DIN EN ISO 17962:2015-12

This International Standard specifies various means of minimizing the environmental effects of fan exhaust from pneumatic systems for vacuum-style sowing agricultural field equipment used for sowing coated seeds. It is applicable to vacuum-style sowing systems where "dust off" (fugitive) material from seed coatings can mix with fan (blower) intake air and be exhausted into the atmosphere. This International Standard is not applicable to: - conveyance systems between a central tank and remote meters where the air is exhausted at the remote meters; and - conveyance systems where the meter is at a central tank and the air is exhausted at a ground engaging opening device. The design principles in this International Standard are not applicable to pneumatic equipment for sowing which was manufactured before the date of its publication. This standard contains the German version of ISO 17962:2015 prepared by Technical Committee ISO/TC 23 "Tractors and machinery for agriculture and forestry" in collaboration with Technical Committee CEN/TC 144 "Tractors and machinery for agriculture and forestry" at the European Committee for Standardization (CEN). The national interests during the preparation were represented by Working Committee NA 060-16-02 "Bodenbearbeitung, Saat, Pflanzenpflege und Pflanzenschutz" ("Soil cultivation, seeds, plant care and plant protection") at DIN Standards Committee Mechanical Engineering (NAM). Representatives of the interested parties were involved in the preparation of this standard.
