Safety of hand-held motor-operated electric tools. Part 2: Particular requirements for screwdrivers and impact wrenches

This specification outlines specific safety requirements for electrical hand tools, focusing on rotary tools and impact wrenches. It establishes essential criteria to ensure the protection of users during operation, covering design, construction, and performance aspects unique to these device types. The document addresses critical areas such as mechanical integrity, electrical insulation, and protection against hazards arising from impact forces or rotational stresses. It provides detailed guidance on testing procedures necessary to verify compliance with safety limits. By defining mandatory parameters for components like handles, switches, and guards, it aims to minimize risks associated with misuse or malfunction. The content serves as a technical reference for manufacturers to integrate safety features during production and for regulatory bodies to assess product conformity. It complements general safety standards for handheld equipment by addressing nuances specific to torque-generating and hammering actions. Implementation of these guidelines contributes to a safer working environment across various industries where such tools are commonly employed for assembly, maintenance, or construction tasks.
