What is UL 566?

UL 566 is a technical standard that relates to a specific type of electrical cord. It sets forth the requirements for flexible cords, which are commonly used in various applications such as appliances and electronic equipment.

Understanding the Purpose of UL 566

The main purpose of UL 566 is to ensure safety and reliability in the use of flexible cords. It specifies the construction and performance tests that these cords must undergo to meet the established safety standards. By adhering to UL 566, manufacturers and consumers can have confidence in the quality and safety of these cords.

Key Requirements of UL 566

UL 566 covers various aspects of flexible cords, including their materials, construction, and markings. Here are some key requirements outlined in this standard:

Conductor Size: The standard specifies the minimum size of conductors, ensuring they are suitable for carrying the required electrical load without overheating.

Jacket Material: The jacket material used in the cord should be resistant to heat, oil, moisture, and other environmental factors that can affect its performance and safety.

Markings: Each cord should be clearly marked with important information, including voltage rating, conductor material, and manufacturer's identification.

Flexibility Testing: The flexibility of the cord is evaluated through specific bending tests to ensure it can withstand normal usage without damage.

Flammability: UL 566 sets requirements for flame resistance, minimizing the risk of fire hazards associated with flexible cords.

Compliance and Certification

Manufacturers must comply with the requirements of UL 566 to ensure their flexible cords are safe and reliable. They can have their products tested and certified by a recognized testing laboratory, such as Underwriters Laboratories (UL), to demonstrate compliance. Consumers should look for the UL mark on the cord or packaging to ensure they are purchasing a product that meets the safety standards set forth by UL 566.

In conclusion, UL 566 is a technical standard that plays a crucial role in ensuring the safety and reliability of flexible cords. By setting forth specific requirements and tests, it helps manufacturers and consumers make informed decisions about the cords they choose to use or purchase. Compliance with UL 566 not only promotes safety but also instills confidence in the quality of these electrical products.
