What is UL 498:2004?

UL 498:2004 is a set of safety standards developed by Underwriters Laboratories (UL), an independent product safety certification organization. This standard specifically pertains to attachment plugs and receptacles, also known as power cords and sockets. It establishes the requirements for design, construction, and performance of these electrical devices.

Design and Construction Requirements

To adhere to UL 498:2004, attachment plugs and receptacles must meet strict design and construction requirements. These include aspects such as materials used, dimensions, markings, and accessibility of internal parts. The standard sets guidelines for the proper sizing and shaping of live parts, ensuring safe and efficient electrical connections.

Performance Testing

Another crucial aspect of UL 498:2004 is performance testing. Manufacturers need to subject their attachment plugs and receptacles to various tests to ensure compliance with the standard. These tests evaluate factors such as mechanical strength, electrical conductivity, resistance to heat, impact resistance, resistance to chemicals, and overall durability and reliability.

Benefits of UL 498:2004 Compliance

Compliance with UL 498:2004 provides several benefits. Firstly, it assures consumers and authorities that the attachment plugs and receptacles they are using meet strict safety standards. This instills confidence in the safety and reliability of the products. Secondly, complying with the standard minimizes the risk of electrical accidents, such as electric shock or fires, resulting from faulty plugs or receptacles. Lastly, UL 498:2004 compliance enhances marketability and competitiveness for manufacturers, as it demonstrates their commitment to producing high-quality and safe electrical products.
