22、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.

Recycled, recovered, or environmentally prefer
24、able 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 shall be uniform in quality and free from any defects that
25、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 product for delivery shall consist of the group A inspecti
26、on 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 specified in the contract or order (see 6.2). When packaging
27、 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 Points packaging activities within the Military Service or D
28、efense 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
29、 of 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 ap
30、plication. 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 w
31、ill 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
32、shipment 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 growt
33、h 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. A
34、lloys 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). 6.4 MIL-DTL-3933/25 replacements. The attenuators described herein are direct replacements
35、for some of the MIL-DTL-3933/25 screened and non-screened attenuators (see table II).
