11、ISO 22369-2:2010(E) ISO 2010 All rights reserved iiiForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Ea

12、ch member body interested in a subject for which a technical 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. ISO collaborates closely with the Internatio

13、nal Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standar

14、ds 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. Attention is drawn to the possibility that some of the elements of this document may be the subject

15、of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 22369-2 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and forestry, Subcommittee SC 6, Equipment for crop protection. ISO 22369 consists of the following par

16、ts, under the general title Crop protection equipment Drift classification of spraying equipment: Part 1: Classes Part 2: Classification of field crop sprayers by field measurements The following part is under preparation: Part 3: Potential spray drift measurement for field crop sprayers by the use

17、of a test bench BS ISO 22369-2:2010ISO 22369-2:2010(E) iv ISO 2010 All rights reservedIntroduction ISO 22369 (all parts) specifies the drift classification of spraying equipment. ISO 22369-1 defines the spray drift reduction classes. The other parts of ISO 22369 specify the test procedures and, ther

18、efore, ISO 22369-1 is intended to be used in combination with one of the other parts of ISO 22369. Spray drift of plant protection products can contaminate non-target or sensitive areas, such as surface water hence minimum spray distances or buffer zones, are often specified. Using sprayers and/or s

19、prayer parts, which reduce levels of spray drift, can enable these distances to be reduced. Drift classification procedures for sprayers and sprayer parts facilitate decision making by the farmer and can be of interest in defining best practice or for regulation/legislation. Spray drift can occur as

20、 airborne drift and ground sedimentation of drift fallout. Classification in this part of ISO 22369 is based on the comparison of levels of ground sedimentation from spraying equipment (for example sprayers or parts of sprayers) with reference spraying systems based on the use of spraying equipment

21、according to good agricultural practice for plant protection in different regions and crops. Spray drift deposition or collection is measured at different distances from the target area and the drift reducing performance of the spraying equipment is rated against a reference spraying system. The obj

22、ect of ISO 22369 (all parts) is to provide uniform procedures for the determination of the drift reducing performance of spraying equipment.

23、t Part 2: Classification of field crop sprayers by field measurements 1 Scope This part of ISO 22369 specifies the drift classification procedure for field crop sprayers by field measurements of spray drift sedimentation in conformity with ISO 22866, including the test methods and evaluation criteri

24、a needed. It also allows the allocation of the spray drift reduction classes specified by ISO 22369-1. This part of ISO 22369 is intended to determine the drift reducing performance of field crop sprayers by comparison with a reference spraying system in order to rate (classify) the field crop spray

25、ers. The application of this part of ISO 22369 can support advisory services for farmers, product development and legal certification and classification schemes. This part of ISO 22369 is intended to be used together with ISO 22369-1. This part of ISO 22369 is applicable to mounted, trailed and self

26、-propelled field crop sprayers used in field crops. 2 References The following referenced documents are indispensable for the application of this document.

28、 purposes of this document, the terms and definitions given in ISO 22369-1 and ISO 22866 and the following apply. 3.1 zone 1 1 m to 5 m zone zone which is downwind and adjacent to the directly sprayed zone and which is at a distance of between 1 m and 5 m from the directly sprayed zone See Figure 1.

29、 3.2 zone 2 to zone 10 5 m to 10 m zone to 45 m to 50 m zone zones which are downwind and further away from the directly sprayed zone, and which are 5 m apart and between 5 m and 50 m from the directly sprayed zone See Figure 1. 3.3 zone 11 zone which is downwind and used for assessing the drift, wh

30、ich consists of one specific, several or all zones from zone 1 to zone 10 and which is at a distance of 1 m up to 50 m from the directly sprayed zone For the 1 m to 50 m example, see Figure 1.

32、equipment (field crop sprayer to be specified) with the reference spraying system (see 5.2). The classification may include classes A to F (see ISO 22369-1) and may be done for one, several or all zones specified in Figure 1. The classification of the spraying equipment depends on the amount of redu

33、ction in soil sediments of the spray drift determined by field measurements (see 5.1), compared with the spray drift deposition of the reference spraying system (see 5.2), in a comparative measurement at the same time and weather and crop condition. The classification is based on the evaluation (see

34、 5.3). 5 Drift classification procedure 5.1 Measurements The measurements shall be carried out in accordance with ISO 22866 and downwind from the edge of the directly sprayed zone. The soil sediments shall be measured in one, several or all zones specified in Figure 1 and at least at the distances t

35、o the directly sprayed zone shown in Table 1. NOTE Additional zones can be added in case of special interests.

37、 (as given in Table 2), crop-related data (as given in Table 3) and meteorological data (as given in Table 4). The crop-related data shall be the same and the meteorological data shall be as similar as practicable for the candidate and the reference spraying equipment and shall be specified. Due to

38、the different good agricultural practices for plant protection in different regions and crops, the modification of the reference spraying system may be necessary. However, to allow international comparison of measurements, any classification scheme shall include data derived with the equipment as gi

39、ven in Table 2. NOTE The comparison of classification is limited due to differences in the reference spraying system caused by variation in crop-related data and metrological data.
