BASED ON THE NOMINAL NUMBER OF WIRES IN EACH STRAND

Classification	Description
6x7	Containing 6 strands that are made up of 3 through 14 wires, of which no more than 9 are outside wires.
6x19	Containing 6 strands that are made up of 15 through 26 wires, of which no more than 12 are outside wires.
6x37	Containing 6 strands that are made up fo 27 through 49 wires, of which no more than 18 are outside wires.
6x91	Containing 6 strands that are made up of 50 through 74 wires, of which no more than 30 are outside wires.
8x19	Containing 8 strands that are made up of 15 through 26 wires, of which no more than 12 are outside wires.
19x7	Containing 19 strands, each strand is made up of 7 wires. It is manufactured by covering an inner rope of 7x7 left lang lay construction with 12 strands in right regular lay. (The rotation-resistant property that characterizes this highly specialized construction is a result of the counter torques developed by the two layers.) When the steel wire core strand is replaced by a fiber core, the description becomes 18x7.

When a center wire is replaced by a strand, it is considered as a single wire, and the rope classification remains unchanged.
