What is IEC 60335-2-131:2020?

The IEC 60335-2-131:2020 is an international standard developed by the International Electrotechnical Commission (IEC) that sets forth safety requirements for household and similar electrical appliances. It specifically focuses on appliances that are used for heating, cooking, and processing food.

Safety Requirements for Heating Appliances

The IEC 60335-2-131:2020 standard encompasses a wide range of safety measures to ensure the safe operation of heating appliances. These include requirements related to electrical insulation, protection against electric shock, temperature controls, overvoltage protection, and mechanical strength. The standard also addresses fire risk prevention, such as the use of flame guards and thermal safety switches.

Appliances covered by this standard include electric ovens, stoves, ranges, microwave ovens, portable grills, toasters, and other similar devices commonly found in households.

Protection Against Thermal Hazards

In order to protect users from thermal hazards, the IEC 60335-2-131:2020 standard mandates specific requirements for different components of heating appliances. This includes the use of suitable materials with appropriate melting points, ensuring adequate spacing between hot surfaces and combustible materials, implementing effective thermal insulation, and preventing excessive temperatures in accessible parts.

The standard also addresses safety aspects related to appliances with built-in self-cleaning functions or pyrolytic cleaning systems, ensuring that these features do not pose any risk of fire or other thermal hazards.

Testing and Certification

Manufacturers of heating appliances are required to conduct various tests according to the guidelines specified in IEC 60335-2-131:2020. These tests evaluate the safety performance of the appliances and their compliance with the standard's requirements. The standard provides detailed procedures for conducting these tests, including measurement of surface temperatures, resistance to heat, and verification of protective measures.

Compliance with the IEC 60335-2-131:2020 standard is crucial for manufacturers seeking international market access for their products. Third-party certification bodies conduct audits and tests to ensure that appliances meet the specified safety requirements before they can be sold in various markets around the world.

In conclusion, the IEC 60335-2-131:2020 standard plays a vital role in ensuring the safety of heating appliances used in households. By setting clear guidelines and requirements, it helps manufacturers produce appliances that are free from electrical, thermal, and fire hazards. This standard not only protects consumers but also promotes global harmonization of safety standards in the electrical appliance industry.
