What is UL910?

UL910 is a standard established by Underwriters Laboratories (UL) for testing the burn characteristics of materials used in the construction of fire-resistant cables. It outlines specific requirements and criteria for evaluating the fire performance of cables.

Importance of UL910 Certification

Obtaining UL910 certification is crucial for manufacturers of fire-resistant cables. This certification ensures that the cables meet the necessary safety standards and can withstand fire conditions without spreading flames or emitting excessive smoke. UL910 certification is often a requirement in industries where fire safety is of utmost importance, such as aerospace, oil and gas, and transportation.

Testing Procedures

The testing procedures specified by UL910 involve subjecting cable samples to various conditions designed to simulate real-life fire scenarios. These conditions include flame exposure, radiant heat, and smoke generation. The cable is evaluated based on factors such as flame spread, smoke density, and the amount of heat released during combustion.

Compliance Criteria

To achieve UL910 certification, cables must meet specific compliance criteria. The flame spread on the cable's surface is measured against a set limit, ensuring that the fire doesn't propagate along the cable. Smoke density is evaluated to determine the visibility impairment caused by the burning cable. Additionally, the heat release rate is measured to prevent excessive energy release during combustion.
