Hereinafter referred to as "tools".
The rated voltage of AC single-phase or DC tools shall not exceed 250V, and the rated voltage of AC three-phase tools shall not exceed 440V. The maximum rated input power shall not exceed 3700W.
This part pertains to the hazards caused by tools when people operate them normally and use them in a reasonably foreseeable manner.
Tools with electric heating elements are within the scope of this part. The requirements for these heating elements are specified in the relevant parts of GB 4706.
For tools that are not isolated from the power grid and whose basic insulation is not designed for the rated voltage of the tool, the requirements are specified in Appendix B. For tools driven by electric motors or electromagnets powered by rechargeable batteries and battery packs used for these tools, the requirements are specified in Appendix K. For such tools that can be operated and/or charged directly on mains or non-isolated power sources, the requirements are specified in Appendix L.
