Materials not specified shall be selected by the contractor an

25、d shall be subject to all provisions of this specification. 3.4 Material deterioration prevention and control. The air compressor shall be fabricated from compatible materials, inherently corrosion resistant or treated to provide protection against the various forms of corrosion and deterioration th

26、at may be encountered in any of the applicable operating and storage environments to which the air compressor may be exposed. 3.4.1 Dissimilar metals. Dissimilar metals shall not be used in intimate contact with each other unless protected against galvanic corrosion. Dissimilar metals and methods of

For the purpose of this requirement, recovered materials are those materials which have been collected from solid waste and reprocessed to become a source of r

29、aw materials, as distinguished from virgin raw materials. The components, pieces and parts incorporated in the air compressor may be newly fabricated from recovered materials to the maximum extent practicable, provided the air compressor produced meets all other requirements of this specification. U

30、sed, rebuilt or remanufactured components, pieces and parts shall not be incorporated in the air compressor. 3.5 Operatin5 temperature. the compressors shall perform as specified herein in any ambient temperature from 120 to -25 OF. 4 Provided by IHSNot for ResaleNo reproduction or networking permit

All rotating or reciprocating parts and other parts subject to high operational temperatures that are of such a nature or are so located as to bi a hazard to operating personnel, shall be guarded or insulated

32、 to the extent necessary to eliminate the hazard. Protective devices shall not impair the operating functions. 3.7 Maintainebility. The compressor shall operate as specified herein without repair or maintenance other than the contractors recommended normal scheduled adjustments and servicing, as est

33、ablished by a maintenance schedule prepared and submitted by the contractor prior to test. All major assemblies and installed attachments shall be accessible for maintenance repair and replacement without removal of other major assemblies and installed attachments not normally removed. Cover plates

34、which must be removed for component adjustment shall be equipped wit1 quick-disconnect fastenings. All fasteners shall be of corrosion-resistant material or shall be treated to be corrosion resistant. All screw threads shall be in accordance with FED-STD-H28.
