Measuring and recording shall continue after adjustments until a steady-state of the system is achieved.Stationary tests are allowed for sprayers or laboratori

36、es where the driving speed can be simulated (e.g. sprayers with flow check modes, laboratories with a method of providing simulated speed to the wheels or control system).4.2.2 At the start of the measurements defined in 5.2 and 5.3, the following sprayer settings shall apply:a) nominal driving spee

37、d vN: 4 kmh1, 6 kmh1, 8 kmh1, 16 kmh1or 24 kmh1, according to the relevant local practice and regulations;b) nominal rotational frequency nNof the pumps:1) for pumps driven by power take-off (PTO) according to:i) a PTO rotational frequency of 400 min1, if nominal rotational PTO frequency is 540 min1

38、; ii) a PTO rotational frequency of 800 min1, if nominal rotational PTO frequency is 1 000 min1;iii) a PTO rotational frequency of 75 % of the nominal rotational PTO frequency, if this deviates from 540 min1or 1 000 min1.2) for pumps not driven by a PTO of the tractor or carrier vehicle (e.g. hydrau

39、lic driven) according to an engine rotational frequency of 75 % of rated engine speed.c) a nominal volume/area rNaccording to the relevant Good Agricultural Practice and local regulations.4.2.3 If the pump drive is independent of engine rotational frequency (e.g. pumps driven by the hydraulic system

40、 of the tractor) or if the driving speed is not controlled by engine rotational frequency (e.g. hydrostatic transmission or variable transmission), variation of the speed (5.3.2.) is not necessary.4.3 Measuring equipmentSee ISO 5682-1.5 Test procedure5.1 GeneralThe tests shall be made on a stationar

41、y sprayer. If the volume/area adjustment system does not provide a driving speed simulation mode, the driving speed shall be simulated with the help of a function generator. Its frequency shall be adjustable in conjunction with the pump rotational frequency or separately.Preferably, a flow meter acc

42、ording to 4.3 shall be used for the measurements. If the measurements are performed using a pressure indicator, the relation between volumetric flow rate and spray pressure shall be determined prior to the measurements using the method provided in ISO 5682-2:2017, 6.5. The pressure shall be measured

43、 downstream of any central pressure filter. If other parameters are used to control the flow rate, they shall be substituted in place of the term “pressure”.For all measurements, the volumetric flow rate shall be recorded with a minimum sample rate of 10 measurements per second.2 ISO 2017 All rights
