What is UL 498 Ed 13?

UL 498 Ed 13 is a professional technical standard that sets forth the safety requirements for plugs and receptacles. It is published by Underwriters Laboratories (UL), an independent testing and certification organization.

Background

UL 498 Ed 13 is the latest edition of the standard, which was first introduced in the early 1900s. Over the years, it has undergone several revisions to keep up with advancements in technology and ensure the safety of electrical products.

The standard covers various aspects of plug and receptacle design, construction, and performance. It specifies requirements for materials used, including their flammability properties, mechanical strength, and resistance to environmental factors such as moisture and heat.

Key requirements and tests

UL 498 Ed 13 outlines specific criteria that plugs and receptacles must meet to comply with the standard. These include:

Rated current and voltage: The standard defines different ratings based on the intended use and location of the product.

Contact pins and terminals: There are detailed specifications for the size, shape, and configuration of pins and terminals to ensure proper electrical contact and prevent hazards such as arcing or overheating.

Grounding: Requirements for grounding systems are outlined to minimize the risk of electric shock or fire.

Temperature rise: Tests are conducted to evaluate the temperature rise of plugs and receptacles during normal operation to prevent excessive heating.

Markings and labeling: Products compliant with UL 498 Ed 13 must display appropriate markings and labels indicating certification, ratings, and manufacturer information.

Benefits of compliance

Complying with UL 498 Ed 13 is crucial for manufacturers as it demonstrates their commitment to producing safe and reliable electrical products. Certification by UL provides customers and regulatory authorities with confidence in the product's quality and safety.

Additionally, adhering to the standard helps prevent accidents, injuries, and property damage caused by faulty or substandard plugs and receptacles. It contributes to overall electrical system safety and reduces the risk of electrical fires.

Conclusion

UL 498 Ed 13 is a comprehensive technical standard that sets forth the requirements for plugs and receptacles, ensuring their safety and reliability. Manufacturers should strive to meet these standards to provide consumers with high-quality electrical products that comply with regulatory requirements.
