15、nformance. The products provided shall meet the salient characteristics of this CID, conform to the producers own drawings, specifications, standards, and quality assurance practices, and be the same product offered for sale in the commercial market. The Government reserves the right to require proo
16、f of such conformance. 6. PACKAGING. Preservation, packing, and marking shall be as specified in the contract or order. 7. NOTES. 7.1 PIN. The PIN should be used for Government purposes to buy commercial products to this CID. See section 2 for PIN format example. 7.2 Environmentally preferable mater
17、ial. Environmentally preferable materials should be used to the maximum extent possible to meet the requirements of this specification. As of the dating of this document, the U.S. Environmentally Protection Agency (EPA) is focusing efforts on reducing 31 priority chemicals. The list of chemicals is
18、available on their website at http:/www.epa.gov/epaoswer/hazwaste/minimize/chemlist.htm. Further information is available at the following EPA site: http:/www.epa.gov/epaoswer/hazwaste/minimize/. Included in the EPA list of 31 priority chemicals are cadmium, lead, and mercury. Use of the materials o
19、n the list should be minimized or eliminated unless needed to meet the requirements specified herein (see Section 3). 7.3 Commercial and Government Entity (CAGE) code. For ordering purposes, inventory control, and submission of these inductors to DSCC under the Military Parts Control Advisory Group
20、(MPCAG) evaluation program, CAGE code 58536 should be used. 7.4 Source of documents.

21、al Street, NW, Washington D.C. 20401.) 7.5 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
22、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 growth of tin whiskers. For additional information on this matter, refer to AST
23、M-B545 (Standard Specification for Electrodeposited Coatings of Tin). 7.6 Ordering data. The contract or order should specify the following: a. CID document number, revision, and CID PIN. b. Product conformance provisions. c. Packaging requirements. 7.7 Commercial products. As part of the market ana
24、lysis and research effort, this CID was coordinated with the following manufacturer of commercial products. At the time of CID preparation and coordination, this manufacturer was known to have commercial products that would meet the requirements of this CID. (NOTE: This information should not be con
