7、d. This standard contains specifications meeting the essential requirements set out in Annex I of the “Machinery Directive”, Directive 2006/42/EC, and which apply to machines that are either first placed on the market or commissioned within the EEA. This standard serves to facilitate proof of compli
8、ance with the essential requirements of that directive. Once this standard is cited in the Official Journal of the European Union, it is deemed a “harmonized” standard and thus, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (“presumption
9、 of conformity”). The International Standards referred to in this document and taken over as European Standards have been published as the corresponding DIN EN ISO Standards with the same number. Where the International Standards and documents referred to are not also DIN ISO Standards with the same
10、 number, there are no national standards available. This document supersedes DIN EN ISO 19932-2:2014-02. Amendments Compared with DIN EN ISO 19932-2:2014-02 the following corrections have been made to the German version only: a) some changes have been made to the text to adjust the German translatio

38、 The device shall not affect the impact force of the dropped sprayer. An example is given in Annex D. Other devices with equivalent performance can be used.4.6 Filling device, by which the volume and flow of water or test liquid can be controlled and adjusted. An example is given in Annex E. Other d
39、evices with equivalent performance can be used.4.7 Weighing devices, with the ability to weigh up to:a) 25 kg with a maximum error of 1 g;b) 2 kg with a maximum error of 0,1 g.4.8 Measuring cylinder, for measuring volumes of up to 1 l with a maximum error of 10 ml.4.9 Timer (stop watch), with a maxi
40、mum error of 0,5 s for measuring periods up to 5 min.4.10 Pressure supply device, to place the sprayer under pressure using air or water. The pressure shall be adjustable up to 10 bar with a maximum error of 5 % of the measured value.4.11 Pressure gauges, to measure between 0 bar and 25 bar with a m
41、aximum error of 0,15 bar (equivalent to a class 0,6 pressure gauge according to EN 837-1).4.12 Polythene bags, the size of which shall be at least 30 cm x 40 cm.4.13 Polythene sheets, the size of which shall be at least 2 m x 1 m.5 General5.1 Test conditionsThe tests shall be performed with one new
42、specimen of the sprayer type at an air temperature of 10 C to 30 C and relative air humidity of at least 30 %, with no influence of wind or sunlight.5.2 SprayerAssemble the knapsack sprayer in accordance with the instruction handbook. Inspect for tightness of the filling cap, gland nut and other ope
43、rator controlled couplings. Weigh the complete empty sprayer using a weighing device 4.7 a) and record the mass in kilograms.5.3 Functional tests5.3.1 Shut-off device reliabilityDetach the shut-off device assembly with the spray lance from the sprayer and mount it on a frame (4.3). Connect the shut-
44、off device to a pressurized water supply of (3 0,2) bar. Fully activate the shut-off device using a frequency of (15 5) cycles/min for a total duration of 25 000 cycles. Inspect functionality and record any leakage occurring within 1 min 5 s after completion of the last cycle.5.3.2 Spray liquid outp
45、utThe spray liquid output rate qmof the sprayer for each combination of nozzle/pressure regulator supplied for use with the sprayer shall be measured with a maximum error of 1 % at the optimum spray pressure specified in the instruction handbook or at the setting specified in the instruction handboo

47、ement of risk. All personnel shall either be kept out of the test area or otherwise protected from hazards such as parts displaced from the sprayer on test.Fill the spray tank with water so that the total mass of the sprayer is 7 kg 10 g. If the empty mass of the sprayer is over 7 kg the test shall
48、be carried out with the sprayer empty and if the maximum mass of the sprayer filled to the nominal volume is below 7 kg record the mass and test at this mass. Attach the sprayer to a strap test device (4.4) so that each load carrying strap can be tested individually. From the position where the spra
49、yer is carried by a strap in the device, lift the sprayer vertically (200 20) mm and let the sprayer drop. Repeat this 10 times for each load carrying strap.Inspect for damage.5.3.4 StabilityPosition the empty sprayer on a flat hard surface with an incline of 8,5 0,2 so that the load carrying straps are facing down the slope.
