1.1 本试验方法包括通过气相色谱法测定用于与喷气燃料混合的合成异烷烃（SIP）燃料中的法尼烷（2,6,10-三甲基十二烷）、饱和烃和六氢法尼醇含量。 1.2 法尼烷由96确定 % 至99.9 % 按质量计算。饱和烃（包括法尼烷）的总和由97确定 % 至99.9 % 以质量计，六氢法尼醇由0.02确定 % 至2.0 % 按质量计算。 1.3 本试验方法确实识别和量化了主要杂质或杂质组类型，但无意识别合成iso中可能存在的所有单个成分- 用于喷气燃料混合的石蜡（SIP）燃料。 1.4 本试验方法不适用于在高于460℃的温度下沸腾的杂质 °C或导致火焰离子化检测器响应差或无响应的杂质。 1.5 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.6 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.7 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 合成的异烷烃（SIP）燃料被批准与喷气燃料混合，前提是它们满足97%以上的纯度规格 % 法尼赛，98岁以上 % 饱和烃，小于1。 5. % 六氢法尼醇符合规范 D7566 . 本试验方法提供了一种测定用于与喷气燃料混合的合成异烷烃（SIP）燃料中法尼烷（纯度）百分比的方法。

1.1 This 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. 1.2 Farnesane 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. 1.3 This 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. 1.4 This test method is inappropriate for impurities that boil at temperatures higher than 460 °C or for impurities that cause poor or no response in a flame ionization detector. 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. ====== Significance And Use ====== 5.1 Synthesized 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 D7566 . 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.
