This European Standard shall be given the status of a nat
16、ional standard, either by publication of an identical text or by endorsement, at the latest by November 2003, and conflicting national standards shall be withdrawn at the latest by November 2003. This European Standard consists of the following Parts, under the general title Agricultural machinery S
17、prayers - Inspection of sprayers in use: ? Part 1: Field crop sprayers ? 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 field crop sprayers in use. Developments in this direction h
18、ave been stimulated by public concern about risks, 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
19、 95/63/CE, amending directive 89/655/CEE, and can 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. In order to use crop protection product
20、s in agricultural production in Europe safely, it is necessary to define the requirements and test methods for sprayers in use. This is a relevant step after having standardized the requirements for new equipment, in respect of safety hazards (see EN 907) and potential risks of environmental contami
21、nation (see EN 12761 Parts 1 to 3). According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland
22、, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and the United Kingdom. EN 13790-1:2003 (E) 4 Introduction Standardising the requirements and methods for inspection of sprayers in use, takes into consideration not only the original performance of the s
23、praying equipment, but also its use, care 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
24、 necessary, e.g. on the execution management of the inspection, which organisations are authorised 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
25、 produced before EN 907 and EN 12761 came 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 field crop sprayers in use. It relates mainly to the condition
26、of the sprayer 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 directiv
27、e 89/655/CEE, 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 here
28、after. For dated 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, Pr

30、be checked by 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.
31、 All national regulatory conditions and health and safety requirements should be followed.

35、ump capacity shall be suited to the needs of the equipment. a) The pump capacity shall be at least 90 % of its original nominal flow, given by the manufacturer of the sprayer. Method of verification: measurement according to 5.2.1.a); or b) the pump shall have sufficient flow rate capacity in order
36、to be able to spray at maximum working pressure as recommended by the sprayer or the nozzle manufacturer during test with the largest nozzles mounted on the boom while maintaining a visible agitation as specified in 4.3.
