IEC 60335-2-108:2020 is an international standard that specifies safety requirements for hand-held motor-operated electric tools, such as drills, saws, and screwdrivers. It was published by the International Electrotechnical Commission (IEC) and is applicable to both professional and domestic tools.
Safety Requirements
The standard outlines various safety measures that should be implemented in the design and manufacturing of these tools to ensure user safety. These requirements include:
Protection against electric shock: The tools should be constructed in a way that prevents users from coming into contact with live parts, reducing the risk of electric shock.
Protection against mechanical hazards: The tools should have appropriate guards and shields to protect users from injury caused by moving parts or flying debris.
Temperature rise: Motor-operated tools should not heat up excessively during use, as this could pose a fire hazard or increase the risk of burns.
Safety markings: Tools should be properly labeled with instructions for safe operation and warnings about potential risks.
Testing and Compliance
To ensure compliance with the standard, manufacturers need to subject their tools to various tests, including:
Dielectric strength test: This test checks the electrical insulation of the tool to ensure it can withstand high voltages.
Endurance test: The tool's performance is evaluated by subjecting it to continuous use under specified conditions to assess its durability.
Overload test: Tools are subjected to excessive loads to determine their ability to handle unexpected stress without causing hazards.
Protective conductor resistance test: This measures the resistance of protective conductors, verifying their effectiveness in preventing electric shock.
Benefits and Implications
Compliance with IEC 60335-2-108:2020 benefits both manufacturers and users. By adhering to the safety requirements, manufacturers can ensure that their tools are safe to use and minimize the risk of accidents or injuries. For users, it provides reassurance that the tools they are purchasing meet international safety standards.
The standard also has implications for regulatory authorities and import/export processes. It helps authorities establish guidelines for tool safety regulations and facilitates international trade by providing a common set of safety requirements.
In conclusion, IEC 60335-2-108:2020 plays a crucial role in promoting the safety of hand-held motor-operated electric tools. By defining safety requirements and testing procedures, this international standard ensures that both manufacturers and users prioritize safety in the design, construction, and use of these tools.
