[中文适用范围]： 本文件规定了便携式、手持式、电动割灌机和割草机的设计和构造的安全要求及其验证措施，这些割灌机和割草机配有背负式内燃机动力源，并在动力源和切割附件之间进行机械动力传输（以下简称“机器”）。规定了消除或减少使用这些机器所产生的危险的方法，以及制造商应提供的安全工作规范信息类型。本文件与 ISO 11806-1:2021 的相关条款（见 4.1）一起，处理了这些机器在按预期使用和制造商可合理预见的误用条件下使用时的所有重大危险、危险情况和危险事件，但背负式动力装置引起的全身振动除外。注 1：在发布时，尚未提供用于测量背负式动力装置引起的全身振动的标准化测试程序。注 2 有关重大危险的列表，请参阅附件 A 以及 ISO 11806-1:2021 附件 A。本文件适用于其发布日期后生产的便携式、手持式、电动割草机和割草机。本文件不适用于配备由多个部件组成的金属切割附件（如枢转链或连枷刀片）的机器。 [外文原描述]： This document specifies safety requirements, and measures for their verification, for the design and construction of portable, hand-held, powered brush-cutters and grass-trimmers with a backpack-mounted combustion engine power source and mechanical power transmission between the power source and the cutting attachment (hereafter referred to as “machine”). Methods for the elimination or reduction of hazards arising from the use of these machines and the type of information on safe working practices to be provided by the manufacturer are specified. This document, taken together with the relevant clauses of ISO 11806-1:2021 (see 4.1), deals with all significant hazards, hazardous situations and hazardous events, with the exception of whole-body vibration from the backpack power unit, relevant to these machines when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer. NOTE 1 A standardized test procedure for measuring whole-body vibration from the backpack power unit is not available at the time of publication. NOTE 2 See Annex A, together with ISO 11806-1:2021, Annex A, for a list of significant hazards. This document is applicable to portable, hand-held, powered brush-cutters and grass-trimmers manufactured after its date of publication. This document is not applicable to machines equipped with metallic cutting attachments consisting of more than one piece, such as pivoting chains or flail blades.
