Land- und Forstmaschinen - Pflanzenschutzgeräte zum Ausbringen von Pflanzenschutzmitteln und flüssigen Düngemitteln - Umweltschutz - Teil 2: Feldspritzgeräte
Diese Norm beschreibt Anforderungen an die Konstruktion und Leistung von Feldspritzgeräten hinsichtlich der Reduzierung von möglichen Gefährdungen für die Umwelt und legt deren Überprüfung fest.
Dieser Teil gilt in Verbindung mit EN 12761-1:2001, der generelle Leitlinien für landwirtschaftliche Pflanzen-schutzgeräte enthält.
ANMERKUNG Die Anforderungen basieren auf den Prüfmethoden nach ISO 5682-2, die insbesondere für Geräte mit hydraulischer Zerstäubung entwickelt wurden. Für andere Zerstäubungsarten können andere Prüfmethoden und/oder
-kriterien erforderlich sein. Dies ist Gegenstand einer künftigen Untersuchung und einer möglichen Ergänzung dieser Norm.
Matériel agricole et forestier - Pulvérisateurs et distributeurs d'engrais liquide - Protection de l'environnement - Partie 2: Pulvérisateurs pour cultures basses
1 Domaine d'application
La présente norme établit les prescriptions et les méthodes de vérification correspondantes pour la conception et les performances des pulvérisateurs pour cultures basses dans l'objectif de réduire les risques de contamination de l'environnement.
Cette partie s'applique avec le EN 12761-1:2001 qui contient des lignes directrices générales applicables aux pulvérisateurs agricoles.
NOTE Les prescriptions s'appuient sur les méthodes d'essai figurant dans l'ISO 5682-2, développées principalement pour les pulvérisateurs à jet projeté. Pour d'autres pulvérisateurs, d'autres méthodes d'essai et/ou critères d'acceptation peuvent être nécessaires. Ceci fera l'objet d'une étude ultérieure et d'un éventuel amendement à cette norme.

100 m as specified in ISO 4287,and measured according to ISO 4288.4.1.1.2 FillingFilling devices shall be designed to avoid any return of liquid from the tank to the filling supply.The filling hole diameter shall comply with ISO 9357. 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)lMinimum depth 1) (d)mmC

The volume of total residual shall be determined in accordance withISO 13440.An emptying device in accordance with 4.5.3 of EN 907:1997 shall allow the complete emptying of the residual inthe tank when the sprayer is in a horizontal position. Complete emptying of the residual is achieved if there are novisible puddles at the bottom of the tank after 5 min drainage.It shall be possible to collect the liquid at the outlet without contaminating the operator or equipment parts, e. g.stays.The tank outlet shall be guarded against accidental opening.4.1.1.4 Tank contents indicatorThe indication of contents shall correspond to ISO 9357. It shall be durable and easily visible from the driver'sposition and from where the tank is filled.The acceptable tolerances of the indication are :a)
7,5 % for each graduation mark for volumes up to 20 % of the nominal tank volume ;b)
5 % for each graduation mark for volumes above 20 % of the nominal tank volume.The tolerances shall be measured with a maximum error on measurement of
1 % with the sprayer in ahorizontal position.Other means of visually checking the contents of the tank are allowed if they achieve equivalent accuracy.SIST EN 12761-2:2001

The maximumallowable deviation is ± 15 % when tested in accordance with ISO 5682-2.4.1.2 Hoses and linesThe bending radius of hoses shall be within limits recommended by the hose manufacturer. Hoses shall
not haveany deformation which can disturb the liquid flow.Pressure lines shall be equipped with quick-acting shut-off valves (e.g. tip-over lever valves).4.1.3 Spray boom4.1.3.1 Working and spraying section widthsThe working width shall correspond to the usual widths of seed drills, cultivators, etc. and shall be a whole-number multiple of these.NOTEFor information, see ISO 6720 which specifies the recommended working widths for sowing, planting, distributingfertilizers and spraying.The maximum section widths are: 4,5 m for boom width
24 m; 6,0 m for boom width > 24 m.It shall be possible to use any individual boom section when required.4.1.3.2 AdjustmentThe adjustment range for the spray boom height shall be at least 1,0 m.It shall be possible to adjust the minimum distance between the nozzles and the target according to the nozzlecharacteristics. For sprayers that are to be used in crops higher than 1,0 m,
the adjustment range of the boomheight shall be at least 1,2 m.For sprayers with a maximum boom width of 21 m, it shall be possible to adjust the distance between the nozzlesand ground down to at least 0,5 m.The boom height shall be adjustable either continuously or by increments not exceeding 0,1 m.Regardless of the distance of the boom above the ground, no liquid shall be sprayed on to the sprayer itself. Thisdoes not apply to components of the sprayers (e.g. sensors) which in order to function are necessarily in contactwith the mixture. In these cases, however, dripping shall be minimized.For spray booms with a working width of more than 13 m, boom movements independent of the sprayer (e.g.pendulum) shall ensure that the boom can be positioned parallel to the ground.4.1.3.3 Contact with obstaclesSpray booms with a working width up to 10 m shall be able to move backwards in case of contact with obstaclesin the field. This requirement shall be checked by moving the sprayer forwards at a speed of 4 km/h
0,2 km/hwith the obstacle placed within 90% to 100 % of the half working-width of the boom, measured from the middle ofthe track (see Figure 2). The spray boom shall be able to give way without being damaged.SIST EN 12761-2:2001
