Published by the American Society of Agricultural and Biological Engineers, St. Joseph, Michigan www.asabe.org ASAE ANSI/ASABE S660 September 2022Keywords: Distribution, Fertilizer, Granular, Pneumatic, Spreaders, Test 1 Purpose and Scope 1.1 Purpose. The purpose of this Standard is to establish a uniform method of determining and reporting spreading performance of large (18.3-m swath width or greater) broadcast spreaders and pneumatic applicators designed to surface apply granular materials. Results from tests performed according to this Standard make it possible to predict distribution uniformity of a particular broadcast spreader or pneumatic applicator or to compare the performance of different machines operated under similar test condition. 1.2 Scope. This Standard pertains to centrifugal, pendulum, pneumatic and other types of broadcast spreaders designed for dry granular product application while operating on common crop production field surfaces. Portions of the test procedures outlined herein are suitable for evaluating spread uniformity and spread width; however, additional tests not covered in this Standard are needed to completely evaluate the performance of gravity spreaders.
