BS EN 12385-4:2002+A1:2008EN 12385-4:2002+A1:2008 (E) 4 Introduction This Part of this European Standard has been prepared to be a harmonized standard to p

23、rovide 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

24、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 purchas

25、er 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 me

26、t. 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 gene

27、ral 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 ter

28、minations. 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 app

29、ropriate 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 pub

30、lication referred to applies (including amendments). EN 10264-2, Steel wire and wire products Steel wire for ropes Part 2: Cold drawn non-alloyed steel wire for ropes for general applications.

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 ro

36、pe 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.

39、 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 sp

40、ecified 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 i
