ISO 17962:2015 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.
ISO 17962:2015 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 exhaust 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.
NOTE National or local requirements can apply which could be more stringent.
