An important part of agricultural equipment development and innovation is standardization.  Equipment manufacturers rely heavily on national and international standards to develop machines that are safe, reliable, and compatible with other machines developed by different manufacturers.  A new national standard was developed to prescribe methods to test the accuracy of granular application machinery.  This work has a direct impact on anyone who purchases agricultural granular application equipment.  It will ensure that the machines have been tested in accordance with a given standard so that they can be assured of a certain level of performance from the machines that they buy.
