8、ich shall allow the filter assembly to perform to the requirements of this CID. 4. Bowl gasket. The filter bowl gasket shall be made of rubber conforming to ASTM D2000, classification number M2BG610A14B14EF21F17 or M2BG710A14B14EF21F17. b. Design and construction. 1. Filter assembly. Unless otherwis

9、e specified in figure 1, the filter assembly and the replacing element shall be constructed in accordance with the manufacturers specifications/drawings. The filter bowl shall be compatible with the bowl gasket. 2. Bowl gasket. The filter bowl gasket shall be in accordance with CID A-A-52468, part n

10、umber A52468-5. 3. 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. c. Performance characteristics. 1. Pressure-temperature resistance. The filter

11、assembly shall show no signs of leakage or permanent deformation after being pressure tested at -65 - + 3 degrees Fahrenheit (OF), 80 + 3OF, and 160 + 3OF. The pressure used in this test shall be 15 + 1 pounds per square-inch (psi). used for the -65OF and-80F tests. Air shall be used for the 160F te

12、st. For all tests the pressure shall be applied for 5 minutes and reduced to zero. Test fluids shall be 2. Flow rate. The flow rate of the fuel filter assembly shall be 21 gallons per hour (gph). The maximum differential pressure across the filter assembly shall not exceed 6 psi. Test fluid shall be

13、 a “Mineral Spirits“ or “Petroleum Spirits“ solvent (Stoddard solvent) and shall have a solid contaminant content of no more than 5 milligrams per liter (mg/i) and temperature of 90 - + 10F. 3. Filtering efficiency. The filtering efficiency shall conform to the requirements specified in table I. Fil

14、ters shall be tested with coarse contaminants in accordance with table II. The A.C. Spark Plug Division, Coarse Air Cleaner Dust, package no. 1543637 or equivalent, often referred to as “Arizona road dust“ or “AC coarse dust“ has been satisfactory for filter testing. 4. Vibration resistance. The fue

15、l filter 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 seconds shall be used. The sweep time for the frequency

16、range of 5 Hertz (Hz) to 500 Hz and return to 5 Hz shall be 15 minutes. d. Identification and marking. Identification and marking shall be permanent and legible and shall include, as a minimum, the manufacturers CAGE code and the part identification number (PIN), A52460-1 (see figure 1 and note b) *
