Stainless Steel Wire Testing Equipment UL910 Standard Level For Combustion Test

Stainless Steel Wire Testing Equipment UL910 Standard Level For Combustion Test

Scope of application:

It is suitable for the test of cable and cable duct of CMP class. In the experiment, a number of samples were laid on the horizontal airway of the device, and 87.9KW gas Bunsen burner (30, 000BTU/HR) was burned for 20 minutes. Eligibility criteria for the flame shall not extend to 5 feet away from gas Bunsen flame front optical density peak of 0.5, the average density value maximum, 0.15 this CMP cable is usually installed in the ventilation duct or air handling equipment used in air circumfluence pressurization system, was approved by Canada and the United States.

Meet the standard:
