EN 12385-5:2002 (E) 4 Introduction This Part of this European Standard has been prepared to be a harmonized standard to provide one means of complying with the es
21、sential safety requirements of the Lift Directive. This Part of this European Standard is a type C standard as stated in EN 292. 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 t
22、he 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. 1 Scope This Part of this European Standard specifies the
23、 particular materials, manufacturing and testing requirements for stranded ropes for suspension, compensating and governor duties for traction drive and hydraulic lifts moving between guides. The particular hazards covered by this Part are identified in Clause 4. This Part of this European Standard
24、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 6 to 10. 2 Norma
25、tive 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
26、 any of these publications apply to this European Standard only when incorporated in it by amendment or revision.
