Introduction This Part of this European Standard has been prepared to be a harmonized standard to provide one means of complying with the essential safety requirements of the Machinery Directive. This Part of this European Standard is a type C standard as stated in EN 292. For the purposes of the Certificate referred to in clause 7, this Part assumes a working load limit based on a safety factor of 5. The safety factor and the required minimum breaking force of the rope for a given application is the responsibility of the manufacturer of the machine of which the rope forms a part. During the preparation of this standard, it was assumed that a negotiation would take place between the purchaser and the manufacturer concerning the intended purpose of the rope. Although tables of breaking forces and masses are provided for a number of the more common classes, diameters and rope grades, this Part of this standard is not limited to those given, providing all of the other requirements are met. Specifiers, purchasers and users should recognise that some ropes are specially designed by the manufacturer to meet particular lifting machinery requirements.
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).

Mechanical hazard from inadequate selection of ropes and their inadequate integration into the machine
4.1.2.3
4.3.1 5 and 6
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.

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.

mm Tolerance as percentage of nominal rope diameter From 2 to < 4 08+ From 4 to < 6 07+ From 6 to < 8 06+ 8 and greater 05+
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.

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.
