Nothing in this specification, however, shall supersede applicable laws and regulations unless a specific exemption has been obtained. 3. REQUIREMENTS 3.1 Description. The compressor unit shall be portable, and shall consist of a recip
30、rocating compressor, driven by a diesel engine, and shal.1 produce not less than 20 cubic feet per minute (cfm) of free air at 5000 pounds per square inch gage (psig). The engine and compressor unit shall be shock mounted. The compressor unit shall be complete and self-contained, including a final a
31、ir filter and all other accessories. The compressor unit shall weigh not more than 1500 pounds dry and the dimensions shall not exceed 50 inches in height, 60 inches in length, and 48 inches in width. A water resistant tarpaulin shall be provided. Divingldiving support equipment shall meet all stand

The compressor shall be fabricated from compatible materials, inherently corrosion resistant or treated 5 Provided by IH
35、SNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-to provide protection against the various forms of corrosion and deterioration that may be encountered in any of the applicable operating and storage environ- ments to which the compressor may be exposed. 3.3.2 Dissi
36、milar metals. Dissimilar metals shall not be used in intimate contact with each other unless protected against galvanic corrosion. Dissimilar metals and methods of protection are defined and detailed in MIL-STD-889. 3.3.3 Identification of materials and finishes. The contractor shall identify the sp
37、ecific material, material finish or treatment for use with component and subcomponent, and shall make information available upon request to the contracting officer or designated representative. 3.3.4 Recovered materials. For the purpose of this requirement, recovered materials are those materials wh
38、ich have been collected from solid waste and reprocessed to become a source of raw materials, as distinguished from virgin raw materials. The components, pieces and parts incorporated in the compressor may be newly fabricated from recovered materials to the maximum extent practicable, provided the c
39、ompressor produced meets all other requirements of this specification. Used, rebuilt or remanufactured components, pieces and parts shall not be incorporated in the compressor. 3.4 Environmental conditions. 3.4.1 Operation.
