What is IEC 60335-2-91?

The International Electrotechnical Commission (IEC) is an international standards organization that specifies safety and performance requirements for electrical equipment. One of the standards it has developed is IEC 60335-2-91. In this article, we will dive deep into the technical details of this standard, exploring its purpose, scope, and key requirements.

Purpose of IEC 60335-2-91

IEC 60335-2-91 specifically focuses on the safety requirements for appliances used in residential kitchens. The standard aims to ensure that these appliances do not pose any electrical or mechanical hazards to users. By setting out clear guidelines and tests, it helps manufacturers produce safer and more reliable products.

Scope and Coverage

This standard covers a wide range of kitchen appliances, including ovens, microwave ovens, stoves, grills, blenders, and food processors. It provides requirements for their electrical safety, earthing, insulation, protection against electric shock, and resistance to water ingress. Additionally, it addresses mechanical risks, such as sharp edges, moving parts, and stability of the appliances.

Key Requirements and Tests

To meet the requirements of IEC 60335-2-91, manufacturers must ensure that their appliances comply with various tests. These tests include measuring insulation resistance, conducting high-voltage tests, testing for protection against electric shock, and assessing the stability and robustness of the appliance. Compliance with these requirements helps prevent accidents and ensures the long-term safety and performance of the appliances.
