Nores:

1) Rope size number is the nominal circumference of the rope in inches. AIr circumferences and diameters are

approximate, as derermined by common rope industry practices.

2) British and Japanese Standards are for rope lested withoul splices. Sphced strenglh is approximately 90% of

unspliced strength. New ISO and DIN Standards are essentially equivalent 10 British Standard.
