Page 3EN 12761-3:2001ForewordThis European Standard has been prepared by Technical Committee CEN/TC 144 "Tractors and machinery foragriculture and forestry", the secretariat of which is held by AFNOR.This European Standard shall be given the status of a national standard, either by publication of an identical text orby endorsement, at the latest by September 2001, and conflicting national standards shall be withdrawn at thelatest by September 2001.This standard consists of the following parts, under the general title Agricultural and forestry machinery – Sprayersand liquid fertilizer distributors – Environmental protection: Part 1 : General Part 2 : Field crop sprayers Part 3 : Air-assisted sprayers for bush and tree cropsAccording to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden,Switzerland and the United Kingdom.SIST EN 12761-3:2001



Page 4EN 12761-3:20011 ScopeThis standard specifies requirements and methods for their verification for design and performances of air-assistedsprayers for bush and tree crops with respect to minimizing the risk of environmental contamination.This part applies in connection with
EN 12761-1:2001 which contains general guidelines for agricultural sprayers.2 Normative referencesThis European Standard incorporates, by dated or undated reference, provision from other publications. Thesenormative references are cited at the appropriate places in the text and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision.

The opening lid shall be tightly sealed to avoid spillage.The total tank volume shall be at least 5 % more than its nominal volume. Tanks with nominal volume greaterthan 200 l shall have a nominal volume which is a multiple of 100 l.Strainers shall have a minimum depth d as given in Table 1 and measured according to Figure 1.Strainers shall be installed in filling openings and shall have a mesh size less than 2 mm. Also any gap(s)between the tank filling hole and the strainer shall not exceed 2 mm (see Figure 1).The filling capacity of the tank with strainer when filled with water shall be at least 100 l/min for tanks with anominal volume of 100 l or more. For tanks with a nominal volume less than 100 l, it shall be possible to fill thetank within 1 min.Strainers of the chemical introduction bowl, if available, shall have a filter with a maximum mesh size of 20 mm.Table 1 — Minimum depth of strainersNominal tank capacity (C)Minimum depth 1)(d)lmmC
