标准范围

本文件规定了带背包动力装置（以下简称“机器”）的便携式、手持式、杆装动力修剪机的设计和施工的安全要求和验证措施。这些机器使用动力传动轴将动力传输至切割附件，切割附件由锯链和导杆、往复式锯片或最大外径为205？mm的单件圆形锯片组成。规定了消除或减少因使用这些机器而产生的危险的方法，以及制造商提供的有关安全工作实践的信息类型。本文件与ISO？11680-1:2021的相关章节一起，涉及所有重大危险、危险情况或危险事件，但因接触架空电线而触电的情况除外（本说明中包含的警告和建议除外）以及整个事故-背包动力装置产生的身体振动，当这些机器按预期使用时，以及在制造商可合理预见的误用情况下，与这些机器相关。注？1？在出版之日，没有测量背包动力装置全身振动的标准化测试程序。注2:重大危险清单见附件A。本文件适用于出版日期后制造的便携式、手持式、杆装式动力修剪机，带背包动力装置。

This document specifies safety requirements and measures for their verification for the design and construction of portable, hand-held, pole-mounted powered pruners with a backpack power unit (hereafter referred to as “machine”). These machines use a power transmission shaft to transmit power to a cutting attachment consisting of a combination of saw-chain and guide bar, a reciprocating saw blade or a single-piece circular saw blade with a 205 mm maximum outside diameter. 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, together with the relevant sections of ISO 11680-1:2021, deals with all significant hazards, hazardous situations or hazardous events, with the exception of electric shock from contact with overhead electric lines (apart from warnings and advices for inclusion in the instructions) and 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 date of publication.NOTE 2   See Annex A for a list of significant hazards.This document is applicable to portable, hand-held, pole-mounted powered pruners with backpack power unit manufactured after its date of publication.
