ISO 22866:2005建立了用于测量所有类型设备的液滴漂移的原则，这些设备设计用于应用植物保护产品。详细规范涉及拖拉机安装、牵引和自行式农业喷雾器，用于可耕地作物（吊杆喷雾器）和灌木和树木（包括葡萄藤、啤酒花、水果）作物（包括广播空气辅助喷雾器）。 其定义的原则也适用于任何手持设备或飞机，但此类系统的详细协议未包含在定义的规范中。 它规定了进行现场测量，以确定在距离处理区域一定距离处进行喷涂时的喷雾漂移量，以进行风险评估。定义了标准测量距离，用于比较不同实验的结果。

ISO 22866:2005 establishes principles for the measurement of droplet drift from all types of equipment designed for applying plant protection products. Detailed specifications relate to tractor-mounted, trailed and self-propelled agricultural sprayers operating in arable field crops (boom sprayers) and in bush and tree (including vines, hops, fruit) crops (including broadcast air-assisted sprayers). The principles it defines are also applicable for any hand-held equipment or aircraft, but detailed protocols for such systems are not included in the specifications defined. It specifies the making of field measurements so as to determine the quantities of spray drift during application at defined distances from a treated area for risk assessment purposes. Standard measurement distances are defined that are used to enable the results from different experiments to be compared.
