手持式电动操作, 便携式工具以及草坪和园艺机械. 安全性. 第1部分: 一般要求

[中文适用范围]： 本标准适用于电动或磁力驱动的：- 手持工具（IEC 62841-2）；- 可运输工具（IEC 62841-3）；- 园林机械（IEC 62841-4）。上述类别统称为“工具”或“机器”。额定电压单相交流或直流工具不超过250 V，三相交流工具不超过480 V。额定输入功率不超过3700 W。电池工具的适用限制见K.1和L.1。本标准处理工具在正常使用和合理可预见的误用中给所有人员带来的危害。带有电加热元件的工具包含在本标准范围内。未与电源隔离且基本绝缘未按工具额定电压设计的电机要求见附录B。由可充电电池供电的电动或磁力驱动工具及其电池组的要求见附录K。此类工具也可直接从电网或非隔离源运行和/或充电的要求见附录L。可安装在支架或工作台上作为固定工具使用的电动手持工具（无需对工具本身进行任何更改）在本标准范围内，此类手持工具与支架的组合被视为可运输工具，因此受第3部分的相关要求覆盖。本标准不适用于：- intended用于存在爆炸性气氛（粉尘、蒸汽或气体）的工具；- 用于准备和加工食品的工具；- 医疗用途的工具；- intended用于化妆品或药品接触的工具；- 加热工具；- 电动家用和类似电器；- 工业机床用电设备；- 用于模型制作的小型低压变压器供电台式工具，例如制造无线电控制模型飞机或汽车等。 [外文原描述]： IEC 62841-1:2014 deals with the safety of electric motor-operated or magnetically driven: - hand-held tools (IEC 62841-2); - transportable tools (IEC 62841-3); - lawn and garden machinery (IEC 62841-4). The above listed categories are hereinafter referred to as "tools" or "machines". 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. Tools with electric heating elements are within the scope of this standard. 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 is scheduled to cancel and replace the fourth edition of IEC 60745-1, published in 2006, the first edition of IEC 61029-1, published in 1990, and the fifth edition of IEC 60335-1, published in 2010, only with respect to requirements concerning lawn and garden machinery. The latter publications remain valid until they are withdrawn. This standard constitutes a technical revision. This edition includes the following significant technical changes with respect to the fourth edition of IEC 60745-1: - requirements in various clauses introduced or modified in order to include the requirements for transportable tools and lawn and garden machinery (formerly covered by IEC 61029-1 and IEC 60335-1); - leakage current test and electric strength test moved from former Clauses 13 and 15 to Annexes C and D; - former Clauses 29, 30 and 31 renumbered to become Clauses 6, 13 and 15; - requirements for electronic safety critical functions added to Clause 18; - requirements for switches revised and moved from Annex I to Clause 23; - clarifications in respect to soft materials (elastomers) added to Clauses 9, 19 and 13; - test finger in Figure 1 of IEC 60745-1 and test probe in Figure 2 of IEC 60745-1 replaced by references to basic IEC standards; - requirements for Li-Ion battery systems added to Annexes K and L and Annex M was removed.
