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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements see Section 4.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.


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.
