Overview
IEC 61029-2-4:1993/AMD1:2001 is an essential international standard amendment focusing on the safety of transportable motor-operated electric tools, specifically addressing particular requirements for bench grinders and combined bench grinders. Published by the International Electrotechnical Commission (IEC), this amendment provides updated safety guidelines and technical specifications that manufacturers and users must adhere to for ensuring operational safety and reliability of bench grinders with wheel and brush diameters up to 200 mm and peripheral speeds not exceeding 50 m/s.
This document serves to enhance the safety frameworks for transportable bench grinders-tools widely used for grinding, polishing, and deburring metal or similar materials in various industrial and workshop environments.
Key Topics
Scope and Definitions
- Covers transportable bench grinders and combined bench grinders with specific wheel and brush dimensions and speeds.
- Defines critical terms such as machine spindle, nozzle for dust collection, and combined bench grinder to clarify scope and applicability.
Markings and User Information
- Requirements for clear markings on combined bench grinders, including maximum brush diameter and safety warnings (e.g., prohibiting grinding wheel use on the brush side).
- Comprehensive user handbook guidance to cover safe operation, wheel/brush maintenance, assembly, and transport.
Safety and Mechanical Hazards
- Mandatory guarding systems for grinders, designed to cover the wheels adequately and resist accidental breakage.
- Installation of spark arrestors to limit sparks and ejected particles improving dust management.
- Work rests with downward-only tilt functionality to enhance safe grinding operations.
- Detailed flange dimension specifications for both grinding wheels and brushes to ensure mechanical integrity and prevent accidents.
Protective Equipment
- Clear guidelines for transparent screen installation and dimensions, enabling operators to see the grinding or brush surface while being shielded from particle projections.
- Protection of the free extremity of rotating shafts, particularly on the brush side, to avoid accidental contact in combined bench grinders.
Stability and Fixation
- Requirements for provisions allowing each bench grinder to be securely fixed to a support for stable and safe operation.
Start Prevention and Control
- Safety measures that prevent accidental starting of the tool, verified by a sphere test to ensure start buttons cannot be activated unintentionally.
Applications
IEC 61029-2-4:1993/AMD1:2001 is highly relevant for:
- Manufacturers and designers of bench grinders and combined bench grinders, providing clear safety construction criteria and testing methods.
- Workshop safety managers who enforce and audit compliance to electrical tool safety practices, helping prevent workplace injuries and equipment damage.
- Regulatory bodies and certification agencies that assess and certify motor-operated electric tools for market access and safety.
- Maintenance personnel and operators who benefit from comprehensive user guidelines for safe operation, reducing risks associated with inappropriate tool use.
The standard is applicable across industrial sectors including metalworking, fabrication, automotive, and maintenance, promoting uniform safety levels internationally.
