(Test Method)Standard Test Method for Determination of Static Dissipater Additives (SDA) in Aviation Turbine Fuel and Middle Distillate Fuels—High Performance Liquid Chromatograph (HPLC) Method
Standard Test Method for Determination of Static Dissipater Additives (SDA) in Aviation Turbine Fuel and Middle Distillate Fuels—High Performance Liquid Chromatograph (HPLC) Method
SIGNIFICANCE AND USE
5.1 This test method will allow the determination of static dissipater additive in jet and middle distillate. These additives reduce the hazardous effects of static electricity generated by transfer and movement of jet and middle distillate fuels.
SCOPE
1.1 This test method covers the determination of static dissipater additive (SDA) content of aviation turbine fuel and middle distillate fuels.
1.2 The precision of this test method has been established for aviation turbine fuel over the concentration range of 1 mg/L to 12 mg/L. Higher concentrations can be determined by dilution, but the precision of the test method will not apply.
Note 1: The SDA used to develop this test method was STADIS 4502 for aviation fuels and STADIS 450 and 4252 for middle distillates.
1.3 The test method includes a procedure to concentrate the sulfonic acid component in the SDA prior to analysis.
1.4 The test method only applies to SDAs that contain alkyl substituted sulfonic acid.
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.6 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.7 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.
