26、edBS EN ISO 16122-4:2015ISO 16122-4:2015(E)IntroductionThere are two main reasons for the inspection: less potential risk of environmental contamination by plant protection products; good control of the pest with the minimum possible input of plant protection product.In order to use plant protection

27、 products in agricultural production safely, it is necessary to define the requirements and test methods for sprayers in use. This is a relevant step after having standardized minimum requirements for new sprayers, in respect of safety hazards (see ISO 4254-6) and potential risks of environmental co

28、ntamination (see ISO 16119 series).Standardising the requirements and methods for inspection of sprayers in use, takes into consideration not only the original performance of the sprayer, but also its use, care and maintenance. This is a logical link to ensure the continued benefit arising from the

29、supply of new sprayers of good quality.The inspection of sprayers in use can be a mandatory requirement or adopted on a voluntary basis. In both cases further requirements, outside the scope of this standard, are necessary for the management of inspections. These include, for example, requirements f

30、or the competence of persons carrying out inspections and the frequency of inspections.NOTE National or local regulations may also apply concerning the qualifications and competence of inspectors.vi ISO 2015 All rights reservedBS EN ISO 16122-4:2015Agricultural and forestry machines Inspection of sp

39、 for any leakage from the tank, pump and associated pipes shall be carried out.For high capacity tanks, water filling can be reduced to no less than half of the nominal tank volume, provided an additional inspection of the tank is carried out in order to identify any cracks, holes or other damage th

40、at can cause leakage.Compliance shall be checked by inspection.4.1.2 Dynamic leaks4.1.2.1 Leak-test when not sprayingWith the sprayer running at a pressure which is equal to the maximum obtainable pressure for the system, with the section valves closed, there shall be no leakage from any part of the

41、 sprayer.Compliance shall be checked by inspection.4.1.2.2 Leak-test while sprayingWhile spraying at a pressure that is equal to the maximum working pressure recommended by the sprayer manufacturer, or the nozzle manufacturer for the nozzles mounted on the sprayer if lower, there shall be no leakage

42、 from any part of the sprayer.Compliance shall be checked by inspection.4.1.3 Spraying and dripping on partsRegardless of the distance between the spray boom to the target to be sprayed, in the range between the nozzles and the target surface, no liquid shall be sprayed directly on to the sprayer it

This does not apply if needed by function (e.g. sensors) and if dripping is minimised.Compliance shall be checked by inspection and function test.4.2 Pump(s)4.2.1 Capacity4.2.1.1 GeneralThe pump capacity shall be suited to the needs of the sprayer.2 ISO 2015
