17、s document (EN 13790-2:2003) has been prepared by Technical Committee CEN/TC 144 “Tractors and machinery for agriculture 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 or by
18、 endorsement, at the latest by November 2003, and conflicting national standards shall be withdrawn at the latest by November 2003. This standard consists of the following parts, under the general title Agricultural machinery Sprayers - Inspection of sprayers in use: ? Part 1: Field crop sprayers ?
19、Part 2: Air-assisted sprayers for bush and tree crops Annexes A and B are informative. During recent years, several countries have developed systems for inspection of air-assisted sprayers for bush and tree crops in use. Developments in this direction have been stimulated by public concern about ris
20、ks, and the aim of reducing the use of crop protection products. However, there are three main arguments for the inspection: ? test operator safety (minimum requirements are given concerning operator safety in the use of work equipment at work directive 95/63/CE, amending directive 89/655/CEE, and c
21、an be complimented by national regulations); ? less potential risk of environmental contamination by crop protection products; ? good control of the pest with the minimum possible input of crop protection product. As the third argument above indicated, tests of sprayer function are of great importan
22、ce for the efficiency of the treatment which consequently can also be very profitable for the user of the sprayer. In order to use crop protection products in agricultural production in Europe safely, it is necessary to define the requirements and test methods for sprayers in use. This is a relevant
23、 step after having standardized the requirements for new equipment, in respect of safety hazards (see EN 907) and potential risks of environmental contamination (see EN 12761 Parts 1 to 3). According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following count
24、ries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and the United Kingdom.

26、re and maintenance. This is the logical link between new equipment of good quality and well educated and concerned users. The inspection of sprayers in use can be done on a voluntary or mandatory basis. In both cases further official or legal specifications are necessary, e.g. on the execution manag
27、ement of the inspection, which organizations are authorized to carry out the inspection, time intervals between inspections etc. As the specifications of this European Standard are based on EN 907 and EN 12761, it may be the case that sprayers in use which were produced before EN 907 and EN 12761 ca
28、me into force do not fulfil all the specifications given in this European Standard. 1 Scope This European Standard specifies the requirements and methods of their verification for the inspection of air- assisted sprayers for bush and tree crops in use. It relates mainly to the condition of the spray
29、er in respect of safety hazards for the test operator, the potential risk of environmental contamination and opportunities to achieve good application. NOTEMinimum requirements are given concerning operator safety in the use of work equipment at work directive 95/63/CE, amending directive 89/655/CEE
30、, and can be complimented by national regulations. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For d
31、ated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments). EN 837-1, Pressure gauge

33、y inspection, function tests and measurements. NOTESome of the tests specified in this standard involve processes which could lead to a hazardous situation. Any person performing tests in accordance with this standard should be appropriately trained in the type of work to be carried out. All nationa
