3 Terms and definitions
For the purposes of this part of EN 12385, the terms and definitions in part 2 of EN 12385 shall apply.
4 List of hazards
The release of a load due to failure of steel wire ropes puts at risk directly or indirectly the safety or health of those
persons within the danger zone.
In order to provide the necessary strength and durability of steel wire ropes, the other Parts of this standard lay
down the particular requirements for the materials, manufacture, physical dimensions, mechanical properties and
testing to ensure that specified levels of performance are met.
Fatigue failure has not been identified as a hazard for steel wire rope.
Since failure can be caused by the incorrect choice of specification of steel wire ropes, the other Parts of this
standard, in association with this Part, give the particular requirements for marking and the information that is
required to be stated on the manufacturer’s certificate.
The particular hazards for the various rope applications are given in the other Parts.

5 Safety requirements and/or measures
5.1 Materials
5.1.1 Wire
5.1.1.1 Before ropemaking
All wires of the same size and shape in the same wire layer shall be of the same tensile strength grade.
For intermediate wire tensile strength grades the reverse bend and torsion properties shall be as for the next higher
grade.
5.1.1.2 After ropemaking
When other parts of this standard require tests to be carried out on wires taken from the rope, sampling, test
methods and acceptance criteria shall be in accordance with annex B.
5.1.2 Core
Fibre cores (FC) shall comply with ISO 4345 unless specified otherwise in the appropriate part of this standard.
Fibre cores (FC) for single layer stranded ropes larger than 8 mm diameter shall be doubly closed
Natural fibre cores (NFC) shall be treated with an impregnating compound to inhibit rotting and decay unless stated
that the core is dry.
5.2 Rope manufacture
5.2.1 Wire joints
When joints are necessary in wires over 0,4 mm they shall have their ends joined by brazing or welding.
For stranded ropes the minimum distance between joints within one strand shall be 18 rope diameter (d).
For spiral ropes the minimum distance between joints in any wire layer shall be 36 diameter of the wire layer.
If twisting as a joint is performed on wires up to and including 0,4 mm during manufacture, the twist shall be
removed from the finished rope.
NOTE 1 Wires up and including 0,4 mm can be joined by twisting or by the ends being simply inserted into the strand’s
formation.
NOTE 2 When joints in wires before closing are not accepted, this should be the subject of agreement (see introduction)
between the purchaser and the manufacturer.
5.2.2 Preformation
Single layer and parallel-closed ropes shall be preformed unless stated by the manufacturer that the rope is non-
preformed.
5.2.3 Wire finish
For ropes of bright wire finish, substitution of bright wires by zinc coated wires shall be limited to inner wires, centre
wires, filler wires and core wires.
For stranded ropes of zinc coated wire finish, all of the wires shall be zinc coated, including those of any steel core.
Quality B coating as given in EN 10244-2 shall be used for zinc coated wires unless specified otherwise in the
appropriate part of this standard.
5.2.4 Rope ends
Rope ends that have no end fittings shall be so secured as to maintain the integrity of the rope and prevent its
unlaying.

EN 12385-1:2002 (E)
5.3 Physical dimensions
5.3.1 Diameter or width and thickness
The nominal diameter for round ropes or the nominal width and thickness for flat ropes shall be the dimension(s) by
which the rope is designated.
5.3.2 Tolerances
When measured in accordance with 6.3 the measured diameter or the measured width and thickness shall not vary
from the nominal by more than the tolerance(s) specified in the appropriate part of this standard.
5.4 Breaking force
5.4.1 General
The minimum breaking force F or, where specified in the other parts of this standard, the minimum aggregate
min
breaking force F for a given size, grade (where applicable) and construction or class of rope shall be either,
e.min
a) in accordance with the value or calculation given in the appropriate part of this standard; or
b) as stated by the manufacturer.
When tested in accordance with Method 1 as described in 6.4.1 the measured breaking force F shall be equal to
m
or greater than the minimum breaking force F .
min
When tested in accordance with Method 2 as described in 6.4.2 the measured aggregate breaking force F shall
e.m
be equal to or greater than the minimum aggregate breaking force F
e.min.
When tested in accordance with Method 3 as described in 6.4.3 the calculated measured (post-spin) breaking force
F shall be equal to or greater than the minimum breaking force F .
m.c min
Unless specified otherwise in the appropriate part of this standard, breaking force testing shall be in accordance
with Table 1.
NOTE The requirements for breaking force testing take into account (i) the rope size, (ii) whether or not ropes are
produced in series i.e. repeatedly produced, (iii) whether or not the minimum breaking force factor is consistent throughout a
sub-group of rope diameters and (iv) whether or not the manufacturer is operating a quality system in accordance with EN ISO
9001 certified by an accredited third party certification body, see 5.4.2.
5.4.2 Ropes produced in series – manufacturer operating a quality system in accordance with EN
ISO 9001 certified by an accredited third party certification body
The manufacturer shall record the results from testing in accordance with the sampling and acceptance criteria as
detailed in annex A.
Additional production lengths of rope from any size grouping shall be deemed to comply with the breaking force
requirements when the manufacturer has satisfactorily completed a) the appropriate type tests, refer annex A and
b) a periodic test (see Table 1) in accordance with Method 1 or alternatively, Method 3, as described in 6.4, on a
sample from every twentieth production length or after re-starting of production, whichever is the sooner.
If any rope subject to the periodic test fails to meet or exceed the minimum value, testing of a sample from each
production length shall continue until the manufacturer satisfies the type testing requirements.
Any increase in breaking force factor for a particular construction shall also require that the type tests are repeated
on the modified ropes for each of the size bands. It shall not be necessary to repeat the tests if the same breaking
force factor is used for ropes using wires of a lower grade.
