What is the difference between UL 1569 and 1007?

UL 1569 and UL 1007 are both standards developed by Underwriters Laboratories (UL) for electrical wires and cables. These standards help ensure the safety and reliability of electrical products by providing guidelines for their construction and performance. While both UL 1569 and 1007 address similar aspects related to wire and cable specifications, they do have some differences. In this article, we will explore the variances between these two UL standards to get a better understanding of their applications and implications.

UL 1569: An Overview.

UL 1569 is a standard specifically developed for appliance wiring materials. It sets out the requirements for wires and cables used in internal wiring of appliances, switchboards, and other electrical installations. This standard covers both single-conductor and multi-conductor cables with insulation and jackets made of various materials like PVC, cross-linked polyethylene, and rubber. UL 1569 provides guidelines for voltage ratings, conductor sizes, insulation thickness, conductor stranding, flammability, and other aspects to ensure the safe operation and protection against electrical hazards.

UL 1007: An Overview.

On the other hand, UL 1007 is a standard that specifies the requirements for wire used as internal wiring in electronic equipment. It is intended for use in applications where the wire will not be exposed to mechanical abuse or extreme temperatures but still requires adequate electrical insulation. UL 1007 covers single-conductor solid or stranded wires with PVC insulation and is commonly used in low-voltage applications such as internal connections in computers, televisions, and other electronic devices. This standard also outlines the ratings, sizes, and other criteria necessary for a wire to meet the UL 1007 certification.

Voltage Ratings.

One notable difference between UL 1569 and 1007 is the voltage ratings they specify. UL 1569 covers wires and cables with voltage ratings ranging from 30 volts to 600 volts, making it suitable for a wide range of applications where higher voltage requirements are necessary. On the other hand, UL 1007 is limited to lower voltage applications and specifies ratings ranging from 30 volts to 300 volts.

Insulation and Sizes.

Another notable difference lies in the materials and sizes of wires covered by these standards. UL 1569 covers a broader range of insulation materials such as PVC, rubber, and cross-linked polyethylene, while UL 1007 is limited to PVC insulation. Additionally, UL 1007 is commonly available in smaller wire sizes, typically ranging from 30 AWG to 10 AWG, whereas UL 1569 covers a wider range of sizes, from smaller gauge wires to larger ones necessary for higher voltage applications.

Flammability Requirements.

Both UL 1569 and 1007 address flammability requirements to ensure the safety and fire resistance of the wires and cables. However, the specifications for flammability differ between the two standards. UL 1569 generally requires a higher flame retardant rating compared to what is required by UL 1007. This distinction is due to the varying applications and potential risks associated with the use of wires and cables in different environments.

In conclusion, UL 1569 and UL 1007 are both important standards that dictate the requirements for electrical wires and cables. While they share similar goals of ensuring safety and reliability, UL 1569 focuses on appliance wiring materials, covers a broader range of voltages, insulation materials, and sizes, while UL 1007 is more specific to internal wiring in electronic equipment and applies to lower voltage applications. Understanding these differences is crucial for selecting the appropriate wire or cable for specific applications to meet the necessary safety and performance requirements.
