What is EN 60335-2-40:2008?

EN 60335-2-40:2008 is a technical standard that refers to the safety of electric heat pumps, air conditioners, and dehumidifiers for household and similar purposes. This standard, developed by the European Committee for Electrotechnical Standardization (CENELEC), outlines specific safety requirements and test methods for these appliances, aiming to ensure the protection of users and minimize potential hazards.

Importance of EN 60335-2-40:2008

Adhering to EN 60335-2-40:2008 is crucial as it helps manufacturers produce safe and reliable appliances. By following this standard, they can assess and mitigate risks related to electrical, mechanical, thermal, and chemical aspects of their products. Compliance with EN 60335-2-40:2008 ensures that these appliances meet the necessary safety criteria and can be used in households without posing harm to occupants or property.

Key Requirements of EN 60335-2-40:2008

EN 60335-2-40:2008 covers various aspects of appliance safety. Some key requirements include:

Protection against electric shock: The standard specifies insulation and earthing requirements to prevent users from electric shocks.

Thermal protection: Appliances must incorporate safeguards to prevent overheating and potential fire hazards.

Mechanical strength: The standard sets guidelines to ensure that appliances are structurally sound and can withstand foreseeable mechanical stresses.

Chemical hazards: EN 60335-2-40:2008 addresses the potential dangers associated with substances used in these appliances, such as refrigerants, ensuring their safe handling and containment.

Ingress protection: The standard defines the level of protection against solid objects and liquid ingress to safeguard users and prevent damage to internal components.

Testing and Certification

To comply with EN 60335-2-40:2008, manufacturers need to subject their appliances to rigorous testing procedures. These tests assess product performance under various conditions outlined in the standard and verify compliance with safety requirements. Once an appliance successfully meets these criteria, it can be certified as compliant, allowing it to carry the appropriate marking and enter the market for household use.

Additionally, regulatory authorities and independent third-party certification bodies may conduct periodic inspections and audits to ensure continued compliance with EN 60335-2-40:2008. This ongoing oversight helps maintain consumer confidence in the safety of these appliances and ensures that manufacturers consistently adhere to the standard's provisions.
