In the event of a conflict between the text of this document and the ref- erences cited herein, the text of this specification shall

29、 take precedence, except in the case where MIL- STO-1472 is concerned, In such a case, MIL-STD-1472 shall govern. Nothing in this document, however, supersedes applicable laws and regulations unless a specific exemption has been obtained. 3 3. REQUIREMENTS. 3. 1 Desian. 3.1.1 Selection of specificat

30、ion and standards. Specifications and standards, necessary commodi- ties, and services not specified herein shall be selected in accordance with MIL-STD-143. 3.1.2 mteriala. The selection of materials and processes shall be IAW MIL-STD-1568 and MIL- STD-1587. Materials not covered by this specificat

31、ion or referenced document shall be suitable for the in- tended environment and application. The contractor shall not use nonstandard or proprietary materials and processes without prior government approval. 3.1.2.1 Dissimilar metals. Unless protected against electrolytic corrosion, dissimilar metal

32、s shall not be used in intimate contact with each other. Dissimilar metals are defined in MIL-STD-889. 3.1.2.2 Primers. MIL-P-23377 and MIL-P-26915 epoxy primers shall be used on aluminum and ferrous alloys respectively. 3.1.2.3 Topco and aluminum alloy fasteners shall be anodized per MIL-A-8625. Fa

33、stener installation shall be IAW MIL- STB-1568. Fastener quality shall be IAW US Air Force Drawing 8838302. All screws, bolts, nuts, pins, and other fastening devices shall be properly designed, manufactured, and installed with adequate means Licensed by Information Handling ServicesMIL-T-B3BOB 17 U

34、 777770b 042b325 4 W MIL-T- 83808 (84) of preventing loss of torque or adjustment. Cotter pins, lock washers, or nylon patches shall not be used for this purpose, except for attachment of trim items or as provided in commercial (see 6.3.2) compo- nents. All bolt/washer/nut fasteners shall be a minim

35、um grade five hardness. Tapped aluminum threads shall have a minimum thread engagement of at least two times the nominal fastener diameter. 3.1.2.8 Sealants for permanent fasteners. All joints, rivets and mating/faying surfaces of exterior and interior components shall be sealed using MIL-S-81733. 3

36、.1.2.9 Conformal coating. Printed circuit./printed wire boards shall be conformal coated with materi- als IAW MIL-1-46058. 3.1.2.10 Welding. Ferrous and aluminum welding shall be IAW American Welding Standards and MIL- STD-1595, If there is a conflict between the two standards, the most stringent re

37、quirement shall take precedence. 3.1.2.1 1 Soldering. Soldering shall be IAW MIL-STD-454, requirement 5. 3.1.2.12 Brazing. Brazing shall be performed IAW MIL-B-7883. 3.1.2.13 Commercial off-the-shelf equipment. All commercial equipment and parts shall be assessed by the contractor as to their suitab

38、ility to function in the intended environment and comply with the systems life expectancy requirements. 3.1.2.14 Galvanized steel. Many producers of zinc-coated steel apply inhibitors to protect their prod- ucts from moisture during shipment and storage. Some of these inhibitors interfere with Pretr

39、eatments re- sulting in poor priming surfaces. Contractors shall consult with their supplier of galvanized steel for rec- ommendations on the pretreatment to be used on their respective product. 3.1.3 nesian and construction. The vehicle shall be constructed so that parts do not work loose in servic

40、e and shall withstand the loads, shocks, vibrations, and other conditions incident to operation, shipping, and storage with minimum loss of time for maintenance, repair, and servicing. The design of the vehicle shall ensure safe, efficient, and economical operation. All assemblies, controls, and ins

41、talled equipment shall be located so that there is no adverse interference with each other, or with the operation, and shall be readily accessible for maintenance, operation, and replacement. All rotating and reciprocat- ing parts and all parts subject to high operational temperatures or subject to

42、being electrically energized, that are of such nature or so located as to be hazardous to personnel, shall be guarded or insulated to the extent necessary to eliminate the hazard. All walking/stepping surfaces shall be of the nonskid type. Wear points shall be designed to permit replacement of wear

43、surface components. a. Finishes. Protective coating application shall be considered during the design stage. Sharp, angular corners are undesirable due to coating failures on outside corners (too thin) and the tendency of coatings to bridge inside corners. Smooth, round corners allow uniform coating

44、 thickness and avoids creation of possible sump areas. All mechanically joined compo- nents shall be finished before assembly. Welded structures shall have finishes applied after welding. When welded and bolted assemblies are used, manufacturing steps shall be ar- ranged to minimize disruption of th

45、e protective coatings. Supplementary corrosion prevention treatments - rustproofing, sealants, greases, etc., shall be applied after finish application. All metallic surfaces shall be treated for corrosion prevention. b. Jointsjfavina. Joint designs shall minimize crevices formed by overlapping surf

46、aces and shall point away from the forward direction of vehicle travel or point down. Butt welds are preferable to lap welds. Continuous welds are preferable to tack welds. The joints shall be designed so there are no gaps on joint laps. This can be accomplished by continuous welds, solder or sealan

47、t bead lines. All faying surfaces shall be primed and completely coated with sealant prior to assembly. 6 Licensed by Information Handling ServicesMIL-T- 83808 (84) c. Core panel structura. Pretreat and prime all internal surfaces prior to assembly. Pretreat and prime interior panel skin and faying

48、surfaces prior to assembly. Coat entire faying surface area with sealant during assembly and apply sealant bead after assembly to the lap joint. The panelsshall then be foamed in placed using non-reverting polyurethane. d. Drain holeg Structures shall be designed to avoid pockets where debris or moi

49、sture might accumulate. Inverted u-channel structural members do not accumulate moisture or debris. Closed structural configurations should have sloping surfaces towards drain holes which are adequately sized and placed in the lowest sump areas. All interior surfaces shall be treated IAW MIL-STD-808, with priming being the minimum finish requirement. The finish shall be reappliedlapplied through drain holes after welding operations. e. Doors. Consideration shall be given to open configuration doors. Use of single panel doors eliminate crevice corrosion sites and leads to easier
