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 was previously listed, or provide evidence that their parts have
21、 passed the group A inspections, Screening (when applicable) and material specified in MIL-DTL-3933. 3.8 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 m
22、aterials. Recycled, recovered, or environmentally preferable materials should be used to the maximum extent possible provided that the material meets or exceeds the operational and maintenance requirements, and promotes economically advantageous life cycle costs. 3.10 Workmanship. The attenuator sha
23、ll be uniform in quality and free from any defects that will affect life, serviceability, or appearance. 4. VERIFICATION 4.1 Qualification inspection. Qualification inspection is not required. 4.2 Conformance inspection. 4.2.1 Inspection of product for delivery. For N level product, inspection of pr
24、oduct for delivery shall consist of the group A inspection of MIL-DTL-3933. For S level product, inspection of product for delivery shall consist of screening and the group A inspection of MIL-DTL-3933. 5. PACKAGING 5.1 Packaging. For acquisition purposes, the packaging requirements shall be as spec
25、ified in the contract or order (see 6.2). When packaging of 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 Poin
26、ts packaging activities within the Military Service or Defense 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 packagi
27、ng activity.

NOTES (This section contains information of a general or explanatory nature which may be helpf
28、ul, 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 application. This drawing is intended exclusively to pre
29、vent 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 not be used for new design. 6.2 Ordering data. The
30、 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 shipment of parts by the manufacturer. c. Requirements
31、 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 problems after manufacture. Tin whiskers may occur a
32、nytime 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 inhibi
33、t the growth of tin whiskers. For additional information on this matter, refer to ASTM-B545 (Standard Specification for Electrodeposited Coatings of Tin). 6.4 MIL-DTL-3933/14 replacements. The attenuators described herein are direct replacements for some of the MIL-DTL-3933/14 attenuators. TABLE II.
