Unless otherwise specified herein. the materials used shall be in accordance with the manufacturers material specifications for strainers. The use of recovered materials m
4、ade in conformance with regulatory requirements is acceptable providing that all requirements of this CID are met (see note e). 1. Cover (head). The cover shall be made 3f a material which shall allow the strainer to perform to the requirements =f this CID. If made of steel, cover material shall be
5、zinc coated and the finished cover shall be treated with a corrosion inhibitor as per ASTM D2092, method B. 2. Bowl. The bowl material shall be brass, annealed, per ASTM B36 Unified Numbering System C24000, C26000, or C26800; zinc coated steel strip, carbon, cold rolled, per ASTM A109; or glass, ann
6、ealed, transparent. Steel bowls shall be treated with a corrosion inhibitor as per ASTM D2092, methoc! B. Beneficial comments, recommendations, additions, deletions clarifications, etc. and any other data which may improve this document should be sent by letter to: U.S. Army Tank-Automotive Command,

Material: Steel, stainless, type 304 or 316; brass, high zinc content, copper-zinc alloy; or commercial bronze-copper, commercially pure. 4. Gasket. The filter bowl gasket material shall be in accordance with CID A
9、-A-52468-4. b. Desian and construction. 1. Envelope. The strainer shall be constructed to the form and dimensions as specified herein (see figure 1). The filter bowl shall be compatible with the bowl gasket. Design and construction that is not specified herein shall be in accordance with the best co
10、mmercial practices. 2. Bowl gasket. The filter bowl gasket shall be in accordance with CID A-A-52460-4. 3. Servicing. Servicing, including cleaning and reassembly, shall be easily accomplished without disturbing the strainers connection to the engine and shall be designed to prevent improper assembl
11、y. c. Performance. 1. Pressure-temperature resistance. The strainer shall show no signs of leakage or permanent deformation after being pressure tested at -65+ 3 degrees Fahrenheit (OF), 80 + 3OF, and 160 + 3F. The pressure used in thic test shall be 15 pounds per square inch (psi). -65OF and 80F te
12、sts. Air shall be used or the 160F test. For all tests the pressure shall be applied for 5 minutes and reduced to zero. - Test fluids shall be used for the 2. Flow rate. The nominal flow rate through the strainer shall be 10 gallons per hour (gph). The maximum differential pressure across the strain
13、er shall not exceed 4 psi. 3. Vibration resistance. The strainer shall show no evidence of cracking, deformation, loosening or leakage in the body at gaskets or at the fittings after exposure to a sinusoidal vibration for 3 hours along each axis. A frequency range of 5 to 500 cycles per second shall
14、 be used. The sweep time for the frequency range of 5 Hertz (Hz) to 500 Hz and return to 5 Hz shall be 15 minutes. * 4. Identification and markings. Identification and marking of strainers shall be permanent and legible and shall include as a minimum the manufacturers identification code (CAGE), and
15、 the part identification number (PIN) (see notes b and c) . QUALITY ASSURANCE PROVISIONS a. Responsibility for inspection. The contractor is responsible for the performance of all inspections (examinations and tests). b. Contractor certification. The contractor shall certify and maintain substantiat
16、ing evidence that the product offered meets the salient characteristics of this commercial item description and the the product conforms to the producers own drawings, specifications, workmanship standards, and quality assurance practices.
