2.1.1. Levels of preservation and packaging and the levels of packing to be applied selectively are defined in Military Specification 116 and Military Standard 2073 and are mandatory for use. Selection of levels shall be in accordance with the level selection chart in Military Standard 2073 and in Appendix A of this NPR.
2.1.2. Selection of the levels of packaging and packing to be applied shall be the responsibility of the Center Transportation Officer unless levels are specified by the procuring activity. Selection shall depend on the modes of transport, environmental control, conditions, and length of storage, and the anticipated requirements for redistribution.
2.1.3. When Level A or Level B packaging and/or packing is selected, the protective process, materials, and containers shall be in accordance with the requirements of Military Standard 2073. National Aerospace Standards 850 and 851 may be considered for Level B or Level C application where the standard meets the requirements for that level.
For those items possessing characteristics requiring special design packaging as defined in Appendix A, the contractor shall develop the necessary designs, maintain packaging engineering data in sufficient detail to permit necessary review, and implement the packaging specified therein. Prior to developing a newly designed container, maximum effort shall be made to use container designs or containers from those already available commercially or from Government inventories (see paragraphs 2.9. and 2.10.). Specifically identified special design packaging may be screened through the Air Force Container Design Retrieval System (hereinafter called the System). Candidates for screening through the System shall be selected on the basis of cost, schedule, and complexity of design and fabrication. Unless otherwise specified, search requests through the System should be sent directly to Armament Development and Test Center, United States Air Force Systems Command, Eglin Air Force Base, Florida 32542. (See Figure 1 for the Container Design Retrieval System Search Request Form.) Each request will establish a desired response date. Pending timely response, the Transportation Officer shall withhold package container development. When specified by the procuring activity, new design data and engineering drawings with specifications in accordance with Military Standard 1510, paragraphs 4.1.2 and 4.1.3, will be submitted as stated in the Contract Data Requirements List.
For purposes of this NPR, unless otherwise specified by the procuring activity, package engineering documentation shall be required only for special design packaging. Contractor documentation forms may be used unless otherwise specified in the contract. Submission and approval shall be in accordance with the Contract Data Requirements List or as otherwise authorized in the contract or by written direction of the contracting officer. Military Standard 2073 may be used for guidance.
2.4.1. The preservation, packaging, packing, and shipping techniques applied shall ensure protection of the contained item against the natural and induced environments to which it may be subjected. Analysis of these hazards is essential prior to item design and development of the packaging and shipping techniques to be applied. The contractor shall ensure that design engineering provides item fragility, engineering drawings, and sensitivity data to packaging engineering, line packaging, and transportation personnel.
2.4.2. The contractor's packaging and transportation engineers and/or technicians shall participate in equipment design efforts from the earliest stages. They shall identify the ground handling, transport and storage environment requirements, including protection from contingency or emergency environments where the environmental analysis indicates that facility/carrier protection is more practical, reliable, or cost effective than providing the same protection by packaging and packing design; prepare or identify testing programs; prepare packaging and transportation data for use in management's configuration documents; and perform such other functions in the design effort as may be necessary or proper.
2.4.3. The environmental analysis shall include tradeoff considerations of the class of shipping and handling (probability of a loss, cost and schedule impact of loss, and cost of facility and carrier protection) versus cost of packaging and packing protection. The following phases shall be considered:
2.4.3.1. Inplant storage, handling, and local transportation conditions and environments, both normally anticipated and contingency due to such emergencies as natural disasters, fires, spillage, and other accidents.
2.4.3.2. Intransit modes, normal and contingency environments.
2.4.3.3. Receiving, redistribution, handling, and storage conditions at the destination installation, range, test or launch facility including normal and contingency environments.
2.4.3.4. General guidance on transportation environments is available in the following documents: a) Marshall Space Flight Center Report 1262, Design Criteria for Shock and Vibration; and b) Military Standardization Handbook 304, Package Cushioning Design. (Also see Military Standard 810 and Federal Standard No. 101.)
2.5.1. The packaging and packing of hazardous materials shall be in accordance with the General Provisions and the Safety Provisions of the contract and this NPR. Provisions of NPD 6000 and NPR 6200 pertaining to the shipment of hazardous materials shall be complied with as applicable. In addition, the transportation of these materials must be in compliance with applicable State and municipal rules and regulations. All hazardous materials offered for military airlift shall also be prepared in accordance with the requirements of Air Force Logistics Manual 24-204.
2.5.2. All items that are subject to ignition or detonation by electrostatic discharge and which are to be packed in bags or wraps manufactured from Military Barrier Material 22191, 121, 131, or other static-generating materials shall be wrapped individually in antistatic material, meeting the requirements of Military Barrier Material 81705. Antistatic packaging material shall, in all cases, be intimate to the item.
2.5.2.1. The following notation, shall be affixed to each unit package:
WARNING
CONTENTS SUBJECT TO IGNITION OR DETONATION BY ELECTROSTATIC DISCHARGE. GROUND INNER ANTISTATIC WRAPPING BEFORE AND DURING REMOVAL FROM THIS PACKAGE.
NOTE: THIS WARNING DOES NOT TAKE PRECEDENCE OVER OR SERVE IN LIEU OF REQUIREMENTS SPECIFIED IN APPLICABLE REGULATIONS AND TARIFFS.
2.5.2.2. Where considerations of precision, cleanliness, flammability, or compatibility with propellants preclude the use of antistatic material meeting Military Barrier Material 81705, Type II, contractors are authorized to use commercially available antistatic materials. Preapproval for such use must be granted by the Contracting Officer or the Center Transportation Officer.
2.5.3. In addition to the regulations cited in paragraph 2.5.1, further requirements regarding the packaging and transport of radioactive materials are contained in Title 10, Code of Federal Regulations, and in Title 14, Code of Federal Regulations.
2.6.1. Many electronic devices such as thin or thick film resistors, semiconductors, field effect transistors, or circuitry containing any of these can be degraded by static electricity. The contractor will assure that design engineering identifies such items and provides the essential precautions to all inplant handling and packaging personnel.
2.6.2. Items shall be packaged in accordance with paragraph 2.5. Each package shall bear a label warning that the contents can be destroyed by static electricity and should be handled only by personnel instructed in the necessary precautions.
Preservation, packaging, and packing of kits (parts and modifications) shall be in accordance with Military Standard 2073, Appendix D.
Accomplished packs shall be as simple as possible and of minimum tare weight and cube, consistent with the protection required. Consolidation containers and pallets shall be properly used to reduce multiple handling; however, items bearing the NASA Critical Item Label (NASA Form 1368) shall not be commingled with noncritical items in any container. When the gross weight of the individual pack or consolidation exceeds 100 pounds or when the package cube exceeds 10 cubic feet, use of skids or pallets should be considered.
2.9.1. Reusable containers are those that are designed to provide adequate protection when reused for return shipments and/or throughout several shipping cycles or sequences. Reusable containers shall be considered for all items that require periodic shipments to and return from repair activities and where adequate provisions to control the containers make reuse economical. The quantities of reusable containers authorized shall be the minimum essential to meet anticipated pipeline needs. The contractor shall identify reusable containers and provide storage to assure their maintenance in a serviceable condition for use. The container specifications issued by the International Air Transport Association merit consideration for application to air shipping cycles.
2.9.2. Existing reusable containers available commercially or from Government or contractor inventories shall be used to reduce package design and fabrication costs. Modification of existing containers and container designs shall be considered when this is a cost-effective approach.
2.9.3. Multiapplication containers are especially useful for return of repairables since each size and type is suitable for shipment of a large number of different items within certain limits of size, weight, and fragility. These containers are described in Military Standard 2073, Appendix E. Use of this type of container is authorized for Level A and B applications where the multiapplication containers will provide equivalent protection to the contained item.
Packaging materials should be considered for reuse to the maximum extent practicable. The determination for reuse should be based on the quality and condition of the material, the economics of storage and handling of the used material, and the incidence of usage anticipated.
Disassembly of major components to facilitate packaging, or to provide more effective procedures, is permissible unless otherwise specified. Normally, components shall remain assembled if previous inspection or test acceptances are invalidated. Efforts should be made to secure assembly hardware to one of the mating parts when disassembly is accomplished.
When necessary to facilitate reassembly or repackaging, removed parts shall be matchmarked. Tags used for matchmarking shall conform to Type A of Specification UU-T-81. Tags shall be oversprayed with a material conforming to Specification TT-V-121 or MIL-P-16108 and then secured to the item so as to offer no interference with reassembly.
2.13.1. Markings on unit packages, intermediate packages, and exterior shipping containers shall be in accordance with the applicable requirements of Military Standard 2073 and this NPR.
2.13.2. Items designated as Class I, Class II, or Class III, in accordance with Appendix A, should normally bear an appropriate NASA Critical Item Label (NASA Form 1368). The label shall be affixed to each side, end, and top of the container. Labels should not interfere with other required markings. Drums shall be marked with a label on the top and on opposite sides.
2.13.3. Shelf life terminal and preservation expiration dates shall be identified by marking, by tagging, or in log books as specified by design engineering requirements.
2.13.4. Marking and labeling of hazardous materials shall be in accordance with appropriate regulations as cited in paragraph 2.5 and with other contractual provisions.
2.14.1. Testing of packages, packing methods, and materials shall be in accordance with design engineering requirements. When specific guidance is not provided, tests shall be performed as specified in Appendix B of Military Standard 2073. In all instances, only standardized packaging testing techniques will be utilized.
2.14.2. Shipping contractors shall ensure that all special testing data is furnished, as required by the contract.
2.14.3. Preproduction tests shall be performed in accordance with the design requirements of the contract. The necessity for such testing will be determined by considering the following factors:
2.14.3.1. The contractor has data or other evidence to indicate that prior successful tests were conducted and are accepted by the contracting officer as being equivalent to those now being proposed.
2.14.3.2. The packaged item has been subjected to similar tests as a part of other testing programs.
2.14.3.3. The container for a specific item of equipment is developed under an end-item specification, with engineering and testing approval through configuration management procedures and reviews.
2.14.3.4. Detailed packaging instructions are imposed by the procuring activity.
2.14.4. Provisions for the testing of hoisting and material handling equipment shall be performed as required.
