EN 13790-2:2003 (E)3ForewordThis document (EN 13790-2:2003) has been prepared by Technical Committee CEN/TC 144 “Tractors andmachinery 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 identicaltext or by endorsement, at the latest by November 2003, and conflicting national standards shall be withdrawnat 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 Part 2: Air-assisted sprayers for bush and tree cropsAnnexes A and B are informative.During recent years, several countries have developed systems for inspection of air-assisted sprayers forbush and tree crops in use. Developments in this direction have been stimulated by public concern aboutrisks, 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 workequipment at work directive 95/63/CE, amending directive 89/655/CEE, and can be complimented bynational 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 importance for the efficiency ofthe 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 therequirements and test methods for sprayers in use. This is a relevant step after having standardized therequirements for new equipment, in respect of safety hazards (see EN 907) and potential risks ofenvironmental contamination (see EN 12761 Parts 1 to 3).According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries 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.SIST EN 13790-2:2004
EN 13790-2:2003 (E)4IntroductionStandardising the requirements and methods for inspection of sprayers in use, takes into consideration notonly the original performance of the spraying equipment, but also its use, care and maintenance. This is thelogical 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 officialor legal specifications are necessary, e.g. on the execution management of the inspection, whichorganizations are authorized to carry out the inspection, time intervals between inspections etc. As thespecifications of this European Standard are based on EN 907 and EN 12761, it may be the case thatsprayers in use which were produced before EN 907 and EN 12761 came into force do not fulfil all thespecifications given in this European Standard.1 ScopeThis 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 sprayer in respect ofsafety hazards for the test operator, the potential risk of environmental contamination and opportunities toachieve good application.NOTEMinimum requirements are given concerning operator safety in the use of work equipment at work directive95/63/CE, amending directive 89/655/CEE, and can be complimented by national regulations.2 Normative referencesThis 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 listedhereafter. For dated references, subsequent amendments to or revisions of any of these publications apply tothis European Standard only when incorporated in it by amendment or revision.

Anyperson performing tests in accordance with this standard should be appropriately trained in the type of work to be carriedout. All national regulatory conditions and health and safety requirements should be followed.SIST EN 13790-2:2004
