27、d and maintained by the contractor. The establishment and maintenance of a calibration system to control the accuracy of the measuring and test equipment shall be in accordance with ISO-10012-1 and NCSL-Z540-1. 4.2 Classification of inspections. The inspections specified herein are classified as fol
28、lows: a. Materials and finish inspection. b. Conformance inspection. 4.3 Materials and finishes inspection. Materials and finishes inspection shall consist of certification supported by verifying data that the materials and finishes listed in table I, used in fabricating and finishing the components
29、, are in accordance with the applicable drawing or requirements prior to such fabrication. TABLE I. Materials and finishes inspection. Material or finish Requirement paragraph Applicable specification Brass sheet - ASTM B36/B36M Tin plating - ASTM-B339 and ASTM B545 4.4 Inspection conditions. Unless
30、 otherwise specified herein, all inspections shall be performed in accordance with the test conditions specified in the “General Requirements“ of MIL-STD-202. 4.5 Conformance inspection. 4.5.1 Inspection of product for delivery.

Gaskets shall be examined to verify
33、that the design, construction, physical dimensions, and workmanship are in accordance with the applicable requirements (see 3.1, 3.2, 3.5, and 3.6.) 4.6.2 Mounting surface flatness (see 3.4). Mounting surface flatness shall be measured in accordance with ASME B46.1. 4.6.3 Surface roughness (see 3.5)
34、. Mounting surface roughness shall be measured in accordance with ASME B46.1. 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 materiel is to be performed by DoD or in-house contractor personn
35、el, 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 Defense Agency, or within the military services system commands. Packa
36、ging 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 a general or explanatory nature which may be helpful, but is not
37、mandatory.) 6.1 Intended use. Devices 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 the OEM application. 6.2 Ordering data. The contract or purchase order should s
38、pecify the following: a. Complete PIN (see 1.2). b. Requirements for delivery, and one copy of the conformance inspection data or the certificate of compliance that parts have passed conformance inspection with each shipment of parts by the manufacturer. c. Whether the manufacturer performs the grou
39、p A inspection or provides a certificate of compliance with group A requirements. d. Requirements for notification of change in product to acquiring activity, if applicable. e. Requirements for packaging and packing. 6.3 Replaceability. Devices covered by this drawing will replace the same commercia
40、l device covered by a contractor prepared specification or drawing. 6.4 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 dev
41、elop 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
42、 on this matter, refer to ASTM-B545 (Standard Specification for Electrodeposited Coatings of Tin).
