What is IEC 60335-2-61

IEC 60335-2-61 is an international safety standard that specifically addresses the safety requirements for electric heat pumps, air conditioners, and dehumidifiers. This technical article aims to provide a thorough understanding of the standard, its scope, and the key safety precautions it outlines.

The Scope of IEC 60335-2-61

The standard applies to electric heat pumps, air conditioners, and dehumidifiers used in residential, commercial, and industrial settings. It covers the safety aspects related to their construction, installation, operation, and maintenance. The scope extends to the protection of users, property, and the environment against hazards associated with these appliances.

Safety Requirements Outlined by IEC 60335-2-61

IEC 60335-2-61 specifies various safety measures that manufacturers must adhere to when designing and producing heat pumps, air conditioners, and dehumidifiers. These include:

Protection against electrical hazards, such as short circuits and electric shock;

Insulation requirements to prevent electric shock;

Protection against fire hazards, including flammable refrigerants;

Prevention of mechanical hazards caused by moving parts;

Proper labeling, warnings, and instructions for safe usage;

Evaluation of performance to ensure energy efficiency and environmental sustainability.

Testing and Certification Procedures

To comply with IEC 60335-2-61, manufacturers need to perform various tests on their products to ensure they meet the specified safety requirements. These tests may include:

Electrical insulation tests to verify protection against electric shock;

Overcurrent and short-circuit tests to assess the safety of electrical components;

Temperature rise tests to determine if the appliance operates within safe temperature limits;

Tests for resistance to moisture and dust to ensure the durability of the appliance;

Performance evaluation tests, including energy efficiency and noise levels.

Once the appliances pass all necessary tests and meet the requirements, they can be certified as compliant with IEC 60335-2-61. This certification assures consumers that the products are manufactured with their safety in mind.
