This part of ISO 16119 specifies requirements and the means for their verification for the design and performance of sprayers for bush and tree crops, as defined in 3.1, and similar crops, with regard to minimizing the potential risk of environmental contamination during use, including misuse foreseeable by the manufacturer. It is not applicable to human-mounted sprayers for bushes or trees. It is intended to be used with ISO 16119-1, which gives general requirements common to all the sprayer types covered by ISO 16119. When requirements of this part of ISO 16119 are different from those which are stated in ISO 16119-1, the requirements of this part of ISO 16119 take precedence over the requirements of ISO 16119-1 for machines within the scope of this part of ISO 16119. This part of ISO 16119 does not cover safety aspects (see ISO 4254-6). This part of ISO 16119 is not applicable to sprayers manufactured before the date of its publication.
