Manufacture and Tolerances
Strand Construction. The 6x7 classification ropes shall contain six strands that
are made up of 3 through 14 wires, of which no more than 9 are outside wires
fabricated in one operation.* See Table 4-14 and Figure 437.
(text continued on page 571)
*One operation stratuCWhen the king wire of the strand becomes so large (manufacturer's discretion)
that it is considered undesirable, it is allowed to be replaced with a seven-wire strand manufactured
in a separate stranding operation. This does not constitute a twwperation strand.
