1 Scope

This Part of this European Standard specifies the particular materials, manufacturing and testing requirements for ropes for general lifting applications.

The particular hazards covered by this Part are identified in Clause 4.

This Part of this European Standard does not establish requirements for information for use other than those given in clause 7 of Part 1. Neither does it cover the requirements for ropes fitted with terminations.

Minimum breaking force values for the more common classes, sizes and grades of rope are provided in tables 5 to 17.

2 Normative references

This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments).

3    Terms and definitions

For the purposes of this European Standard, the terms and definitions in EN 12385-2 apply.

4    Hazards

In addition to the general hazards identified in clause 4 of Part 1, Table 1 contains all the particular hazards which require action to reduce risk as being specific and significant for steel wire ropes for general lilting applications.

Table 1 - Hazards and associated requirements

Hazards identified in annex A of EN 1050:1996 Relevant clause of annex A of EN 292-2:1991/A1:1995 Relevant clause of this standard 27.4 Mechanical hazard from insufficient strength of parts 4.1.2.3 5 and 6 27.6 Mechanical hazard from inadequate selection of ropes and their inadequate integration into the machine 4.3.1 7

NOTE For the purposes of this Part of EN 12385, insufficient strength of parts means failure to achieve the minimum breaking force of the rope.

5 Safety requirements and/or measures

5.1    General

In addition to the requirements given 5.2 to 5.5, the requirements shall also conform to those given in EN 12385-1.

5.2    Materials

5.2.1 Wire

Wires, before ropemaking, shall conform to EN 10264-2.

For those ropes where a rope grade is applicable, e.g. Tables 5 to 16, the tensile strength grades of the wires shall be subject to the limits given in Table 2.

For those ropes where a rope grade is not applicable, e.g. large diameter ropes, the tensile strength grades of the wires shall be one or a combination of those given in EN 10264-2.

Table 2 — Wire tensile strength grades excluding centre and filler wires for given rope grades

Rope Grade Wire tensile strength grades N/mm^ Minimum Maximum 1770 1570 1960 1960 1770 2160 2160 1960 2160

СТБ EN 12385-4-2009

5.2.2    Core

The core shall be one of the following types:

a)    fibre;

b)    steel, as an independent wire rope (IWRC) or wire strand (WSC);

c)    composite (e.g. steel and fibre or steel and solid polymer);

d)    cushion core; or

e)    solid polymer.

5.2.3    Lubricant

The lubricant shall comply with ISO 4346.

5.3    Rope manufacture

5.3.1    Lubrication

At least the strands shall be lubricated.

5.3.2    Construction

The rope construction shall be either:

a)    one of those covered by Tables 5 to 17; or

b)    another single layer or parallel-closed or rotation-resistant rope construction as specified by the manufacturer and covered by the respective classes in EN 12385-2.

5.3.3    Rope grade

For rope sizes up to and including 60 mm diameter, the rope grade shall be 1770, 1960 or 2160 or an intermediate grade as specified by the manufacturer, but not exceeding 2160.

NOTE Ropes larger than 60mm diameter may not have a rope grade.

5.4 Diameter 5.4.1 Tolerances

When measured in accordance with 6.3.1 of EN 12385-1:2002, the measured diameter shall not vary from the nominal diameter by more than the values given in Table 3. For ropes with diameters from 2 mm to 5 mm inclusive, the tolerance shall be rounded up to the nearest 0,05 mm.

Table 3 — Tolerances on rope diameter

Nominal rope diameter mm Tolerance as percentage of nominal rope diameter From 2 to < 4 +8 0 From 4 to < 6 +7 0 From 6 to < 8 +6 0 8 and greater +5 0

5.4.2 Differences between diameter measurements

The difference between any two of the four measurements taken in accordance with 6.3.1 of EN 12385-1:2002 and expressed as a percentage of the nominal rope diameter, shall not exceed the values given in Table 4.

Table 4 — Differences between diameter measurements

Nominal rope diameter mm Difference between measurements as percentage of nominal rope diameter Rope with strands that are exclusively of wire or incorporate solid polymer Ropes with strands that incorporate fibre centres From 2 to < 4 7 - From 4 to < 6 6 8 From 6 to < 8 5 7 8 and greater 4 6

NOTE The values in the table apply irrespective of the type of core in the rope.

5.5    Breaking force

The breaking force shall be specified only as minimum breaking force.

The values of minimum breaking force for the more common classes and grades of ropes shall be not less than those given in Tables 5 to 16. For intermediate rope diameters, the values shall be not less than those obtained using the formula in annex A with the factors given in annex B.

The values of minimum breaking force for large diameter ropes are given in Table 17. For intermediate rope diameters, the values shall be not less than those obtained using the formula in annex A.

NOTE Refer to the definitions given in EN 12385-2 for derivation of the formula for calculation of minimum breaking force.

5.6    Designation and classification

Rope designation and classification shall conform to EN 12385-2.

6 Verification of safety requirements and/or measures

6.1    General

Verification of safety requirements and/or measures shall be in accordance with that given in clause 6 of EN 12385-1 and the additional verification given in 6.2 to 6.5 below.

6.2    Lubricant

Compliance with the lubricant requirements shall be through a visual verification of the inspection documents supplied with the lubricant.

6.3    Lubrication

Compliance with the lubrication requirements shall be through a visual verification.

6.4    Construction

Compliance with the construction requirements shall be through a visual verification.

6.5    Rope grade

Compliance with the rope grade requirements shall be through a visual verification of the inspection documents supplied with the wire in relation to the minimum breaking force value of the rope.

7 Information for use

In addition to conforming to clause 7 of Part 1, the Certificate (see 7.2.1 of Part 1) shall also include either an example of the maximum working load to which the rope shall be subjected in service at a given factor of safety or the working load limit when the intended use is known.
