What is IEC 60335-2-31?

The international standard IEC 60335-2-31, also known as IEC 60335-2-31: Household and similar electrical appliances - Safety - Part 2-31: Particular requirements for range hoods and other cooking fume extractors, outlines the safety requirements for range hoods and similar appliances. It is an essential document for manufacturers, regulators, and consumers to ensure the safe use of these appliances.

Scope and coverage

IEC 60335-2-31 covers a wide range of household and similar appliances used in kitchens, such as range hoods, cooker hoods, and other fume extractors designed to remove grease, odors, and smoke generated during cooking. These appliances are crucial for maintaining a clean and healthy environment in kitchen spaces.

This standard sets forth specific guidelines and safety measures related to mechanical construction, electrical insulation, protective earthing, temperature rise, and other critical parameters that must be adhered to during the manufacturing process.

Safety considerations

One significant aspect addressed by IEC 60335-2-31 is fire safety. Since range hoods and cooking fume extractors deal with heat sources, combustion by-products, and flammable materials, the prevention of fire hazards is of utmost importance.

Another vital safety consideration outlined in the standard is protection against electric shock. Kitchen appliances are typically exposed to water, steam, and damp conditions, so ensuring proper grounding and effective insulation is crucial to prevent accidents and potential electrocution.

Furthermore, IEC 60335-2-31 also covers safety precautions related to motor-driven fans, speed control devices, filters, and lighting systems in range hoods. This ensures the safe performance of these components under various operating conditions, preventing malfunctions and potential hazards.

Compliance and benefits

Manufacturers must comply with IEC 60335-2-31 to ensure that their products meet the required safety standards. Compliance with this standard allows them to obtain certifications like the CE mark, which demonstrates compliance with the relevant European Union directives.

For regulators and governing bodies, IEC 60335-2-31 provides a benchmark for evaluating the safety of range hoods and similar appliances in the market. It helps establish regulations and requirements that manufacturers must meet to ensure consumer safety.

Finally, for consumers, adherence to IEC 60335-2-31 means peace of mind. By purchasing appliances that comply with this standard, they can trust that these products have undergone rigorous testing and adhere to the highest safety standards, reducing the risk of accidents and ensuring the well-being of themselves and their households.
