4 Introduction This part of this European Standard has been prepared to support Parts 4 to 10 that concern themselves with the particular requirements for steel wire ropes for use in specific applications. The rope designation system described in clause 4 is provided with the intention of it being used to describe the rope in the certificate or inspection document referred to in the other Parts. The rope classification system described in clause 5 is provided to define which constructions apply to a specific rope class. The designation and classification systems described in clauses 4 and 5 respectively may also be used for ropes not covered by the other parts of this standard. 1 Scope This part of this European Standard defines terms, specifies designations and classifies steel wire ropes and is for use in conjunction with all other parts of this standard. It applies to ropes that have been manufactured after the date of issue of the standard. 2 Normative references Not applicable. 3 Terms and definitions For the purposes of this part of EN 12385, the following terms and definitions apply. 3.1 Wires 3.1.1 outer wires all wires positioned in the outer layer of a spiral rope or in the outer layer of wires in the outer strands of a stranded rope 3.1.2 inner wires all wires of intermediate layers positioned between the centre wire and outer layer of wires in a spiral rope or all other wires except centre, filler, core and outer wires in a stranded rope 3.1.3 filler wires wires used in filler constructions to fill up the interstices between wire layers, see Figure 8 3.1.4 centre wires wires positioned either at the centre of a spiral rope or the centres of strands of a stranded rope 3.1.5 core wires all wires of the core of a stranded rope 3.1.6 load-bearing wires those wires in a rope which are regarded as contributing towards the breaking force of the rope
wire tensile strength grade (R) a level of requirement of tensile strength of a wire and its corresponding range. It is designated by the value according to the lower limit of tensile strength and is used when specifying wire and when determining the calculated minimum breaking force or calculated minimum aggregate breaking force of a rope, expressed in N/mm2 3.1.11 wire tensile strength (Rm) the ratio between the maximum force obtained in a tensile test and the nominal cross-sectional area of the test piece, expressed in N/mm2 3.1.12 finish and quality of coating the condition of the surface finish of the wire e.g. uncoated (bright), zinc coated, zinc alloy coated or other protective coating and the class of coating, e.g. class B zinc coating, defined by the minimum mass of coating and the adherence of the coating to the steel below 3.1.13 mass of coating the mass of coating (obtained by a prescribed method) per unit of surface area of the uncoated wire, expressed in g/m2 3.2
Strand types 3.2.1 strand an element of rope consisting of an assembly of wires of appropriate shape and dimensions laid helically in the same direction in one or more layers around a centre NOTE Strands containing three or four wires in the first layer, or certain shaped strands (e.g. ribbon) cannot have a centre.
3.2.2 round strand a strand with a perpendicular cross-section which is approximately the shape of a circle, see Figure 1
a) Strand with one centre wire
b) Strand with (1-6) built-up centre Figure 1 — Round strand with different centres 3.2.3 triangular strand (V)
a strand with a perpendicular cross-section which is approximately the shape of a triangle, see Figure 2
Figure 2 — Triangular strand with triangular (V) centre wire NOTE Triangular strands can have built-up centres e.g. 3 × 2 + 3F, K1V-6, K3/9 etc. 3.2.4 oval strand (Q)
a strand having a perpendicular cross-section which is approximately the shape of an oval, see Figure 3

3.2.5 flat ribbon strand (P) a strand without a centre wire with a perpendicular cross-section which is approximately the shape of a rectangle, see Figure 4
Figure 4 — Flat ribbon strand 3.2.6 single lay strand
strand which contains only one layer of wires, see Figure 5
Figure 5 — Single lay strand 3.2.7 parallel lay strand
strand which contains at least two layers of wires, all of which are laid in one operation (in the same direction) NOTE 1 Also known as equal lay. NOTE 2 The lay length of all the wire layers is equal and the wires of any two superimposed layers are parallel resulting in linear contact.
8 3.2.8 Seale
parallel lay strand construction with the same number of wires in both layers, see Figure 6
Figure 6 — Seale construction 3.2.9 Warrington parallel lay strand construction having an outer layer containing alternately large and small wires and twice the number of wires as the inner layer, see Figure 7
Figure 7 — Warrington construction 3.2.10 filler parallel lay strand construction having an outer layer containing twice the number of wires than the inner layer, with filler wires laid in the interstices between the layers, see Figure 8
Figure 8 — Filler construction
3.2.11 combined parallel lay parallel lay strand construction having three or more layers laid in one operation and formed from a combination of the strand types 3.2.8 to 3.2.10, see Figure 9.
Figure 9 — Combined parallel lay, example: Warrington - Seale
3.2.12 multiple operation lay strand
construction containing at least two layers of wires in which successive layers are laid in more than one operation 3.2.13 cross-lay (M)
strand which contains more than one layer of wires, all laid in the same direction. The wires of superimposed wire layers cross one another and make point contact 3.2.14 compound lay (N)
strand which contains a minimum of three layers of wires, the outer layer of which is laid in a separate operation, but in the same direction as the others, over a parallel lay construction forming the inner layers
3.2.15 compacted strand (K) a strand which has been subjected to a compacting process such as drawing, rolling or swaging whereby the metallic cross-sectional area of the wires remains unaltered whereas the shape of the wires and the dimensions of the strand are modified, see Figure 10
a) Strand before compacting b) Strand after compacting Figure 10 — Compacted round strand
3.3
Core types 3.3.1 core (C) central element of a round rope around which are laid helically the strands of a stranded rope or the unit ropes of a cable laid rope 3.3.2 fibre core (FC) core made from either natural fibres (NFC) or synthetic fibres (SFC)
NOTE Fibre cores are normally produced in the sequence fibres to yarns, yarns to strands and strands to rope. 3.3.3 steel core (WC)
core made from steel wires arranged as a wire strand (WSC) or as an independent wire rope (IWRC) NOTE The steel core and/or its outer strands can also be covered with either fibre or solid polymer. 3.3.4 solid polymer core (SPC)
core consisting of a solid polymer material having a round shape or a round shape with grooves. It may also contain an internal element of wire(s) or fibre 3.4 Lubricants and preservation agents 3.4.1 rope lubricant
a material applied during the manufacture of a strand, core or rope for the purpose of reducing internal friction and/or assisting in providing protection against corrosion 3.4.2 impregnating agent a material used in the manufacture of natural fibre cores, coverings and inserts for the purpose of inhibiting rotting and decay
a material, usually some form of blocking compound, applied during and/or after manufacture of the rope and/or to fibre inserts and coverings for the purpose of providing pr
