What is UL 887 ?

UL 887 is a widely recognized standard that aims to establish safety requirements and performance criteria for electrical cord sets and power supply cords. It is developed and published by Underwriters Laboratories (UL), a global organization that specializes in testing and certification.

UL 887 covers various aspects of electrical cord sets and power supply cords, 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

UL 887 has several key requirements that manufacturers and consumers must comply with to ensure the safety and performance of electrical products. These requirements include:

Electrical Safety: The standard covers various aspects of electrical safety, such as insulation, labeling, and marking requirements.

Electrical Conductivity: The standard specifies the minimum electrical conductivity of the cord sets and power supply cords.

Voltage: The standard defines the maximum voltage that can be used in the electrical cords and power supply cords.

Current: The standard specifies the maximum current that can be passed through the electrical cords and power supply cords.

Temperature: The standard sets guidelines for the temperature that electrical cords and power supply cords can operate at.

Strain: The standard tests the strength and flexibility of the electrical cords and power supply cords under various conditions.

Compliance with UL 887

Compliance with UL 887 is mandatory for manufacturers of electrical cord sets and power supply cords. The standard is widely recognized in the industry, and non-compliance with its requirements can result in legal consequences.
