This paper estimates the accuracy of relationships among strength properties (Rm—tensile strength) and technological ones (Nb—number of bends and Nt—number of bends) of steel wire for rope described in standard PN-EN10264. It uses new indicators for estimation of wire quality: Wb = Rm/Nb; Wt = Rm/Nt; and W = Wb + Wt. Application of these allows not only for estimation of wire quality and quality of strand and rope made from those wires, but also calculation of rope fatigue strength.
