标准摘要
[中文适用范围]： IEC 62841-2-21:2017+AMD1:2024 CSV 适用于手持式排水沟清洁器（排水沟清洁器也称为管道清洁器），单相交流或直流工具的额定电压不超过 250 V，三相交流工具的额定电压不超过 480 V。额定输入不超过 3700 W。本标准对电池工具的适用性限值在 K.1 和 L.1 中给出。本标准涉及所有人在正常使用和合理可预见的误用工具过程中遇到的工具危险。可安装在支架或工作台上用作固定工具而无需对工具本身进行任何改动的手持式电动工具属于本标准的范围，这种手持式工具和支架的组合被视为可移动工具，因此属于相关第 3 部分的内容。本标准不适用于可移动式排水沟清洁器。本标准不适用于使用实心棒清洁排水沟的机器。本第 2-21 部分应与 IEC 62841-1:2014 第一版配合使用。请国家委员会注意，在新的、修订的或修订的 IEC 出版物发布后，设备制造商和测试组织可能需要一段过渡期，以便根据新要求制造产品并装备自己进行新的或修订的测试。委员会建议，本出版物的内容应在发布之日起 36 个月内全国实施。 [外文原描述]： IEC 62841-2-21:2017+AMD1:2024 CSV applies to hand-held drain cleaners (drain cleaners are also known as pipe cleaners) the rated voltage is not more than 250 V for single-phase a.c. or d.c. tools, and 480 V for three-phase a.c. tools. The rated input is not more than 3 700 W. The limits for the applicability of this standard for battery tools are given in K.1 and L.1. This standard deals with the hazards presented by tools which are encountered by all persons in the normal use and reasonably foreseeable misuse of the tools. Hand-held electric tools, which can be mounted on a support or working stand for use as fixed tools without any alteration of the tool itself, are within the scope of this standard and such combination of a hand-held tool and a support is considered to be a transportable tool and thus covered by the relevant Part 3. This standard does not apply to transportable drain cleaners. This standard does not apply to machines that use a solid rod to clean drains. This Part 2-21 is to be used in conjunction with the first edition of IEC 62841-1:2014. The attention of National Committees is drawn to the fact that equipment manufacturers and testing organizations may need a transitional period following publication of a new, amended or revised IEC publication in which to make products in accordance with the new requirements and to equip themselves for conducting new or revised tests. It is the recommendation of the committee that the content of this publication be adopted for implementation nationally not earlier than 36 months from the date of publication.
