[中文适用范围]： 国际电工委员会（IEC）62841-4-8:2025版的扩展版本（EXV）包含该国际标准及其扩展内容。此官方IEC标准的扩展版本仅以英文提供，为用户提供全面的标准内容。IEC 62841-4-8:2025 EXV涵盖了引用到IEC 62841-1:2014的所有相关内容。 本文件规定了手供料碎屑机/切片机（配备内置电动机，可带或不带真空辅助收集系统）的设计和制造中的安全要求及其验证方法。这些设备旨在将有机材料破碎成较小颗粒，并由站在地面上的操作人员在固定位置使用。 本文件适用于进料开口或进料安全开口的总面积不超过250毫米×250毫米的碎屑机/切片机。注：101 对于250毫米×250毫米正方形测量要求，请参见19.101.1。本文件中将碎屑机/切片机统称为机器（们）。 本文件不涵盖以下内容的安全要求： - 由内燃机驱动的设备； - 外部电源驱动的设备； - 具有动力输出装置，用于散播物料或装载车辆的设备； - 配备机械进料装置或附件的设备； - 用于林业、农业、园艺和景观美化领域的木屑切片机。 本文件应与IEC 62841‑1:2014一起使用。本文件补充或修改了IEC 62841-1的相关条款，以将其转换为适用于碎屑机/切片机的国际电工委员会标准：特殊要求。 [外文原描述]： IEC 62841-4-8:2025 EXV contains both the international standard and its extended version (EXV). This extended version of the official IEC Standard is available in English only and provides the user with a comprehensive content of the Standard. IEC 62841-4-8:2025 EXV includes the content of the references made to IEC 62841-1:2014. IEC 62841-4-8:2025 specifies safety requirements and their verification for the design and construction of hand fed, shredders/chippers with an integral electric motor, with or without vacuum assisted collection, which are designed to reduce organic material to smaller pieces and are used in a stationary position by an operator standing on the ground. This document applies to shredders/chippers with feed intake openings or feed safety openings that in total will fit into a square of 250 mm x 250 mm. NOTE 101 The requirements for the measurement of the square of 250 mm x 250 mm are specified in 19.101.1. In this document, shredders/chippers are referred to collectively as machine(s). This document does not cover requirements for - machines powered by combustion engines; or - machines driven by an external power source; or - machines with powered discharge intended to broadcast material or load vehicles; or - machines with mechanically powered feed intake or attachments; or - wood chippers for forestry, agriculture, horticulture and landscaping. This document is to be used in conjunction with IEC 62841‑1:2014. This document supplements or modifies the corresponding clauses in IEC 62841-1, so as to convert it into the IEC Standard: Particular requirements for shredders/chippers.
