CRBL = Calculated Rope Breaking Load which takes into consideration a spinning loss coefficient = 0.85.
CSBL = Calculated Sling Breaking Load which takes into consideration a splicing coefficient = 0.75 for hand splicing.
Minimum safety factor = 2.25 according to IMCA M179/PM20.
Where applicable, sling strength has been computed using a tensile grade of 1960/EIPS wire rope.
Sling strength is calculated according to ISO 2408:2004 and/or EN 12385-4: 2002, depending upon
component wire rope size in accordance with IMCA M179-2005.
