3、 COMMERCIAL ITEM DESCRIPTION FILTER, FLUID, PRESSURE AND FILTER ELEMENT, FLUID, PRESSURE-AUTOMOTIVE FUEL (45 GPH FILTRATION) The General Services Administration has authorized the use of this commercial item description (CID) as a replacement for MS51088B and MS51090A, which are canceled. This CID a
4、lso replaces the portions of canceled MIL-F-45356B which apply to MS51088B and MS51090A. 1. SCOPE. This CID covers requirements for a filter assembly with a coarse filtration element and the replacement element for use in the fuel system of internal combustion engines and accessories. 2. SALIENT CHA
5、RACTERISTICS 2.1 Materials. Unless otherwise specified herein, the materials used shall be in accordance with the manufacturers material specifications for pressure fluid filters. The use of recovered materials made to conform with regulatory requirements is acceptable providing that all the require
6、ments of this CID are met (see 3). 2.1.1 Cover (head). The cover shall be made of a material which shall allow the filter assembly to perform to the requirements of this CID. If made of steel, cover material shall be zinc coated and the finished cover shall be treated with a corrosion resistant inhi
7、bitor as per ASTM D6386. 2.1.2 Bowl. The filter bowl material shall be made of either brass, annealed, Unified Numbering System (UNS) C21000, C22000, or C23000 per ASTM B36/B36M; or zinc coated steel strip, carbon, cold rolled, as per ASTM A109/A109M. Steel bowls shall be treated with a corrosion re
8、sistant inhibitor as per ASTM D6386. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-A-A-52470A 2 2.1.3 Filter element. The filter element shall be made of a material which shall allow the filter assembly to perform to the requirements of this CID. 2
9、.1.4 Filter bowl and filter element gaskets. The materials for the filter bowl and filter element gaskets (see figures 1 to 3), old MS 51091-1 to -3, are superseded by the new PINs A52468-1 to -3 and shall be in accordance with A-A-52468. 2.1.5 Filter head center bolt gasket. The filter head center
10、bolt gasket, PIN 52470-3 (see figures 1 and 3) shall be made of soft annealed copper, cold rolled, sheet or strip, Rockwell B-55 maximum per ASTM B152/B152M. 2.2 Design and construction. 2.2.1 Envelope. Unless otherwise specified in figures 1 and 2, the filter assembly and the replacement element sh
11、all be constructed in accordance with the manufacturers specifications/ drawings. The filter assembly shall be compatible with the center bolt and with the called-out gaskets. 2.2.2 Gaskets. The design and construction of the gaskets shall be to the form, fit, and dimensions as shown in figures 1 an
12、d 3. 2.2.3 Servicing. Servicing, including cleaning and reassembly shall be easily accomplished without disturbing the filter assemblys connection to the engine and shall be designed to prevent improper assembly. 2.3 Performance. 2.3.1 Pressure-temperature resistance. The filter assembly shall show
13、no signs of leakage or permanent deformation after being pressure tested at minus (-) 653 degrees Fahrenheit (F), 803 F, and 1603 F. The pressure used in this test shall be 40 pounds per square inch (psi). Test fluids shall be used for all tests. For all tests, the pressure shall be applied for 5 mi
14、nutes and reduced to zero. 2.3.2 Flow rate. The flow rate of the filter assembly or the replacement element shall be 45 gallons per hour (gph). The maximum differential pressure across the filter assembly or replacement element shall not exceed 8 psi at end completion the filtering efficiency test (
15、see 2.3.3). 2.3.3 Filtering efficiency. The filtering efficiency shall conform to the requirements specified in table I. Filters shall be tested with coarse contaminants in accordance with table II. Test fluids shall have a solid contaminant content of no more than 5 milligrams per liter (mg/l) and
16、temperature of 9010 F. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-A-A-52470A 3 TABLE I. Filtering efficiency.

18、 assembly shall show no evidence of cracking, deformation, loosening, or leakage in the body at the gasket or at the fittings after exposure to a sinusoidal motion for 3 hours along each axis. A frequency range of 5 to 500 cycles per second shall be used. The sweep time for the frequency range of 5
19、Hertz (Hz) to 500 Hz and return to 5 Hz shall be 15 minutes. 2.4 Identification and marking. Identification and marking of filter assemblies and replacement elements shall be permanent and legible and shall include, as a minimum, the part identification number (PIN) and the manufacturers CAGE code a
20、nd part number (see 6.2 and 6.3). 3. REGULATORY REQUIREMENTS. The offeror/contractor is encouraged to use recovered materials to the maximum extent practicable, in accordance with paragraph 23.403 of the Federal Acquisition Regulation (FAR). 4.
