What is UL 817:2007?

UL 817:2007 is a certification standard developed by Underwriters Laboratories (UL), an independent safety science company. This standard specifically addresses the electrical cord sets and power-supply cords used in various electrical appliances, including household and industrial equipment. It sets forth the requirements and guidelines manufacturers must follow to ensure the safe use of these cords, ultimately promoting consumer safety and preventing electrical hazards.

Scope and Requirements

UL 817:2007 covers cord sets and power-supply cords with rated voltages up to 250 volts and currents up to 20 amperes. The standard outlines dimensional requirements, such as cord length and plug design, as well as visual markings and insulation properties necessary for compliance. It also specifies comprehensive testing procedures that manufacturers must undergo to evaluate the performance and safety of their products.

Key Testing Procedures

UL 817:2007 defines various tests to ensure product safety. These tests include, but are not limited to, checks for conductor resistance, dielectric voltage-withstand capability, and polarity. Additionally, the standard evaluates grounding reliability, strain relief effectiveness, and flexing endurance to ensure long-term durability. Conducting these tests is crucial for manufacturers to obtain UL certification and guarantee that their cord sets meet the highest safety standards.

Benefits of UL 817:2007 Compliance

Complying with UL 817:2007 offers several advantages for both manufacturers and consumers. Firstly, it ensures that cord sets and power-supply cords have undergone rigorous testing and meet safety requirements. Secondly, using UL-certified products increases consumer confidence and trust in the brand, which can result in stronger sales and customer loyalty. Moreover, adhering to UL 817:2007 demonstrates a commitment to prioritizing customer safety and providing high-quality, reliable electrical products.
