1 Scope

This Part of this European Standard specifies the additional materials, manufacturing and testing requirements to those given in Part 1 for spiral ropes incorporating zinc or zinc alloy coated wires for general structural applications.

This standard deals with all significant hazards, hazardous situations and events relevant to spiral ropes for general structural applications, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see clause 4 of EN 12385-1:2002).

This standard applies to spiral ropes for general structural applications which are manufactured after the date of its publication.

NOTE For information only, typical breaking forces for both full-locked coil rope and spiral strand rope are given in annexes В and C for some of the more common sizes.

5.2    Wire

5.2.1    General

Wires before ropemaking, shall conform to the requirements given in 5.2.2 and 5.2.3 taking into account the wire, shape and class of coating.

5.2.2    Round wires

Wires of class A coating shall conform to EN 10264-2; or alternatively, in the case of final hot zinc coated wires, meet the diameter, tensile strength and coating requirements given in EN 10264-2 and the ductility and adherence wraps and % total elongation at fracture properties given in annex A of this Part of the standard.

5.3    Rope manufacture

5.3.1    Wire joints

There shall be no planned joints in the outer layer of wires in any individual in-service rope length or assembly.

In any individual in-service rope length or assembly, welds of finished wire in the outer layer shall be no closer than 10 lay lengths of each other and no weld shall be within one lay length of the entry point of the rope into the termination.

The tensile strength of the weld shall be at least 50 % of the tensile strength grade of the wire. This shall be verified by testing a sample weld made in accordance with the same method as used to join the wire(s) in the rope._

Outer wire joints shall be protected against corrosion by coating.

5.3.2    Wire finish

The finish of the wires shall be either zinc or zinc alloy coated or a combination of both provided that in any one layer of wires the finish is the same.

When measured in accordance with 6.3.1 of EN 12385-1:2002 the measured diameter shall be within 0 % and +3 % of the nominal diameter.

NOTE Specifiers, purchasers and users should recognize that spiral ropes for structural applications are, more often than not, specially designed by the rope manufacturer to meet particular conditions and particular attention should be given to the selection of the correct size of rope and associated diameter tolerance for compatibility with other components, such as sockets.
