ISO/FDIS 16122-4:2014(E)IntroductionThere are two main reasons for the inspection: less potential risk of environmental contamination by plant protection productsâ— good control of the pest with the minimum possible input of plant protection product.In order to use plant protection products in agricultural production safelyá it is necessary to de Ðine the requirements and test methods for sprayers in useä This is a relevant step after having standardized
v t w væ xrisks of environmental contamination (see ISO 16119 series).Standardising the requirements and methods for inspection of sprayers in useá takes into consideration not only the original performance of the sprayerá but also its useá care and maintenanceä This is a logical link to ensure the continued bene Ðit arising from the supply of new sprayers of good qualityäThe inspection of sprayers in use can be a mandatory requirement or adopted on a voluntary basisä In both cases further requirementsá outside the scope of this standardá are necessary for the management of inspectionsä These includeá for exampleá requirements for the competence of persons carrying out inspections and the frequency of inspectionsäNOTE National or local regulations may also apply concerning the quali Ðications and competence of inspectors. vi © ISO 2014 – All rights reservedkSIST FprEN ISO 16122-4:2014
