scope:

This International Standard specifies the system of colour coding for identification of all types of hydraulic spray nozzles, such as flat and cone nozzles used for the application of crop protection products in agriculture.

This International Standard is not applicable to nozzles where there is more than one component influencing flow rate. It might not be applicable to liquid fertilizer applications.

It allows for flow recognition on small parts in order to avoid any confusion under normal conditions of use.
