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.
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 This standard does not purport to address all of the safety problems, 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.
1.3 The values stated in acceptable metric units are to be regarded as the standard. The values in parentheses are for information only.
