Verification Method
The test fixture simulates installation frictions generated by pulling the cable through metallic studs in commercial or residential structures. There are a total of 4 vertical metallic studs linearly spaced 17 inches apart with prefabricated cutouts. To promote continual sample to stud contact, the studs have a 20° rotational offset along the vertical axis. Upon exiting the 4th stud, the sample is pulled at an approximate 66° angle of declination around a 12 in pully that effectively executes a 180° change in direction. A compression load sensor is attached to the axis of the pulley and measures the force the cable tension exerts upon the surface of the pulley’s channel. Force measurements are taken every second as 21 +/- 1 ft of the cable under test is pulled through the vertical studs at a rate no greater than 0.60 ft/sec. The cable is pulled four times generating a grand total of 140 force measurements (35 data points per run x 4 runs). The average pull force is the average of all force measurements in the four-run set.
What is UL Verification?
UL Verification is an objective, science-based assessment that confirms the accuracy of marketing claims. Our independent assessment process scrutinizes the validity of specific advertising or promotional statements, giving you a way to separate verified fact from fiction.
