29、of preparing International Standards is normally carried out through ISO technical committees.

37、here are two main reasons for the inspection: less potential risk of environmental contamination by plant protection products; good control of the pest with the minimum possible input of plant protection product.In order to use plant protection products in agricultural production safely, it is neces
38、sary to define the requirements and test methods for sprayers in use. This is a relevant step after having standardized minimum requirements for new sprayers, in respect of safety hazards (see ISO 4254-6) and potential risks of environmental contamination (see ISO 16119 series).Standardising the req
39、uirements and methods for inspection of sprayers in use, takes into consideration not only the original performance of the sprayer, but also its use, care and maintenance. This is a logical link to ensure the continued benefit arising from the supply of new sprayers of good quality.The inspection of
40、 sprayers in use can be a mandatory requirement or adopted on a voluntary basis. In both cases further requirements, outside the scope of this standard, are necessary for the management of inspections. These include, for example, requirements for the competence of persons carrying out inspections an
41、d the frequency of inspections.NOTE National or local regulations may also apply concerning the qualifications and competence of inspectors.vi ISO 2015 All rights reservedBS EN ISO 16122-3:2015Agricultural and forestry machinery Inspection of sprayers in use Part 3: Sprayers for bush and tree crops1
42、 ScopeThis part of ISO 16122, when used together with ISO 16122-1, specifies the requirements and test methods for the inspection of sprayers for bushes and trees, when in use.The requirements relate mainly to the condition of the sprayer with respect to its potential risk for the environment and it
43、s performance to achieve a good application.NOTE Requirements for the protection of inspectors during an inspection are given in ISO 16122-1.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
