What is IEC 60335-2-104:2020?


In the world of electrical appliances, safety and reliability are paramount. The International Electrotechnical Commission (IEC) governs the standards for electrical safety worldwide. One such standard is the IEC 60335-2-104:2020 that specifically focuses on the safety requirements for appliances used in professional kitchens, such as commercial ovens, grills, and ranges.

of IEC 60335-2-104:2020

The IEC 60335-2-104:2020 standard is designed to ensure the safety of professional kitchen appliances, both for the operators and the end-users. It covers a wide range of aspects, including electrical safety, mechanical safety, thermal protection, and even protection against hazardous substances.

Electrical Safety

This section of the standard addresses various electrical safety concerns, such as insulation requirements, earthing, and protective measures against electric shocks. It also sets guidelines for the safe design and installation of heating elements, control systems, and power supplies in professional kitchen appliances.

Mechanical Safety

Mechanical safety is another critical aspect covered by IEC 60335-2-104:2020. It specifies requirements for the construction of appliance exteriors and components to prevent injury or damage caused by moving parts or excessive forces. Door mechanisms, hinges, and locks are carefully examined to ensure they meet the necessary safety standards.

Thermal Protection

Professional kitchen appliances generate high levels of heat during operation, which can be a potential hazard. The standard mandates the inclusion of appropriate thermal protection mechanisms to prevent overheating and reduce the risk of fire. It also sets limits on surface temperatures to avoid burns to operators who come into contact with the appliance.

Protection against Hazardous Substances

Many appliances used in professional kitchens employ chemicals or generate harmful substances, such as fumes or particles. IEC 60335-2-104:2020 sets clear guidelines for minimizing the release of hazardous materials, ensuring proper ventilation systems are in place, and providing adequate warning labels to prevent health risks.


The IEC 60335-2-104:2020 standard plays a crucial role in ensuring the safety and reliability of professional kitchen appliances. By adhering to its guidelines, manufacturers can create appliances that not only perform efficiently but also minimize risks to both operators and end-users. As consumers, we can have peace of mind knowing that the appliances we use in commercial kitchens are developed in accordance with these rigorous safety standards.
