1.1 本规范涵盖采购机构在制定合同项下航空涡轮燃料采购规范时的使用。 1.2 本规范定义了飞机认证中民用航空涡轮燃料的一种特定类型。本规范可作为描述从炼油厂到飞机的这种航空燃料质量的标准。 1.3 本规范不包括航空涡轮发动机中常用的燃料。这些在规范中列出 D1655 . 1.4 本规范规定的航空涡轮燃料可用于专门设计和认证的涡轮发动机以外的其他发动机。 1.5 允许使用EI/IP（能源研究所/石油研究所）测试方法。本规范的用户参考规范 D1655 （最新版本），航空涡轮燃料规范，第2段，参考文件和表1，航空涡轮燃料的详细要求，第4列，试验方法，以确定IP试验方法与特定详细要求的配对，以及第11节，试验方法，以确定联合标准和仲裁方法。 1.6 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。 1.6.1 例外情况- 压力单位也以磅/平方英寸为单位。 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。

1.1 This specification covers the use of purchasing agencies in formulating specifications for purchases of aviation turbine fuel under contract. 1.2 This specification defines one specific type of aviation turbine fuel for civil use in the certification of aircraft. The specification can be used as a standard in describing the quality of this aviation fuel from the refinery to the aircraft. 1.3 This specification does not include the fuels that are commonly used in aviation turbine engines. Those are listed in Specification D1655 . 1.4 The aviation turbine fuel defined by this specification may be used in other than turbine engines that are specifically designed and certified for this fuel. 1.5 The use of EI/IP (Energy Institute/Institute of Petroleum) test methods is permitted. The user of this specification is referred to Specification D1655 (latest revision), Specification for Aviation Turbine Fuels, Paragraph 2, Referenced Documents and Table 1, Detailed Requirements of Aviation Turbine Fuels, Column 4, Test Methods, to determine the pairing of the IP test method with the particular detailed requirement, and to Section 11, Test Methods, to identify jointed standards and referee methods. 1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.6.1 Exception— Units of pressure are also given in psi. 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.
