UL 444 Mandrel Wrap Test
Mandrel Wrap testing was performed on a series of jacketed communications cables per UL444. Communication cables were jacketed with 0.020 inches of various Kynar Flex® grades (final diameter of 0.210 inches). Mandrel sizes used were 2.4 inches (12x cable diameter) and 1.3 inches (6.5x cable diameter) at temperatures ranging from -20°C to -60°C. The results of this work are summerized in the following table.
