Strand types3.2.1strandan element of rope consisting of an assembly of wires of appropriate shape and dimensions laid helically in thesame direction in one or more layers around a centreNOTEStrands containing three or four wires in the first layer, or certain shaped strands (e.g. ribbon) cannot have a centre.

b) Strand with (1-6) built-up centreFigure 1 — Round strand with different centres3.2.3triangular strand (V)a strand with a perpendicular cross-section which is approximately the shape of a triangle, see Figure 2Figure 2 — Triangular strand with triangular (V) centre wireNOTETriangular strands can have built-up centres e.g. 3 ´ 2 + 3F, K1V-6, K3/9 etc.3.2.4oval strand (Q)a strand having a perpendicular cross-section which is approximately the shape of an oval, see Figure 3Figure 3 — Oval strand having oval shaped centre

Core types3.3.1core (C)central element of a round rope around which are laid helically the strands of a stranded rope or the unit ropes of acable laid rope3.3.2fibre core (FC)core made from either natural fibres (NFC) or synthetic fibres (SFC)NOTEFibre cores are normally produced in the sequence fibres to yarns, yarns to strands and strands to rope.3.3.3steel core (WC)core made from steel wires arranged as a wire strand (WSC) or as an independent wire rope (IWRC)NOTEThe steel core and/or its outer strands can also be covered with either fibre or solid polymer.3.3.4solid polymer core (SPC)core consisting of a solid polymer material having a round shape or a round shape with grooves. It may alsocontain an internal element of wire(s) or fibre3.4 Lubricants and preservation agents3.4.1rope lubricanta material applied during the manufacture of a strand, core or rope for the purpose of reducing internal frictionand/or assisting in providing protection against corrosion3.4.2impregnating agenta material used in the manufacture of natural fibre cores, coverings and inserts for the purpose of inhibiting rottingand decay

Rope types3.6.1
Stranded ropes3.6.1.1stranded ropean assembly of several strands laid helically in one or more layers around a core (single-layer rope) or centre(rotation-resistant or parallel-closed rope).NOTEStranded ropes consisting of three or four outer strands can, or cannot, have a core. 3.6.1.2single-layer ropestranded rope consisting of one layer of strands laid helically around a core, see Figure 11Figure 11 — Examples of single-layer stranded ropes3.6.1.3rotation-resistant ropestranded rope designed to generate reduced levels of torque and rotation when loaded see Figure 12NOTE 1Rotation-resistant ropes generally comprise an assembly of at least two layers of strands laid helically around acentre, the direction of lay of the outer strands being opposite to that of the underlying layer.NOTE 2Ropes having three or four strands can also be designed to exhibit rotational-resistant properties.NOTE 3Rotation-resistant ropes have previou
