5、ration of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that commi
6、ttee. International organizations, governmental and non-governmental, in liaison with ISO, also take pari in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the te
7、chnical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard IS0 13440 was prepared by Technical Committee ISOTTC 23, Tractors and machinery for agriculture a
8、nd forestry, subcommittee SC 6, Equipment for crop protection. Annex A forms an integral pari of this International Standard. 1 Scope This International Standard specifies the test method for the determination of the volume of total residual for mounted, trailed and self-propelled agricultural spray
9、ers 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
10、e, equal to the sum of the volume of residual tank and the dead volume. 2.2 Part of the total residual that remains in the tank or that can flow back to the tank during normal sprayer operation. 2.3 Part of the total residual that cannot flow back to the tank during normal operation of the sprayer.
11、2.4 horizontal position Normal operating position of the sprayer on level ground. volume of residual in the tank; dilutible volume dead volume; non dilutible volume 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
12、at nominal 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. Page 2 IS0 13440 : 1996 3.2 The pressure shall be set such that the average liquid output of the nozzles is : a) 1 I/
13、min for pneumatic sprayers; b) 2 I/min for field crop sprayers and vineyard sprayers; c) 4 Vmin for orchard sprayers; d) NOTE -The 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 of I0,
14、l Vmin. 6 I/min for hop plantation sprayers. The spray tank shall be half full or contain, at most, 500 I. The liquid used shall be water. 4 Procedure 4.1 On level ground Secure the sprayer in a horizontal position and in accordance with 3.1. Set the pressure and the liquid nozzle output in accordan
15、ce with 3.2. Refill the amount of water to be in accordance with 3.2 and start the test. Let the sprayer discharge the water until the first pressure drop of 25 % for 1 s occurs. Then immediately stop the sprayer and measure the volume of the residual. Measure the volume of residual in the the tank
16、and the dead volume, to an accuracy of 0,l Yo of the nominal tank volume. Repeat the measurement and record the average of the two measurements as the value of the volurne of total residual. NOTE - Alternatively, instead of measuring the volume of the residual, the sprayer can be weighed after the t
17、est and after the total discharge of the sprayer. 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 of 8,5“ f 0,5“. In each of these positions, determine the volume of residu
18、al in the tank and the dead volume as stipulated in 4.1. 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 to an
