What is IEC 60335-3-28?

IEC 60335-3-28 is an international standard that specifies safety requirements for household and similar electrical appliances. It is part of the International Electrotechnical Commission (IEC) 60335 series, which covers a wide range of electrical appliances used in domestic and commercial settings.

Scope of IEC 60335-3-28

This specific standard, IEC 60335-3-28, focuses on the requirements for safety of batteries and battery-powered electrical appliances. It applies to both portable and stationary appliances that use primary or secondary batteries as their power source. The standard aims to ensure the safe operation of these appliances and protect users from potential hazards related to batteries or their charging systems.

Key Requirements and Tests

The standard defines several key requirements and tests that manufacturers must comply with when designing and manufacturing battery-powered electrical appliances:

Battery Safety: The standard specifies measures to prevent battery leakage, overheating, explosion, and other potential hazards related to batteries.

Charging Systems: It outlines safety requirements for battery charging systems to prevent overcharging, short circuits, and other malfunctions.

User Protection: IEC 60335-3-28 emphasizes user protection by requiring adequate insulation, protective covers, and proper labeling on appliances.

Environmental Considerations: The standard also addresses environmental aspects, such as the disposal and recycling of batteries, to minimize their impact on the environment.

Compliance and Certification

To ensure compliance with IEC 60335-3-28, manufacturers are required to conduct various tests and assessments. These may include laboratory testing, inspection of production processes, and examination of technical documentation. Once compliance is achieved, manufacturers can obtain relevant certifications or marks to demonstrate their adherence to the standard's safety requirements.

It is important for consumers to look for products that bear these certifications or marks when purchasing battery-powered electrical appliances, as it indicates that the product has undergone rigorous testing and meets the necessary safety standards.
