What is UL 60335-2-145?

UL 60335-2-145 is a safety standard defined by Underwriters Laboratories (UL) for household and similar electrical appliances. This standard specifically covers the safety requirements for portable transformers, power supplies, battery chargers, and similar products that are designed for household use.

The Purpose of UL 60335-2-145

The main purpose of UL 60335-2-145 is to ensure the safety of consumers when using household electrical appliances. It sets forth specific guidelines for manufacturers to follow in order to prevent potential hazards such as electric shock, fire, or mechanical injuries.

To comply with this standard, manufacturers must design and produce their products in a way that minimizes risks associated with electrical components, wiring, insulation, temperature rise, and other potential dangers.

The Key Requirements of UL 60335-2-145

UL 60335-2-145 specifies various requirements that manufacturers must meet in order to achieve compliance. Some of the key requirements include:

Protection against electric shock: Appliances must be designed to prevent direct or indirect contact with live electrical parts.

Protection against thermal and mechanical hazards: Products should not cause any harm due to excessive heat, abnormal functioning, or moving parts.

Insulation and dielectric strength: Appliances should have appropriate insulation and withstand specified dielectric strength tests to minimize the risk of electric shock.

Wiring and terminals: Wiring connections and terminals must be secure and properly installed to avoid electrical failures.

Overcurrent and temperature protection: Adequate measures should be taken to protect against overcurrent and excessive temperature rise, which may lead to fire hazards.

Compliance and Certification

Manufacturers must ensure that their appliances meet the requirements outlined in UL 60335-2-145 by conducting appropriate tests and evaluations. Once compliance is achieved, they are eligible for UL certification, indicating that their products meet the safety standards set forth by UL.

Consumers can look for the UL mark on electrical appliances to ensure they have been certified and deemed safe for household use.

Overall, UL 60335-2-145 plays a crucial role in safeguarding consumers by setting safety standards for household electrical appliances. Manufacturers must adhere to these guidelines to provide products that minimize potential risks and ensure consumer safety.
