UL Plenum Cable Flame Test samples must be provided on a reel or spool.
L = length of sample in feet; D = diameter of cable in inches
Plenum Cable Flame Test: L = 900/D (Example: For a 0.50 inch diameter cable 900/0.50 = 1800.00 feet)
where, T= Length of Minor Axis in inches
W= Length of Major Axis in inches
</DIV>
