描述燃气轮机发动机燃料系统部件达到选定清洁度水平的一般指南，并描述测量和报告燃料系统部件湿润部分污染水平的实验室方法。与SAE J1227（涵盖液压部件）中的规定一样，本规程包括验收等级指南，但不试图设置这些等级。

To describe general guidelines for achieving selected levels of cleanliness in gas turbine engine fuel system components and to describe laboratory methods for measuring and reporting the contamination level of the wetted portion of fuel system components. As in SAE J1227 (covering hydraulic components) this practice includes guidelines for levels of acceptance but does not attempt to set those levels.
