ISO 16119-4:2014规定了3.1和3.2中定义的固定式和半移动式喷雾器的设计和性能要求及其验证方法，以最大限度地降低使用过程中环境污染的潜在风险，包括制造商可预见的误用。 这种类型的喷洒系统通常是单独元件（主罐、泵和喷洒装置）的组合，可在固定装置（固定式喷洒器）或移动部件（半移动式喷洒器）中组装。 ISO 16119-4:2014不适用于空间/空间处理的应用设备。 ISO 16119-4:2014旨在与ISO 16119？1一起使用，该标准给出了ISO 16119涵盖的所有喷雾器类型的通用要求。当ISO 16119-4:2014的要求与ISO 16119-1中的要求不同时，ISO 16119的要求- 对于ISO 16119-4:2014范围内的机器，4:2014优先于ISO 16119-1的要求。ISO 16119-4:2014未涵盖安全方面（见ISO 4254-6）。 ISO 16119-4:2014不适用于发布日期之前制造的喷雾器。

ISO 16119-4:2014 specifies requirements and the means for their verification for the design and performance of fixed and semi-mobile sprayers, as defined in 3.1 and 3.2, with regard to minimizing the potential risk of environmental contamination during use, including misuse foreseeable by the manufacturer. This type of spraying system is generally a combination of separate elements (main tank, pump and application unit) that can be assembled in fixed installations (fixed sprayers) or with moving parts (semi-mobile sprayers). ISO 16119-4:2014 does not apply to application equipment for space/spatial treatments. ISO 16119-4:2014 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 ISO 16119-4:2014 are different from those stated in ISO 16119？1, the requirements of ISO 16119-4:2014 take precedence over the requirements of ISO 16119？1 for machines within the scope of ISO 16119-4:2014. ISO 16119-4:2014 does not cover safety aspects (see ISO 4254？6). ISO 16119-4:2014 is not applicable to sprayers manufactured before the date of its publication.
