What is UL 694?

UL 694, also known as the Standard for Flexible Cord and Cable, is a safety standard published by Underwriters Laboratories (UL). It specifies the requirements for the construction, performance, testing, and labeling of flexible cords and cables. These cables are widely used in various industries to power electrical equipment and devices.

The Importance of UL 694 Compliance

Complying with UL 694 is crucial for manufacturers and users of flexible cords and cables. The standard ensures that these products meet specific safety and performance criteria, minimizing the risk of electrical hazards such as fires, shock, and overheating. By using UL 694 compliant cables, businesses and individuals can have confidence in the reliability and safety of their electrical systems.

Key Requirements of UL 694

UL 694 sets forth a comprehensive set of guidelines that cover various aspects of flexible cord and cable manufacturing. Some of the key requirements include:

Conductor material and size specifications

Insulation and jacket materials

Temperature ratings and ampacity

Flame resistance and fire protection

Oil resistance and water immersion

Durability and physical strength

The Testing and Certification Process

To ensure compliance, manufacturers must subject their flexible cords and cables to rigorous testing procedures. These tests evaluate factors such as electrical conductivity, insulation integrity, and mechanical strength. Upon successful completion of the testing process, the products can be certified by UL. The UL mark on a cable indicates that it has met all the necessary requirements and has undergone thorough testing to ensure its safety and performance.
