标准范围

本国际标准描述了估算航空涡轮机净比能的程序使用氢含量数据的燃料。它不适用于纯碳氢化合物。该方法纯粹是经验方法，仅适用于通过常规精炼获得的液态烃燃料符合航空涡轮机和发动机规范要求的常规原油加工工艺沸点范围和成分有限的喷气发动机燃料。注1:该方法旨在作为净比能的实验测定不适用的情况下的指南不可用且无法方便地进行，且对于规范和类似要求，评估结果令人满意目的。不打算使用净比能的估计值代替实验测定的值价值观注2:根据碳氢燃料的硫含量、氢含量和密度估算碳氢燃料的净比能为只有当燃料属于明确定义的类别，且净比能和硫之间存在关系时，才有理由通过对代表性样品的精确实验测量，得出了含量、氢含量和密度这个班的学生。即使是在这一类中，也必须考虑到个别燃料的估算可能会出现大量错误的可能性辨识。注3:本国际标准中用于建立相关性的燃料定义见附录A。

This International Standard describes a procedure for the estimation of the net specific energy of aviation turbinefuels using hydrogen content data. It is not applicable to pure hydrocarbons.The method is purely empirical and is applicable only to liquid hydrocarbon fuels derived by normal refiningprocesses from conventional crude oil which conform to the requirements of specifications for aircraft turbine andjet engine fuels of limited boiling ranges and compositions.NOTE 1 The method is intended for use as a guide in cases where an experimental determination of net specific energy isnot available and cannot be made conveniently, and where an estimate is considered satisfactory for specifications and similarpurposes. It is not intended that estimated values of the net specific energy be used in place of experimentally determinedvalues.NOTE 2 The estimation of the net specific energy of hydrocarbon fuel from its sulfur content, hydrogen content and density isjustifiable only when the fuel belongs to a well-defined class for which a relationship between net specific energy and sulfurcontent, hydrogen content and density has been derived from accurate experimental measurements on representative samplesof this class. Even in this class, the possibility that the estimates can be in error by large amounts for individual fuels must berecognized.NOTE 3 The fuels used to establish the correlation presented in this International Standard are defined in annex A.
