ISO 22369-2:2010规定了田间作物喷雾器的漂移分类程序，该程序通过符合ISO 22866的喷雾漂移沉降的现场测量，包括所需的试验方法和评估标准。它还允许分配ISO 22369-1规定的喷雾减小漂移等级。 ISO 22369-2:2010旨在通过与参考喷洒系统进行比较，确定田间作物喷洒机的减漂性能，以便对田间作物喷洒机进行评级（分类）。 适用于大田作物中使用的安装式、牵引式和自行式大田作物喷雾机。

ISO 22369-2:2010 specifies the drift classification procedure for field crop sprayers by field measurements of spray drift sedimentation in conformity with ISO 22866, including the test methods and evaluation criteria needed. It also allows the allocation of the spray drift reduction classes specified by ISO 22369-1. ISO 22369-2:2010 is intended to determine the drift reducing performance of field crop sprayers by comparison with a reference spraying system, in order to rate (classify) the field crop sprayers. It is applicable to mounted, trailed and self-propelled field crop sprayers used in field crops.
