To be eligible for listing as an approved source of supply, a manufacturer shall be listed on the MIL-DTL-3933 Qualified Products Database for at least one part, or provide evidence that their parts have passed the qualification requirements of MIL-DTL-3933. 3
22、.8 Certificate of compliance. A certificate of compliance shall be required from manufacturers requesting to be an approved source of supply. 3.9 Recycled, recovered, or environmentally preferable materials. Recycled, recovered, or environmentally preferable materials should be used to the maximum e

VERIFICATION 4.1 Qualification inspection. Qualification inspection is not required. 4.2 Conformance ins
25、pection. 4.2.1 Inspection of product for delivery. Inspection of product for delivery shall consist of the group A inspection of MIL-DTL-3933. 5. PACKAGING 5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the contract or order (see 6.2). When packaging of
26、materiel is to be performed by DoD or in-house contractor personnel, these personnel need to contact the responsible packaging activity to ascertain packaging requirements. Packaging requirements are maintained by the Inventory Control Points packaging activities within the Military Service or Defen
27、se Agency, 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
28、a general or explanatory nature which may be helpful, but is not mandatory.) 6.1 Intended use. Attenuators conforming to this drawing are intended for use when military specifications do not exist and qualified military devices that will perform the required function are not available for OEM applic
29、ation. This drawing is intended exclusively to prevent the proliferation of unnecessary duplicate specifications, drawings, and stock catalog listings. When a military specification exists and the product covered by this drawing has been qualified for listing, this drawing becomes obsolete and will
30、not be used for new design. 6.2 Ordering data. The contract or purchase order should specify the following: a. Complete PIN (see 1.2). b. Requirements for delivery of one copy of the conformance inspection data or certificate of compliance that parts have passed conformance inspection with each ship
31、ment of parts by the manufacturer. c. Requirements for notification of change of product to the acquiring activity, if applicable. d. Requirements for packaging and packing. 6.3 Tin whisker growth. The use of alloys with tin content greater than 97 percent, by mass, may exhibit tin whisker growth pr
32、oblems 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. Alloy
33、s 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).
