What is UL 1347?

UL 1347 is a technical standard that outlines the safety requirements for wire and cable used in internal wiring of electronic devices. This standard, established by Underwriters Laboratories (UL), ensures that the wire and cable meet certain quality and performance standards, thus minimizing the risk of fire hazards and electrical malfunctions.

The Importance of UL 1347

UL 1347 plays a crucial role in ensuring the safety and reliability of electronic devices. By adhering to this standard, manufacturers can guarantee that their products are using wire and cable that have been tested and approved for use in various applications, such as appliances, computers, and automotive systems. Compliance with UL 1347 also helps manufacturers gain consumers' trust by demonstrating their commitment to product safety.

Key Requirements of UL 1347

UL 1347 specifies several important requirements that wire and cable must meet. These requirements include:

Temperature Rating: The wire and cable must be able to withstand the maximum temperature that they will be exposed to during normal operation without degradation or malfunctioning.

Insulation Thickness: The insulation surrounding the wire must have a minimum thickness to prevent electrical leakage and short circuits.

Flame Resistance: The wire and cable should have adequate flame resistance properties to minimize the spread of fire.

Corrosion Resistance: The wire and cable must be resistant to corrosion, ensuring their long-term performance and reliability.

The Certification Process

To obtain UL certification, manufacturers must submit their wire and cable samples to UL for testing and evaluation. UL's experts thoroughly examine the samples and conduct various tests to verify compliance with UL 1347. If the samples pass all the tests, the manufacturer is granted the UL mark, indicating that their wire and cable comply with the standard. The manufacturer can then use this certification to demonstrate the safety and quality of their products.

UL 1347 is an essential standard in the electronics industry as it ensures that wire and cable used in electronic devices meet stringent safety requirements. By following this standard, manufacturers can enhance the reliability of their products and provide consumers with the assurance that their devices are safe to use.
