DIN EN ISO 16122-4:2015-10 EN ISO 16122-4:2015 (E) 4IntroductionThere are two main reasons for the inspection: less potential risk

31、 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 products in agricultural production safely, it is necessary to define the requirements and test methods for sprayers in

32、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 contamination (see ISO 16119 series).Standardising the requirements and methods for inspection of sprayers in use, takes in

33、to 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 supply of new sprayers of good quality.The inspection of sprayers in use can be a mandatory requirement or adopted on a v

34、oluntary basis. In both cases further requirements, outside the scope of this standard, are necessary for the management of inspections. These include, for example, requirements for the competence of persons carrying out inspections and the frequency of inspections.NOTE National or local regulations

35、 may also apply concerning the qualifications and competence of inspectors.DIN EN ISO 16122-4:2015-10EN ISO 16122-4:2015 (E)51 ScopeThis part of ISO 16122, when used together with ISO 16122-1, specifies the requirements and test methods for the inspection of fixed and semi-mobile sprayers, when in u

36、se.The requirements relate mainly to the condition of the sprayer with respect to its potential risk for the environment and its performance to achieve good application.It does not apply to application equipment for spatial treatment (e.g. foggers).NOTE Requirements for the protection of inspectors

37、during an inspection are given in ISO 16122-1.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

42、pelineSOURCE: ISO 16119-4:2014, 3.44 Requirements and method of verification4.1 Leaks and dripping4.1.1 Static leaksThe sprayer shall be filled with water to its nominal capacity.With the pump not running and the sprayer parked on a level horizontal surface (in case of semi-mobile sprayer), a visual

43、 inspection 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 othe

44、r damage that 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

45、part of the 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

46、 no leakage 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

47、 sprayer itself (e.g. parts of the sprayer, hoses). 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.

49、.1.3 Other sprayersa) The pump capacity shall be at least 90 % of its original nominal flow given by the sprayer manufacturer or another minimum pump capacity given by the sprayer manufacturer.Compliance shall be checked by measurement according to 5.2.1.2.3;or for sprayers not fitted with a test adapter:b) The pump(s) shall have sufficient flow rate capacity in order to be able to spray while maintaining a visible agitation as specified in 4.3.1.
