1.1 本指南适用于准备田间喷雾器校准程序的人员。目的是鼓励使用田间喷雾器提高农药施用的均匀性、准确性和安全性的方法。 1.2 以国际单位制表示的数值应视为标准值。括号中给出的值是英寸-磅单位的数学转换，仅供参考，不被视为标准值。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 有关具体的危险说明，请参阅第节 4. . ====意义和用途====== 2.1 本指南提供了用于广播、波段或row应用的吊杆式田间喷雾器的校准信息。它很容易适用于广播应用的无吊杆和空气载体式喷雾器，以及旋转雾化器，如旋转圆盘。由于农药应用中涉及的变量的性质，适用于所有情况的单一校准程序是不可行的。电子控制器和其他辅助设备应通过其中一种方法进行校准。

1.1 This guide is for those who prepare field sprayer calibration procedures. The purpose is to encourage methods that will improve uniformity, accuracy, and safety of pesticide application with field sprayers. 1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements see Section 4 . ====== Significance And Use ====== 2.1 This guide provides information on the calibration of boom-type field sprayers used for broadcast, band, or row applications. It is easily adapted to boomless and air-carrier type sprayers for broadcast applications and to rotary atomizers such as spinning disks. A single calibration procedure that is applicable in all situations is not feasible because of the nature of the variables involved in pesticide application. Electronic controllers and other aids should be calibrated by one of these methods.
