标准摘要
[中文适用范围]： ISO 24253 的这一部分规定了一种田间测量方法，以确定大田作物中喷雾的数量和分布，由水平喷杆喷雾机向下定向施用。 本国际标准可用于使用喷杆喷雾器喷洒的苗木和小型灌木作物（小醋栗）。 注：当对作物冠层宽度上的喷雾沉积感兴趣时，建议使用 ISO 22522。 ISO 24253 的这一部分允许灵活安排现场测试，但指定了标准化测量程序，有助于比较来自不同现场实验的结果或与实验室测试进行比较，例如 ISO 5682-2 中指定的测试。 本国际标准不适用于监管框架或用于监管框架。 [外文原描述]： 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.
