3、OMMERCIAL ITEM DESCRIPTION FILTER, FLUID, PRESSURE, AUTOMOTIVE FUEL (10 GPH FILTRATION) The General Services Administration has authorized the use of this commercial item description (CID) as a replacement for MS51085C, which is cancelled. This CID also replaces the portions of cancelled MIL-F-45356

4、B, which apply to MS51085C. 1. SCOPE. This CID covers requirements for a filter assembly with a fine filtration element for use in the fuel systems of internal combustion gasoline engines and personnel heaters. 2. CLASSIFICATION. Filter assemblies shall be furnished in the following types (see 7.2).

5、 Type I - Filter assembly with 15 pounds per square inch (psi) pressure requirements, without lockwire. Type II - Filter assembly with 300 psi air pressure requirements, with lockwire. 3. SALIENT CHARACTERISTICS 3.1 Materials. Unless otherwise specified herein, the materials used shall be in accorda

6、nce with the manufacturers materials specifications for pressure fluid filter as required to meet the performance requirements of this CID. The use of recovered materials made to conform to regulatory requirements is acceptable provided all requirements of this CID are met (see 4). 3.1.1 Cover (head

7、). Type II filter covers shall be made of metal. If made of steel, cover material shall be zinc coated, and the finished cover shall be treated with a corrosion resistant inhibitor as per ASTM D6386. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-A-

8、A-52472A 2 3.1.2 Bowl. Type II filter bowl material shall be brass, annealed, Unified Numbering System (UNS) C24000, C26000, C26800 per ASTM B36/B36M, or zinc coated steel strip, carbon, cold rolled per ASTM A109/A109M. Steel bowls shall be treated with a corrosion resistant inhibitor per ASTM D6386

9、. 3.2 Design and construction. Unless otherwise specified in figure 1, the design and construction of the filter assembly shall be in accordance with the manufacturers specifications/drawings. The cover and bowl for the type II filter shall have a provision for and secured together with lockwire. 3.

10、2.1 Filter element. The filter element shall be of the fine filtration type. 3.2.2 Servicing. Servicing, including cleaning and reassembly, shall be easily accomplished without disturbing the filter assembly connection to the engine and shall be designed to prevent improper assembly. 3.3 Performance

11、. 3.3.1 Pressure-temperature resistance. The filter assembly shall be pressure tested at -653 degrees Fahrenheit (F), 803 F, and 1603 F. Test fluid used for the -65 F and 80 F tests shall be a mineral/petroleum spirit solvent having 100 F minimum flash point (see 3.3.3). Air shall be used for the 16

12、0 F test. For all tests, the pressure shall be applied for 5 minutes and reduced to zero. At a pressure of 15 psi, the type I filter assembly shall show no signs of leakage or permanent deformation during and after the pressure test. The type II filter assembly shall show no signs of leakage while s

13、ubmerged in water under an air pressure of 300 psi and, afterwards, shall show no signs of permanent deformation. 3.3.2 Flow rate. The flow rate of the filter assembly shall be 10 gallons per hour (gph). The maximum pressure differential across the filter assembly shall not exceed 4 inches of water.
