Price based on 3 pages No reproduction or networking permitted without license from IHS Not for Resale Foreword Iso (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through IsO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, govern- mental and non-governmental, in liaison with Iso, also take part in the work. Draft International Standards adopted by the technical committees are circuiated to the member bodies for approval before their acceptance as International Standards by least 75 % approval by the member bodies voting. International Standard ISO 8793 was prepared by Technical Committee ISO/TC 105, Steel wire ropes. Users should note that all International Standards undergo revision from time to time and that any reference made herein to any other International Standard implies its latest edition, unless otherwise stated.

The eye termination may be made either as a Flemish eye or a turn back loop. Prototype tests covering the type acceptance of ferrule-secured systems and routine quality control requirements for ferrule- secured eye terminations are also specified in this International Standard. 2 Reference ISO 2408, Steel wire ropes for general purposes Characteristics. 3 Definitions 3.1 ferrule-secured eye termination (mechanically Figure 2- Turn back loop spliced) : Eye termination made by forming an eye, which is secured by means of a ferrule pressed on the rope. There are two main types : the Flemish eye and the turn back loop. 3.2 sponsor : The person or organization which takes responsibility for the material, design, dimensions, identifica- tion, prototype testing and manufacture of the ferrule and the 3.1.1 Flemish eye : Eye termination where the rope end is specification of the method of application to wire ropes. split in two parts of three or four strands each, which are laid together again in the opposite direction, forming an eye which is symmetrical to the rope axis. The tails of the strands are Types of wire ropes distributed equaly around the main body of the rope. They are fixed in this position by means of a ferrule (see figure 1). All steel wire ropes for general purposes complying with ISo 2408 may be fitted with a ferrule-secured eye termination; however, the rope shall be suitably pre-formed for Flemish eyes and pre-forming is also recommended for turn back loops. Ferrules Electric welding of steel tubes for ferrules used on the Flemish eye is permitted provided that the welding is carried out prior to the tube drawing and annealing operations. Ferrules of aluminium or copper shall be produced by a process which gives a completely s
