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

    21、le 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 managing

    22、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 general or explanatory nature that may be helpful, but is not mandatory.) 6.1 Intended use. The intended use specifi

    23、ed in MIL-PRF-12934 will be 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. If not otherwise specified (see 2.1), the versions of the individual docu

    24、ments referenced will be those in effect on the date of release of the solicitation.). c. Packaging instructions (see 5.1). 6.3 PIN. This specification requires a PIN that describes technology and appropriate references to associated documents (see 1.2 and 3.1). 6.4 Tin whisker growth. The use of al

    25、loys 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 conditions, on products that use such materials. Conformal coatings applied

    26、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-B545 (Standard Specification for Electrodeposited Coatings of Tin). 6.5 Ch

    27、anges from previous issue. The margins of this specification are marked with vertical lines to indicate where changes from the previous issue were made. This was done as a convenience only and the Government assumes no liability whatsoever for any inaccuracies in these notations. Bidders and contrac

    28、tors are cautioned to evaluate the requirements of this document based on the entire content irrespective of the marginal notations and relationship to the last previous issue.
