For acquisition purposes, the packaging requirements shall be as specified in the contract or order (see 6.2). When packaging of materie

28、l is to be performed by DoD or in-house contractor personnel, these personnel need to contact the responsible packaging activity to ascertain packaging requirements.

29、ncy, or within the military services system commands. Packaging data retrieval is available from the managing 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 gene

30、ral or explanatory nature that may be helpful, but is not mandatory.) 6.1 Intended use. Resistors are intended for use in dc amplifiers, voltmeter multipliers, electronic computers, meters, and laboratory test equipment.

Complete PIN (see 1.2). b. Requirements for delivery: One copy of the conformance inspection data that parts h

32、ave passed conformance inspection, with each shipment of parts by the manufacturer. c. Bulk packaging requirements (see 5.1). d. Whether the manufacturer performs the group A, dc resistance sample test data (see 4.3.2). e. Whether the manufacturer performs the group B inspection or provides a certif

33、icate of compliance (see 4.3.3.1). 6.3 Tin whisker growth. The use of alloys with tin content greater than 97 percent, by mass, may exhibit tin whisker growth problems after manufacture. Tin whiskers may occur anytime from a day to years after manufacture and can develop under typical operating cond

34、itions, 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 inhibit the growth of tin whiskers. For additional information on this matter, refer to ASTM-B5

35、45 (Standard Specification for Electrodeposited Coatings of Tin). 6.4 User of record.
