*NOTE:
Rated breaking strength is the optimum strength, achieved under laboratory conditions, in accordance with prescribed test procedures, on new rope, pulling at a slow steady rate in a straight line. Real life appliations normally involve many other types of forces and factors which will cause the rope to fall at much reduced loads. Accordingly, the safe working load of any rope is much lower than its nominal strength. In life threatening and similar critical conditions, the safe working load should not exceed 1/15 of the rated breaking strength. In non-life threatening applications, a safe working load of 1/5 of the rated strength may be acceptable.
