ISO 24253-2:2015规定了一种田间测量方法，以确定水平臂喷雾器向下喷洒的田间作物中的喷雾量和分布。当使用吊杆喷雾器喷洒时，它可用于苗圃树和小型灌木作物（小醋栗）。 注:如果对作物冠层宽度上的喷雾沉积感兴趣，建议使用ISO 22522。 ISO 24253-2:2015允许灵活安排现场试验，但规定了标准化测量程序，这些程序有助于比较不同现场试验的结果或与实验室试验进行比较，如ISO 5682-2中规定的结果。 ISO 24253不适用于监管框架。

ISO 24253-2:2015 specifies a method for field measurements to determine the quantity and distribution of spray in a field crop, treated by horizontal boom sprayers with downward directed application. It can be used for nursery trees and small size bush crops (young currants) when sprayed with boom sprayers. NOTE When interested in the spray deposition over width of the crop canopy, it is advised to use ISO 22522. ISO 24253-2:2015 allows flexibility in the arrangement of field tests, but specifies standardized measurement procedures that are useful to be able to compare the results from different field experiments or to compare with laboratory tests, such as that specified in ISO 5682-2. ISO 24253 is not intended for use in or for a regulatory framework.
