Scope
This part of GB 3883 involves electric motor or electromagnet driven:
- Handheld electric tools (Part 2);
- Portable electric tools (Part 3);
- Garden tools (Part 4) Hereinafter referred to as "tools" The rated voltage of AC single-phase or DC tools shall not exceed 250 V, and the rated voltage of AC three-phase tools shall not exceed 440 V. The maximum rated input power does not exceed 3700 w
This section covers the hazards caused by tools that people encounter during normal operation and reasonably foreseeable use of tools
Tools for electric heating elements are within the scope of this section. The requirements for these heating elements are specified in the relevant parts of GB4706 For motors that are not isolated from the power grid and whose basic insulation is not designed according to the rated voltage of the tool, the requirements are specified in Appendix B. The requirements for tools driven by electric motors or electromagnets powered by rechargeable batteries, as well as battery packs used for these tools, are specified in Appendix K. The requirements for such tools that can be directly connected to the mains or non isolated power supply for operation and/or charging are specified in Appendix L Handheld electric tools that can be installed on a bracket or workbench as fixed tools without any modification to the tool itself belong to the scope of this part and are specified in Part 3
