34、for crop protection Spraying equipment Part 2: Test methods to assess the horizontal transverse distribution for hydraulic sprayers1 ScopeThis document is applicable for sprayers intended to apply liquid over a horizontal surface.This document specifies test methods to assess sprayed liquid horizont
35、al transverse distribution. Methods are based on sprayed liquid volume measurement, nozzle flow rate measurement or nozzle tip pressure measurement.This document does not cover aerial sprayers.Hydraulic sprayers use a range of design features to deliver and control spray. The test methods provided i
36、n this document are all useful but dont give the same information. They are complementary. Some test methods are not suitable for all sprayer types. Applicable test methods are described in an informative annex.2 Normative referencesThe following documents are referred to in the text in such a way t

In this case, a volume collected over measured time may be used.5 Test conditions5.1 GeneralThe sprayer is to be operated per sprayer manufacturers instructions. All operational conditions and test parameters shall be indicated in the test
42、 report. Clean water used for testing shall be free from solids in suspension.If an adjuvant, plant protection product or other chemical is added, its identity, properties and concentration shall be documented in the test report.5.2 Temperature and relative humidityThe temperature of the test liquid
43、 and the air temperature of the test premises shall be between 5 C and 35 C during the test.The temperature and the relative humidity of the test premises shall be stated in the test report. Relative humidity is recorded for information only.5.3 Choice of nozzles for the testsThe spray boom shall be
44、 equipped with nozzles, including nozzle filters and anti-drip devices, according to the relevant specifications provided by the sprayer manufacturers instruction manual. The nozzle type that is used shall be documented by nozzle manufacturer, model and size.Nozzle size may be chosen for very high f
45、low if the purpose of the evaluation is to determine maximum variation of the sprayer transverse distribution.Nozzle size may be chosen to provide lower flow, more representative of a common application practice.5.4 Control pressureThe control pressure is to be chosen according to the operating char
46、acteristic of the nozzle. During the test period, the pressure shall not deviate by more than 5 % from the intended pressure.The control pressure shall be stated in the test report.6 Test methods6.1 GeneralSprayed liquid volume horizontal transverse distribution (6.3), nozzle volume transverse distr
47、ibution (6.5), and nozzle tip pressure transverse distribution (6.6) are three methods that evaluate differently horizontal transverse liquid distribution.When nozzle volume or nozzle tip pressure methods are used to evaluate horizontal transverse liquid distribution, nozzle tip position, nozzle ori
48、entation (verticality of the nozzle and twist of the nozzle from perpendicular) and nozzle tip spray pattern of all nozzles shall also be verified. It shall also be verified that no objects occur in the sprayed liquid stream.For nozzle tip position requirements, see 6.4.Annex B identifies tests or t
49、est methods typically applicable to different sprayer types.2 ISO 2017 All rights reservedBS ISO 56822:2017ISO 5682-2:2017(E)Low flow rate measurements may not be possible directly with available flow meters.
