4. REGULATORY REQUIREMENTS. The offeror/contractor is encouraged to use recovered materials to
the maximum extent practicable, in accordance with paragraph 23.403 of the Federal Acquisition
Regulation (FAR).
5. PRODUCT CONFORMANCE PROVISIONS
5.1 Product conformance. The products provided shall meet the salient characteristics of this CID,
conform to the producer’s 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 proof of such conformance.
5.2 Market acceptance. The following market acceptance criteria are necessary to document the quality
of the product to be provided under this CID:
a. The company producing the item must have been producing a product meeting the requirements
of this CID for at least 2 years.
b. The company must have sold 1,000 units meeting this CID in the commercial marketplace over
the past 2 years.
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 material. 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 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 on 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 (MPCAG)
evaluation program, CAGE code 58536 should be used.
7.4 Source of documents.

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 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 ASTM-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 analysis and research effort, this CID was coordinated
with the following manufacturers of commercial products. At the time of CID preparation and
coordination, these manufacturers were known to have commercial products that would meet the
requirements of this CID. (NOTE: This information should not be considered as a list of approved
