Historical Standard: ASTM D5275-03 Standard Test Method for Fuel Injector Shear Stability Test (FISST) for Polymer Containing Fluids
SUPERSEDED (see Active link, below)
ASTM D5275
1. Scope
1.1 This test method measures the percent viscosity loss at 100C of polymer-containing fluids using fuel injector shear stability test (FISST) equipment. The viscosity loss reflects polymer degradation due to shear at the nozzle.
Note 1Test Method D 2603 has been used for similar evaluation of this property. It has many of the same limitations as indicated in the significance statement. No detailed attempt has been undertaken to correlate the results by the sonic and the diesel injector methods. Equipment and replacement parts are no longer available for Test Method D 2603 as it is currently written. The test method is currently under revision.
Note 2This test method was originally published as Procedure B of Test Methods D 3945. The FISST method was made a separate test method after tests of a series of polymer-containing fluids showed that Procedures A and B of Test Methods D 3945 often give different results.
1.2 The values given in SI units are to be regarded as the standard. The inch-pound units given in parentheses are for information only.
1.3 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. Specific precautionary statements are given in Section 7.
