Standard Test Method for Fuel Injector Shear Stability Test (FISST) for Polymer Containing Fluids
SIGNIFICANCE AND USE
4.1 This test method evaluates the percent viscosity loss for polymer-containing fluids resulting from polymer degradation in the high shear nozzle device. Minimum interference from thermal or oxidative effects are anticipated.
4.2 This test method is not intended to predict viscosity loss in field service for different polymer classes or for different field equipment. Some correlation for a specific polymer type in specific field equipment can be possible.
SCOPE
1.1 This test method covers the measurement of the percent viscosity loss at 100 °C 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 1: Test Method D2603 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.
Note 2: This test method was originally published as Procedure B of Test Methods D3945. 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 D3945 often give different results.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.2.1 Exception—PSI is mentioned in parentheses for instruments that have only PSI gauges. Horsepower, HP, is listed in parentheses since the motor labels display this value.
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.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3. Summary of Test Method
3.1 The polymer-containing fluid is passed through a diesel injector nozzle at a shear rate that causes the less shear stable
polymer molecules to degrade. The resultant degradation reduces the kinematic viscosity of the fluid under test. The reduction in
kinematic viscosity, reported as percent loss of the initial kinematic viscosity, is a measure of the shear stability of the
polymer-containing fluid.

equipment. Some correlation for a specific polymer type in specific field equipment can be possible.
