To be eligible for listing as an approved source of supply, a manufac

20、turer 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. 3.8 Certificate of compliance. A certificate of compliance shall be required from manufacturers requesting to

21、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 extent possible provided that the material meets or exceeds the operational and maintenance requirements, and

22、promotes economically advantageous life cycle costs. 3.10 Workmanship. The attenuator shall 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 in

23、spection. 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

24、 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 Defe

25、nse 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.

NOTES (This section contains information of a general or explanatory nature which may be helpful, but is not mandatory.) 6.1 Intended use. Attenuators conf

27、orming 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 prevent the proliferation of unnecessary duplicate specification

28、s, 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 contract or purchase order should specify the following: a.

29、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 for notification of change of product to the acquiring activ

30、ity, 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 anytime from a day to years after manufacture and can develop

31、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 t

32、his matter, refer to ASTM-B545 (Standard Specification for Electrodeposited Coatings of Tin). 6.4 MIL-DTL-3933/18 replacements. The attenuators described herein are direct replacements for some of the MIL-DTL-3933/18 non-screened attenuators. TABLE II. Replacement data. MIL-DTL-3933/18 PIN DLA Land

33、and Maritime drawing PIN 13015- M3933/18-05N 05 1/ M3933 non-screened (N) PINs may also be known without the ending N character. 6.5 Replaceability. Attenuators covered by this drawing will replace the same commercial device covered by contractor prepared specification or drawing. 6.6 Users of recor
