36、. PACKAGING 5.1 Packaging requirements. For acquisition purposes, the packaging requirements shall be as specified in the contract or order (see 6.2). When actual packaging of materiel is to be performed by DoD or in-house contractor personnel, these personnel need to contact the responsible packagi

37、ng activity to ascertain requisite packaging requirements. Packaging requirements are maintained by the Inventory Control Points packaging activity within the Military Department or Defense Agency, or within the military services system commands. Packaging data retrieval is available from the managi

38、ng Military Departments or Defense Agencys automated packaging files, CD-ROM products, or by contacting the responsible packaging activity. 6. NOTES (This section contains information of a general or explanatory nature that may be helpful, but is not mandatory.) 6.1 Intended use. Filters conforming

39、to this drawing are intended for use when military specifications do not exist and qualified military devices that will perform the required function are not available for OEM application. This drawing is intended exclusively to prevent the proliferation of unnecessary duplicate specifications, draw

40、ings, and stock catalog listings. When a military specification exists and the product covered by this drawing has been qualified for listing on QPL-28861, this drawing becomes obsolete and will not be used for new design. The QPL-28861 product shall be the preferred item for all applications. 6.2 A

41、cquisition data. The acquisition document should specify the following: a. Complete PIN (see 1.2). b. Requirements for delivery of one copy of the conformance inspection data with each shipment of parts by the manufacturer. c. Whether the manufacturer performs the group B tests or provides certifica

42、tion of compliance with group B requirements. d. Requirements for notification of change of product to acquiring activity, if applicable. e. Requirements for packaging and packing. 6.3 Soldering temperature. Caution: These devices should not be exposed to soldering temperatures exceeding 300C. Expos

43、ure time to soldering temperature of 300C should not exceed one minute. 6.4 Pure tin prohibition. Pure tin is prohibited since it may result in tin whisker growth. The use of alloys with tin content greater than 97 percent may exhibit tin whisker growth problems after manufacture. Tin whiskers may o

44、ccur anytime from a day to years after manufacture and can develop under typical operating conditions on products that use such materials. Conformal coatings applied over top of a whisker-prone surface will not prevent the formation of tin whiskers. Alloys of 3 percent lead, by mass, have shown to i

45、nhibit the growth of tin whiskers. For additional information on this matter, refer to ASTM-B545 (Standard Specification for Electrodeposited Coating of Tin). 6.5 Users of record. Military and industry users of his drawing should inform DLA Land and Maritime when a system application requires config

46、uration control. DLA Land and Maritime-VAT will maintain a record of users and this list will be used for coordination and distribution of changes to this drawing. Coordination of this document for future revisions is coordinated only with the approved sources of supply and the users of record of th

47、is document. Requests to be added as a recorded user of this drawing should be in writing to: DLA Land and Maritime-VAT, PO Box 3990, Columbus, OH 43218-3990, by e-mail to capacitorfilterdla.mil, or by telephone (614) 692-4709 or facsimile (614) 693-1644. 6.6 Replaceability. Filters covered by this

48、drawing will replace the same commercial device covered by contractor-prepared specification or drawing.
