EN 12385-4:2002 (E)4IntroductionThis Part of this European Standard has been prepared to be a harmonized standard to provide one means ofcomplying 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 safetyfactor of 5. The safety factor and the required minimum breaking force of the rope for a given application is theresponsibility 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 purchaserand 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, diametersand rope grades, this Part of this standard is not limited to those given, providing all of the other requirements aremet.Specifiers, purchasers and users should recognise that some ropes are specially designed by the manufacturer tomeet particular lifting machinery requirements.1 ScopeThis Part of this European Standard specifies the particular materials, manufacturing and testing requirements forropes 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 givenin 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 to17.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text, and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision. For undated references the latest edition of thepublication 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 forropes for general applications.EN 12385-1:2002, Steel wire ropes – Safety – Part 1: General requirements.EN 12385-2:2002, Steel wire ropes – Safety – Part 2: Definitions, designation and classification.ISO 4346, Steel wire ropes for general purposes – Lubricants – Basic requirements.
