33、ble input of plant protection product.In order to use plant protection products in agricultural production safely, it is necessary 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 s
34、afety hazards (see ISO 4254-6) and potential risks of environmental contamination (see ISO 16119 series).Standardizing the requirements 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. Thi
35、s is a logical link to ensure the continued benefit arising from the supply of new sprayers of good quality.The inspection of 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
36、management of inspections. These include, for example, requirements for the competence of persons carrying out inspections and the frequency of inspections.NOTE National or local regulations may also apply concerning the qualifications and competence of inspectors.

44、 the pump not running and the sprayer parked on a level horizontal surface, a visual inspection for any leakage from the tank, pump and associated pipes shall be carried out.For high capacity tanks, water filling can be reduced to no less than half of the nominal tank volume, provided an additional
45、inspection of the tank is carried out in order to identify any cracks, holes or other damage that can cause leakage.Compliance shall be checked by inspection.4.1.2 Dynamic leaks4.1.2.1 Leak test when not sprayingWith the sprayer running at a pressure which is equal to the maximum obtainable pressure
