Procedure for Measuring Distribution Uniformity and Calibrating of Small Granular Broadcast Applicators
Published by the American Society of Agricultural and Biological Engineers, St. Joseph, Michigan www.asabe.org ASAE ASAE S341.6 March 2024Keywords: ,Applicators, Distribution, Granular, Spreaders, Test 1 Purpose and Scope 1.1 Purpose. The purpose of this Standard is to establish a uniform method of determining and reporting performance data on broadcast spreaders designed to surface apply granular materials for 18.3 m (60‘) spread width or less. Tests performed according to this Standard make it possible to predict distribution uniformity of a broadcast spreader and to compare spreader distribution patterns. 1.2 Scope. This Standard pertains to centrifugal, pendulum, and other types of broadcast spreaders designed for dry granular application while operating on the soil surface. Portions of the test procedures outlined herein are suitable for determining the delivery rate of gravity or drop spreaders; however, additional tests not covered in this Standard are needed to completely evaluate the performance of gravity spreaders. This Standard does not cover dry pneumatic granular applicators or large broadcast spreaders that are used to surface apply granular materials for 18.3 m (60‘) spread width or more.
