EN ISO 10556 Fibre ropes of polyester /polyolefin dual fibres

1 Scope

This International Standard specifies requirements for 3-strand hawser-laid, 8-strand and 12-strand braided
fibre ropes made of polyester in combination with polyolefin, and gives rules for their designation.

2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 1968 apply.

4 Designation
Fibre ropes shall be designated by the following:
⎯ the words “fibre rope”;
⎯ the number of this International Standard;
⎯ the construction or type of the rope (see Clause 6);
⎯ the reference number of the rope;
⎯ the materials from which the rope is made;
⎯ the level of performance of the rope: fibre rope or higher-strength (hs) fibre rope.
EXAMPLE 1 Designation of a 3-strand hawser-laid rope, reference number 20 (type A), corresponding to a linear
density of 194 ktex, made of polyester/polyolefin dual fibre:

5 Materials
5.1 Fibres
5.1.1 Polyester: the polyester portion of the rope shall be a continuous multifilament, heat- and lightresistant fibre of industrial (high tenacity) grade.
5.1.2 Polyolefin: the polyolefin portion of the rope shall be of suitable tenacity to meet all the requirements
of this International Standard.
NOTE Polyolefin can be polypropylene, or a mixture of polypropylene and polyethylene with a minimum of 15 % and a
maximum of 50 % of polyethylene.
5.2 Yarns
5.2.1 The cover yarns of each strand of fibre ropes shall be made with polyester fibres covering a
polyolefin core and shall contain a minimum of 40 % by mass of polyester fibre (see Table 1).
NOTE When interior yarns are used, they may consist of 100 % polyolefin fibres.
5.2.2 All the yarns used in higher-strength fibre ropes shall be made with polyester fibres covering a
polyolefin core and shall contain a minimum of 40 % by mass of polyester fibre (see Table 2).

6 General requirements
6.1 Polyester/polyolefin dual-fibre ropes shall be constructed in one of the following ways:
⎯ type A: 3-strand hawser-laid rope (see Figure 1);
⎯ type L: 8-strand braided rope (see Figure 2);
⎯ type T: 12-strand braided rope (see Figure 3).
