When packaging of materiel is to be performed by DoD or in-house contractor personnel, these personnel need to contact the

28、responsible packaging activity to ascertain packaging requirements. Packaging requirements are maintained by the Inventory Control Points packaging activity within the Military Service or Defense Agency, or within the military services system commands. Packaging data retrieval is available from the

29、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 general or explanatory nature that may be helpful, but not mandatory.) 6.1 Intended use. The notes specif

30、ied in MIL-PRF-39035 are applicable to this specification. 6.2 Acquisition requirements. Acquisition documents must specify the following: a. Title, number, and date of this specification, and the complete PIN (see 1.2). b. Unless otherwise specified (see 2.1), the versions of the individual documen

31、ts referenced will be those in effect on the date of release of the solicitation. c. Packaging instructions (see 5.1). 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 anytim

32、e 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 inhibit the

33、 growth of tin whiskers. For additional information on this matter, refer to ASTM-B545 (Standard Specification for Electrodeposited Coatings of Tin). 6.4 Changes from previous issue. The margins of this specification are marked with vertical lines to indicate where changes from the previous issue we

34、re made. This was done as a convenience only and the Government assumes no liability whatsoever for any inaccuracies in these notations. Bidders and contractors are cautioned to evaluate the requirements of this document based on the entire content irrespective of the marginal notations and relation

35、ship to the last previous issue.
