|Significance and Use|
5.1Synthesized iso-paraffins (SIP) fuel are being approved for blending with jet fuel provided that they meet a purity specification of more than 97% farnesane, more than 98% saturated hydrocarbons, and less than 1.5% hexahydrofarnesol in accordance with Specification . This test method provides a method of determining the percentage of farnesane (purity) in the synthesized iso-paraffins (SIP) fuel for blending with jet fuel.
1.1This test method covers the determination of farnesane (2,6,10-trimethyldodecane), saturated hydrocarbons, and hexahydrofarnesol content in synthesized iso-paraffins (SIP) fuel for blending with jet fuel by gas chromatography.
1.2Farnesane is determined from 96% to 99.9% by mass. Sum of saturated hydrocarbons including farnesane is determined from 97% to 99.9% by mass, and hexahydrofarnesol is determined from 0.02% to 2.0% by mass.
1.3This test method does identify and quantify main impurities or group type of impurities but does not purport to identify all individual components that can be present in synthesized iso-paraffins (SIP) fuel for jet fuel blending.
1.4This test method is inappropriate for impurities that boil at temperatures higher than 460C or for impurities that cause poor or no response in a flame ionization detector.
1.5The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.6This 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.
1.7This 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.
