3、ord IS.0 (the International Organization for Standardization) is a worldwide federation 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 techn
4、ical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
5、electrotechnical standardization. Draft International Standards adopted by the technical 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 pr

9、license from IHS -,-,- INTERNATIONAL STANDARD 0 IS0 IS0 13440: 1996(E) Equipment for crop protection - Agricultural sprayers - Determination of the volume of total residual 1 Scope This International Standard specifies the test method for the determination of the volume of total residual for mounted
10、, trailed and self-propelled agricultural sprayers 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
11、with the intended application rate and/or pressure, 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 dea
12、d volume; non dilutible volume Part of the total residual 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 a
13、nd horizontal position. The pump shall be driven 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. 3.2 The pressure shall be set such that the average liquid output of
14、 the nozzles is : a) 1 I/min for pneumatic sprayers; b) 2 I/min for field crop sprayers and vineyard sprayers; c) 4 I/min for orchard sprayers; d) 6 I/min for hop plantation sprayers. NOTE -The output values given are for the normal case but other values can be used for particular cases. The liquid
15、output of each nozzle shall be adjusted with an accuracy off 0,i I/min. The spray tank shall be half full or contain, at most, 500 I. The liquid used shall be water. 1 Copyright International Organization for Standardization Provided by IHS under license with ISO Licensee=NASA Technical Standards 1/

Set the pressure and the liquid nozzle output in ac
17、cordance 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
18、 tank and the dead volume, to an accuracy of 0,1 % 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. NOTE -Alternatively, instead of measuring the volume of the residual, the sprayer can be weighecl after t
