本文件规定了喷雾器喷嘴流量识别的颜色编码系统。 适用于农作物保护产品应用中使用的平喷嘴和锥形喷嘴等水力能喷嘴。 本文件不适用于可调喷嘴。 它允许对小零件进行流量识别，以避免在正常使用条件下出现任何混淆。

This document specifies the system of colour coding for flow rate identification of nozzles used on sprayers. It is applicable to hydraulic energy nozzles such as flat and cone nozzles used for the application of crop protection products. This document is not applicable to adjustable nozzles. It allows for flow recognition on small parts in order to avoid any confusion under normal conditions of use.
