17、 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of an identical text or by endorsement, at the latest by November 2003, and conflicting national standards shall be withdrawn at the l
18、atest by November 2003. This European Standard consists of the following Parts, under the general title Agricultural machinery Sprayers - 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 recen
19、t years, several countries have developed systems for inspection of field crop sprayers in use. Developments in this direction have 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:
20、? 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 can be complimented by national regulations); ? less potential risk of environmental contamination by crop protection products
21、; ? good control of the pest with the minimum possible input of crop protection product. 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 step after having standar
22、dized 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 countries are bound to implemen
23、t 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.

This i
25、s 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 management of the inspection, w
26、hich 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 produced before EN 907 and EN 12761 came into force do not fulfi
27、l 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 of the sprayer in respect of safety hazards for the test operator
28、, 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, and can be complimented by national regulations. 2

These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revision
30、s 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 gauges Part 1: Bourdon tube pressure gauges Dimensions, me
31、trology, requirements and testing. ISO 5682-2:1997, Equipment for crop protection Spraying equipment Part 2: Test methods for hydraulic sprayers. 3 Inspection The compliance with the requirements defined in the following clauses shall be checked by inspection, function tests and measurements. NOTESo
32、me 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 national regulatory conditions and health and safety require
33、ments should be followed.

34、 connection (PIC) shall be fitted and in good condition: ? the different parts of the shaft, the universal joints and locking systems shall not show any mark of excessive wear and shall operate correctly ; ? the function of the guard shall be obvious and the guard shall not show any wear marks, hole
35、s, deformations or tears; ? the restraining device that prevents the rotation of the power take-off drive shaft guard shall be present and shall work reliably. The protective devices and any moving or rotating power transmission parts shall not be affected in their function. Method of verification:
36、inspection and function test. 4.1.2A device for supporting the PTO drive shaft when not in use shall be present and in good condition. The chain or device used for restraining the PTO shaft guard shall not be acceptable for this purpose. The guard of the power input connection (PIC) shall be fitted
37、and in good condition. 4.2 Pump 4.2.1The pump 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.
