Standardization

In this ambit the activity of Crop Protection Technology Research Group is mainly addressed to develop and implement new standardized test methods and to design and set up the necessary test benches. In this view, the research group is involved in working groups ISO/TC 23/SC6 (Equipment for Crop Protection), CEN TC144/WG3 and in ENTAM (European Network for Testing of Agricultural Machines).

Among the ISO International Standards developed, under development and under revision/development with the contribution of the Crop Protection Technology Research Group there are:

• EN ISO 19932: Equipment for crop protection – Knapsack sprayers – Part 1: safety an environmental requirements; Part 2: Test methods
• EN ISO 28139: Equipment for crop protection – Knapsack combustion engine-driven air-blast sprayers – Safety and environmental requirements;
• ISO 12809: Crop protection equipment – Reciprocating positive displacement pumps and centrifugal pumps;
• ISO 22401: Equipment for crop protection – Method for measurement of potential spray drift from horizontal boom sprayers by the use of a test bench;
• EN ISO 16119: Agricultural and forestry machinery – Environmental requirements for sprayers; (parts 1, 2, 3, 4)
• EN ISO 16122: Agricultural and forestry machinery -Inspection of sprayers in use (parts 1, 2, 3, 4)
• ISO 22368: Crop protection equipment — Test methods for the evaluation of cleaning systems — Part 1: Internal cleaning of complete sprayers; Part 2: External cleaning; Part 3: Internal cleaning of tank
• ISO 21278: Equipment for crop protection — Induction hoppers – Part 1: Test methods; Part 2: General requirements and performances limits
• ISO 5682 Equipment for crop protection — Spraying equipment — Part 1: Test methods for sprayer nozzles; Part 2: Test methods to assess the horizontal transverse distribution for hydraulic sprayers; Part 3: Test method to assess the performance of volume/area adjustment systems; Part 4: Test Methods for Tank Agitation
• ISO 21191: Close transfer systems. Performance Specifications
• EN ISO 17962: Agricultural machinery – Equipment for sowing – Minimization of the environmental effects of fan exhaust from pneumatic systems

Among the EN Standards (CEN WG3) two new standards are under development :

• prEN 17745:2022 – Agricultural end forestry machinery: environmental requirements for granule applicators of Plant Protection Product;
• prEN 17744:2022 – Agricultural end forestry machinery: environmental requirements for dusters;

Among the UNI (Italian National Body for Standardization) Standards:

• UNI 11797: Macchine per la protezione delle colture – Metodologia di prova per la misura della deriva potenziale generata dalle macchine irroratrici per le colture arboree (Equipment for crop protection – Method for measurement of potential spray drift from tree crop sprayers)
