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 本规范规定了Jet A和Jet A-1航空涡轮燃料的最低性能要求，并列出了可用于民用发动机和飞机的可接受添加剂。规格 D1655 针对民用应用，并按此进行维护，但可用于军事、政府或其他专门用途。 1.3 本规范可作为描述从生产到飞机的航空涡轮燃料质量的标准。 然而，本规范并未规定确保分配系统中的燃料在批量认证后继续符合本规范所需的质量保证测试和程序。此类程序在其他地方有定义，例如国际民航组织 9977，EI/JIG标准 1530，夹具 1，夹具 2，API 1543，API 1595和ATA-103。 1.4 本规范不包括所有符合航空涡轮发动机要求的燃料。某些设备或使用条件可能允许比本规范所示更宽或更窄的特性范围。 1.5 本规范定义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。 1.6 本规范不再包括宽切航空涡轮燃料（Jet B）。FAA已经发布了一份特别的适航信息公告，该公告现在批准使用该规范 D6615 替换规范 D1655 作为Jet B的规范，请用户参考本标准。 1.7 以国际单位制表示的数值应视为标准值。然而，本标准中包含了其他测量单位。

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 the minimum property requirements for Jet A and Jet A-1 aviation turbine fuel and lists acceptable additives for use in civil operated engines and aircrafts. Specification D1655 is directed at civil applications, and maintained as such, but may be adopted for military, government or other specialized uses. 1.3 This specification can be used as a standard in describing the quality of aviation turbine fuel from production to the aircraft. However, this specification does not define the quality assurance testing and procedures necessary to ensure that fuel in the distribution system continues to comply with this specification after batch certification. Such procedures are defined elsewhere, for example in ICAO 9977, EI/JIG Standard 1530, JIG 1, JIG 2, API 1543, API 1595, and ATA-103. 1.4 This specification does not include all fuels satisfactory for aviation turbine engines. Certain equipment or conditions of use may permit a wider, or require a narrower, range of characteristics than is shown by this specification. 1.5 Aviation turbine fuels defined by this specification may be used in other than turbine engines that are specifically designed and certified for this fuel. 1.6 This specification no longer includes wide-cut aviation turbine fuel (Jet B). FAA has issued a Special Airworthiness Information Bulletin which now approves the use of Specification D6615 to replace Specification D1655 as the specification for Jet B and refers users to this standard for reference. 1.7 The values stated in SI units are to be regarded as standard. However, other units of measurement are included in this standard.
