Introduction
This document is a type C standard as stated in EN ISO 12100.
This document has been prepared to be a harmonized standard to provide a means of complying with the
essential safety requirements of the Lifts Directive and the Machinery Directive.
During the preparation of this standard, it was assumed that a negotiation would take place between the
purchaser and the manufacturer concerning the intended purpose of the rope.
Although tables of breaking forces and masses are provided for a number of the more common classes,
diameters and rope grades, this Part of this standard is not limited to those given, providing all of the
other requirements are met.
When provisions of this type C standard are different from those which are stated in type A or B
standards, the provisions of this type C standard take precedence over the provisions of the other
standards for wire ropes that have been designed and produced according to the provisions of this type
C standard.

The rope grade shall reflect the tensile strength grades of the outer and inner wires respectively, e.g.
rope grade 1370/1770 signifies a dual tensile rope having outer wires of tensile strength grade 1370
2 2
N/mm and inner wires of tensile strength grade 1770 N/mm and rope grade 1570 signifies a single
2
tensile rope having outer and inner wires of tensile strength grade 1570 N/mm .
For the more common classes of rope, the rope grade, R , shall be used in the calculation of minimum
r
breaking force of single tensile ropes and the rope value R shall be used in the calculation of minimum
dt
breaking force of dual tensile ropes, see Annex A for values of R .
dt
The rope grades for the various duties shall be in accordance with 5.3.3.2 to 5.3.3.4.
5.3.3.2 Suspension ropes
The rope grade shall be one of the following:
a) for traction drive lifts, see Tables 6 to 8
Rope with fibre core: 1180/1770; 1370/1770; 1570; 1770
Rope with steel core: 1370/1770; 1570/1770; 1570; 1770
b) for roped hydraulic lifts, see Tables 6 to 8
Rope with fibre core: 1370/1770; 1770
Rope with steel core: 1370/1770; 1570/1770; 1770
5.3.3.3 Governor ropes
The rope grade shall be one of the following: 1370/1770; 1570/1770; 1570 or 1770, see Tables 6 to 8.

5.3.3.4 Compensating ropes
The ropes grade shall be one of the following: 1370/1770; 1570 or 1770, see Tables 6, 7, 9 and 10.
5.4 Diameter
5.4.1 Tolerances
When measured in accordance with 6.3.1 of EN 12385-1:2002+A1:2008, the actual diameter under no
load and under a load equivalent to 5 % or 10 % of the minimum breaking force of the rope shall not
vary from the nominal diameter by more than the values given in Tables 2, 3 or 4, as appropriate.
