作物保护设备. 使用试验台测量水平喷管式喷雾器潜在喷雾飘移的方法

[中文适用范围]： 本国际标准提供一种测试方法，用于测量水平 boom 喷雾器的喷雾沉积，使用一个测试台。喷雾沉积可以给出潜在喷雾漂移值。这些测量可用于比较同一喷雾器上的不同喷雾设置。本国际标准适用于安装在拖拉机、牵引式和自走式水平 boom 喷雾器，用于旱田作物；以及水平 boom 喷雾器用于果树/葡萄园杂草控制和园林作物的喷雾应用。如果打算用于喷雾漂移分类，则比较限于喷嘴类型、喷雾压力和 boom 高度。 [外文原描述]： ISO 22401:2015 provides a test method to measure spray sedimentation from horizontal boom sprayers using a test bench. The sedimentation measure gives a value for potential spray drift. These measurements can be used to compare different sprayer setups on the same sprayer. ISO 22401:2015 is applicable to mounted, trailed and self-propelled horizontal boom sprayers used in arable crops; and horizontal boom sprayers used for weed control in orchards/vineyards and spray application on horticultural crops. ISO 22401:2015 is intended for booms using a uniform set of spray generators. If intended for spray drift classification of the sprayer, the comparison is limited to nozzle type, spray pressure and boom height. NOTE Further investigations and tests are on-going to consider other parameters for classification aims (e.g. air assisted system, forward speed, nozzle spacing and orientation).
