What is IEC 60335-2-152:2020

IEC 60335-2-152:2020 is an international standard that specifies the safety requirements and test methods for electrically powered appliances used for household and similar purposes. It provides guidelines to ensure the safety of appliances such as electric heating pads, blankets, and medical electrical equipment.

Scope of the Standard

The standard applies to appliances intended for household and similar use, both indoors and outdoors. It covers a wide range of products, including electric heating pads, blankets, and all other electrically powered appliances that generate heat or coolness directly or indirectly.

The standard excludes industrial appliances, portable hand-held tools, medical electrical equipment, and appliances used in hazardous environments.

Safety Requirements

The standard sets out various safety requirements that manufacturers need to comply with when designing and manufacturing these appliances. These requirements cover aspects such as mechanical and electrical safety, temperature limitations, protection against overheating, and protection against electric shock.

For example, the standard specifies the maximum surface temperature for heating elements and limits the allowable contact temperatures for different types of surfaces. It also requires adequate insulation and grounding to prevent electric shock hazards.

Testing Methods

The standard also provides detailed testing methods to evaluate the compliance of appliances with the specified safety requirements. These tests include measuring surface temperatures, conducting dielectric strength tests, and verifying the effectiveness of protective measures.

Manufacturers are required to perform these tests during the development and production stages to ensure that their products meet the safety standards stated by IEC 60335-2-152:2020. Compliance with the standard not only ensures the safety of the consumers but also helps manufacturers gain trust and credibility in the market.
