The work of preparing International Standards is normally carried out through IsO technical committees. Each member body interested in a subject for which a technical committee has been established has liaison with IsO, also take part in the work. IsO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of 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 ISO 13440 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and forestry, subcommittee Sc 6, Equipment for crop protection.

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 /min for pneumatic sprayers; c) 4 /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 output of each nozzle shall be adjusted with an accuracy of ± 0,1 /min. The spray tank shall be half full or contain, at most, 50o I. The liquid used shall be water. Copyright lr Noreproductionornetworking permited without licensefromH Not for Resale
