International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrot

14、rs used for crop protection and fertilization. 2 Definitions For the purposes of this International Standard, the following definitions apply: 2.1 volume of total residual volume of the spray mixture remaining in the sprayer which cannot be delivered with the intended application rate and/or pressur

15、e, equal to the sum of the volume of residual tank and the dead volume 2.2 volume of residual in the tank; dilutible volume part of the total residual that remains in the tank or that can flow back to the tank during normal sprayer operation 2.3 dead volume; non dilutible volume part of the total re

16、sidual that cannot flow back to the tank during normal operation of the sprayer 2.4 horizontal position normal operating position of the sprayer on level ground 3 General 3.1 The test shall be carried out with the sprayer secured in a stationary and horizontal position. The pump shall be driven at n

17、ominal speed. The spray boom including liquid lines and nozzles shall be in working position. The boom shall be equipped with one size of nozzles recommended by the manufacturer. 3.2 The pressure shall be set such that the average liquid output of the nozzles is: a) 1 l/min for pneumatic sprayers; b

18、) 2 l/min for field crop sprayers and vineyard sprayers; c) 4 l/min for orchard sprayers; d) 6 l/min for hop plantation sprayers. NOTEThe output values given are for the normal case but other values can be used for particular cases. The liquid output of each nozzle shall be adjusted with an accuracy

19、 of 0,1l/min. The spray tank shall be half full or contain, at most,500l. The liquid used shall be water. 4 Procedure 4.1 On level ground Secure the sprayer in a horizontal position and in accordance with3.1. Set the pressure and the liquid nozzle output in accordance with3.2. Refill the amount of w

20、ater to be in accordance with3.2 and start the test. Let the sprayer discharge the water until the first pressure drop of25% for1s occurs. Then immediately stop the sprayer and measure the volume of the residual. Measure the volume of residual in the the tank and the dead volume, to an accuracy of0,

21、1% of the nominal tank volume. Repeat the measurement and record the average of the two measurements as the value of the volume of total residual. NOTEAlternatively, instead of measuring the volume of the residual, the sprayer can be weighed after the test and after the total discharge of the spraye

22、r. The residual volume can then be calculated. 4.2 On slopes 4.2.1 8,5 slope The sprayer shall be inclined to the left and to the right, to the front and to the rear at an angle of8,5 0,5 . In each of these positions, determine the volume of residual in the tank and the dead volume as stipulated in4

23、.1. 4.2.2 Maximal slope Optionally, an additional determination can be performed at an angle corresponding to the maximum slope recommended by the manufacturer. 5 Test report The test results shall be recorded in a test report which conforms toAnnex A.BS6356-11:1997 2 BSI 09-1999 Annex A (normative)
