scope:

This International Standard specifies the test method for the determination of the volume and the concentration of the drainable volume of sprayers, in connection to the emptying of the diluted residue of the spray tank by using its outlet and other outlets allowing draining (e.g. suction filter, filling connection) at the end of the cleaning procedure.

It applies to agricultural sprayers used for crop protection and liquid fertilizer applications for both brand new sprayers and sprayers already in use.
