ASTM E550-87(2002)

This guide covers the calibration of row, band, and broadcast applicators. Attainment of accurate and more uniform application can reduce the quantity of active ingredient required for a given degree of control, thus improving environmental quality and safety at a more economical cost. A single-calibration procedure applicable in all situations is not feasible because of the nature of the variables involved in chemical applications.

1.1 This guide is for those who prepare granular pesticide ground applicator calibration procedures. The purpose is to encourage methods that will improve uniformity and accuracy of application with granular applicators.

1.2 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 .

1.3 The values stated in acceptable metric units are to be regarded as the standard. The values in parentheses are for information only.
