本文件将与ISO 4254-1一起使用，规定了制造商投放市场并仅为单个操作员设计的用于植保产品（PPP）和液体肥料施用的安装式、半安装式、牵引式和自行式农业喷雾器的设计和施工的安全要求及其验证。此外，它还规定了制造商提供的安全工作实践（包括剩余风险）信息的类型。 当本文件的要求与ISO 4254-1中规定的要求不同时，本文件的要求优先于ISO 4254-1中针对根据本文件规定设计和制造的机器的要求。 本文件与ISO 4254-1一起论述了喷雾器和液体肥料分配器按预期使用时，以及在制造商可预见的条件下（见附录A）发生的重大危险、危险情况和事件，但以下情况引起的危险除外: -喷洒时保护驾驶员免受喷洒（见前言）； -自动高度调节系统； -环境，而非噪音； -除防护装置和障碍物的强度要求外，用于动力传输的活动部件。 本文件不适用于本文件发布日期之前制造的喷雾器和液体肥料分配器。

This document, to be used together with ISO 4254-1, specifies the safety requirements and their verification for the design and construction of mounted, semi-mounted, trailed and self-propelled agricultural sprayers for use with plant protection products (PPP) and liquid fertilizer application, as placed on the market by the manufacturer and designed for a single operator only. In addition, it specifies the type of information on safe working practices (including residual risks) to be provided by the manufacturer. When requirements of this document are different from those which are stated in ISO 4254-1, the requirements of this document take precedence over the requirements of ISO 4254-1 for machines that have been designed and built according to the provisions of this document. This document, taken together with ISO 4254-1, deals with significant hazards, hazardous situations and events relevant to sprayers and liquid fertilizer distributors when they are used as intended and under the conditions foreseeable by the manufacturer (see Annex A), excepting the hazards arising from: — protection of the driver against spray when spraying (see Foreword); — automatically actuated height adjustment systems; — the environment, other than noise; — moving parts for power transmission except strength requirements for guards and barriers. This document is not applicable to sprayers and liquid fertilizer distributors which are manufactured before the date of publication of this document.
