What is IEC 60335-2-146:2020?

IEC 60335-2-146:2020 is a technical standard developed by the International Electrotechnical Commission (IEC) that specifically deals with the safety requirements for electric water heaters. This standard provides guidelines and regulations to ensure the safe operation of electric water heaters, protecting both users and the environment.

Why is IEC 60335-2-146:2020 important?

Electric water heaters are commonly used in households, commercial buildings, and industrial settings. These devices heat water for various purposes, such as bathing, cleaning, and heating. It is essential to have strict safety standards in place to avoid accidents, minimize potential hazards, and promote product reliability. IEC 60335-2-146:2020 ensures that electric water heaters meet specific safety requirements, reducing the risk of electrical shock, fire incidents, and other potential dangers.

Main requirements of IEC 60335-2-146:2020

IEC 60335-2-146:2020 outlines several important safety requirements that electric water heaters must adhere to. Some of the main requirements include:

Protection against electric shock: The standard sets guidelines for insulation, grounding, and protection against short circuits to prevent users from coming into contact with live components.

Temperature controls: The standard specifies temperature limits to ensure that hot water is produced at safe and controlled levels, preventing scalding accidents.

Water temperature regulation: Electric water heaters must be equipped with devices to limit water temperature and prevent it from exceeding preset limits.

Overpressure protection: The standard mandates safety mechanisms to prevent excessive pressure buildup within the water heater, reducing the risk of explosions and other related hazards.

Protection against abnormal operation: IEC 60335-2-146:2020 includes requirements for protection against abnormal operation conditions such as loss of water supply or overheating.

Compliance and certification

To ensure compliance with IEC 60335-2-146:2020, manufacturers of electric water heaters must subject their products to rigorous testing and evaluation. Only after meeting all the standard's specified requirements can a water heater be certified to confirm its safety and reliability. Compliance with this standard provides reassurance to consumers and regulatory bodies that the electric water heater meets the necessary safety benchmarks.
