assembled into kits).Methods of preservation shall be determined in accordance with Appendix A and procedurescontained herein.

D.3.1 Consolidation of different items within a method of preservation. Hazardous itemswill be packaged in the same container only if the commodities are compatible. Items of differentphysical characteristics may be consolidated within the same method of preservation if all of thefollowing requirements are met:

a. The items to be consolidated are all part of the same individual kit, identified by asingle NSN.

b. The method of preservation shall afford adequate protection to the most critical itemcontained therein.

c. The area of the protective barrier shall not be increased by the addition of noncriticalitems to the extent that the package life will be shortened due to the increase in watervapor transmission or that a substantial increase in desiccant will be required.

d. Items of a delicate nature shall not be subjected to damage from rugged itemscontained within the same package.

e. Noncritical items of odd shapes or having sharp protrusions will not damageprotective barriers.

f. Items of dissimilar metals subject to damage from electrolytic action shall be insulatedwith suitable material to prevent forming of galvanic cells.

g. Electromagnetic and electrostatic sensitive items shall be provided protection fromdegradation with electrostatic or electromagnetic protective materials conforming tomilitary specifications.

D.3.2 Application of preservative compounds or oils.

D.3.2.1 Kits procured for oxygen equipment. No preservative compound or oil shall beapplied to any item that may come into contact with oxygen.

D.3.2.2 Preservation procedures. All items are to be thoroughly cleaned and dried inaccordance with 5.2.1 before application of preservative compounds or oils. In no instance shall apreservative compound or oil be applied over an operational grease or oil.

D.3.2.3 Items susceptible to corrosion (iron, steel, magnesium, etc.). No preservativecompound or oil will be applied if application would be harmful to the item. Preservativecompounds are preferred; however, preservative oils may be used when compounds are difficultto remove, or are not feasible due to size, configuration or application of the item.

D.4 UNIT PRESERVATION

D.4.1 Physical protection. When kit items require physical protection, cushioning, wrapsand containers of the minimum size and weight necessary to afford such protection shall beapplied.

D.4.2 Segregation of items within packs. Care will be used to ensure that items whichwould be difficult to identify by visual observation are kept segregated and individually identified.Also, it is desirable to segregate components of two related repairable assemblies within the kit.For example, in a kit for an air-to-air missile, components for the arming and fusing subsystemshall not be intermingled with components for the guidance subsystem. Segregation of itemswithin a kit shall be accomplished by wraps, bags, boxes, dividers, container separations, tubes,skin or blister packs or other approved means.

D.4.3 Skin packaging. When skin packaging is used for kits, provisions shall beincorporated into the design layout for minimizing the size of the skin pack. This may beaccomplished by folding, slotting, scoring, creasing, or perforating the substrate.

D.4.3.1 Skin packaging metals. Segregated metal items coated with preservative shall bewrapped with a greaseproof material unless the skin packaging material, ink, and backing board incontact with the item are noncorrosive and greaseproof. Bare metal items not coated with a

APPENDIX D

95

preservative compound shall be wrapped with a neutral material unless the skin packagingmaterial, ink, and backing board in contact with the item are noncorrosive.

D.4.3.2 Skin packaging shims or gaskets. Kit items such as thin shims or paper gaskets,that cannot be removed from the skin pack without damage to the item shall be placed in a bag orother suitable protective media prior to film application to provide ease of removal.

D.5 PACKING AND MARKING OF KITS. Packing and marking requirements shall be inaccordance with 5.3 and 5.5, respectively.
