DANSK DS/ISO 22369-2 PDF

This part of ISO 22369 specifies the drift classification procedure for field crop sprayers by field measurements of spray drift sedimentation according to ISO 22866 including the test methods and evaluation criteria needed and allows the allocation of the spray drift reduction classes specified by ISO 22369-1. The object of of this part of ISO 22369 is to determine the drift reducing performance of field crop sprayers by comparison with a reference spray system in order to rate (classify) the field crop sprayers. The application of this International Standard may support advisory services for farmers, the product development and legal certification and classification schemes. This part of ISO 22369 is intended to be used together with ISO 22369-1. This International Standard is applicable to mounted, trailed and self-propelled field crop sprayers used in field crops.
