Notes:
1) Rope size number is the nominal circumference of the rope infnches. All circumferences and diameters
are approximate, as determined by common rope industrypract!ces.
2) British
c and Japanese
., Standards are for rope tested without splices.
c Spliced strengthls approximately
' ,
90% of unsplrced strength. New IS0 and DIN Standards are essentially equrvalenttoBrlt(shSta/)dard.
