Noles:
- Rope size number is the nomInal circumference of the rope in inches. All circumferences and diameters are
approximate. as determined by common rope industry practices. - British and Japanese Standards are for rope tested without splices. Spliced strength is appro.ximately 90%
01 unspliced strength, New ISO and DIN Standards are essentially equivalent to British Slandard.
