标准摘要
[中文适用范围]： 本文件制定了飞机液压系统中使用的部件（管道、软管和配件除外）的标记方案，以便在车间的任何组装或测试操作中都能清楚地看出正确的流体类型。 当组件安装在飞机上时，该标记没有任何作用。 [外文原描述]： This document establishes a scheme for the marking of components (other than pipelines, hoses and fittings) used in aircraft hydraulic systems, so that the correct type of fluid is readily apparent during any assembly or testing operations in workshops. The marking is not intended to serve any purpose when a component is installed in an aircraft.
英文名称Aircraft — Hydraulic components — Marking to indicate the fluid for which a component is approved
