Standard Test Method for
Determining Water Separation Characteristics of Aviation Turbine Fuels by Portable Separometer
NOTE- This method requires the use of the Alumicel Coalescer cell in order to meet the reproducibility and repeatability referenced in the Standard.
This standard has been approved for use by agencies of the Department of Defense.
EMCEE MODEL 1140 Microseparometer- self contained, portable, suitable for laboratory and field use.
1.1 This test method covers a rapid portable means for field and laboratory use to rate the ability of aviation turbine fuels to release entrained or emulsified water when passed through fiberglass coalescing material.
1.2 The procedure section of this test method contains two different modes of test equipment operation. The primary difference between the modes of operation is the rate of fuel flow through the fiberglass coalescing material. Test method selection is dependent on the particular fuel to be tested.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
