标准范围

本文件规定了评定燃气轮机燃料在燃料系统内沉积分解产物的倾向的程序。它适用于中间馏分油和宽馏分燃料，并特别规定了航空燃气轮机燃料的性能。测试结果指示燃气轮机运行期间的燃料热氧化稳定性，并且可以用于评估当液体燃料在指定温度下接触加热表面时形成的沉积物的水平。该方法也适用于由例如ASTM D7566[1]和Def Stan 91-091[2]的范围中定义的常规和合成混合组分组成的航空涡轮燃料。注:为了那些使用旧仪器的人的利益，非国际单位制单位和重新计算的数字在更合适的括号之间给出。

This document specifies a procedure for rating the tendencies of gas turbine fuels to deposit decomposition products within the fuel system. It is applicable to middle distillate and wide-cut fuels and is particularly specified for the performance of aviation gas turbine fuels.The test results are indicative of fuel thermal oxidation stability during gas turbine operation and can be used to assess the level of deposits that form when liquid fuel contacts a heated surface at a specified temperature.This method is also applicable to aviation turbine fuel that consists of conventional and synthetic blending components as defined in the scope of for instance ASTM D7566^[1] and Def Stan 91-091^[2].NOTE       For the benefit of those using older instruments, non-SI-units and recalculated numbers are given in between brackets where they are more suitable.
