What is UL 887

UL 887 is a standard that ensures the safety and performance of electrical cord sets and power supply cords. It is crucial for manufacturers and consumers to understand this standard to ensure the safe usage of electrical products. In this article, we will explore what UL 887 entails and why it is significant in the industry.

The Purpose of UL 887

The Underwriters Laboratories (UL) developed UL 887 to establish safety requirements and performance criteria for cord sets and power supply cords. The standard covers various aspects, including design, construction, materials, and testing procedures. Its primary objective is to minimize potential hazards associated with electrical cords and enhance the overall safety of electrical devices used by consumers and professionals.

Key Requirements of UL 887

To meet the UL 887 standard, cord sets and power supply cords must undergo rigorous testing and verification processes conducted by authorized testing laboratories. Some of the key requirements include:

Conductor Size: The standard specifies the minimum gauge size of conductors used in the cord sets, ensuring adequate current carrying capacity.

Insulation and Jacketing Materials: Specific materials with appropriate thermal and mechanical properties are mandated to protect against fire, electrical shocks, and physical damage.

Markings and Labeling: Cord sets should be clearly marked with relevant information, such as voltage ratings, wire gauges, and warnings, to aid proper usage and identification.

Plugs and Receptacles: UL 887 includes requirements for plug and receptacle configurations, ensuring compatibility, reliability, and proper connection.

Flexing Tests: Cord sets must undergo flexing tests to evaluate their durability and resistance against repeated bending, ensuring reliable performance over time.

The Significance of UL 887

UL 887 certification provides reassurance to manufacturers, retailers, and consumers that cord sets and power supply cords meet stringent safety standards. Compliance with UL 887 ensures that electrical products are manufactured using safe materials, constructed properly, and tested for reliable performance. For consumers, this means increased peace of mind when using electrical devices, knowing that they have met the rigorous requirements necessary to minimize risks.

In addition, UL 887 compliance enhances product quality and reliability, contributing to customer satisfaction and trust. Manufacturers who adhere to this standard demonstrate their commitment to delivering safe and dependable electrical products.
