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, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 17558 was prepared by Technical Committee ISO/TC 105, Steel wire ropes. This first edition of ISO 17558 cancels and replaces ISO 7595:1984 and ISO/TR 7596:1982, of which it constitutes a technical revision.

With an increasing use of resin as a socketing medium, opportunity was taken to review and update the requirements formerly given by ISO/TR 7596. Each socket design should be used only with the appropriate method or methods of socketing which have been proven as being satisfactory by prototype testing. Sockets, if properly attached to the wire rope, should sustain the full breaking force of the rope. This is important because accidental release of a load due to failure of a rope termination could create a hazard.

It also specifies a type testing method for assessing the performance of a socketing system. The procedures described in this International Standard are for use with sockets having a strength exceeding that of the minimum breaking force of the rope to be socketed and made from a material that remains unchanged when the socketing media is hot metal. Operating temperature limits for ropes socketed with lead-based alloys, zinc and zine-based alloys and resin are given for information in Annex E. 2 Normative references The following referenced documents are indispensable for the application of this document.

Additional servings or additional length of serving may be required for spiral rope. Two types of serving shall be used as follows. Temporary servings shall be used to hold the strands and wires in position during the cutting operation. A permanent serving shall be used to hold the strands and wires in position during the socketing operation. The permanent serving shall be in position before cutting the rope. The position of the permanent serving shall permit the correct positioning of the brush in relation to the socket. NOTE The permanent serving is attached to that part of the rope which remains partly within the bore or immediately adjacent to the base of the socket when the socketing has been completed.

When serving wire or strand is used for permanent serving it shall be tinned or galvanized soft wire or strand for galvanized rope, and bright, tinned or galvanized soft wire or strand for bright rope. Copper and brass wires shall not be used for servings. Materials used for permanent serving shall preserve the rope lay and shall not cause deleterious electrolytic reaction in service. The serving material shall be capable of withstanding the temperature involved in the socketing procedure. 4.2 Cutting of rope The wire rope shall be cut by abrasive wheel, percussive or shearing methods, paying particular attention not to disturb the position of the wires below the permanent serving. Cutting methods that fuse the wire rope end shall not be used. 4.3 Preparation of the socket Dirt, grease, scale or residues shall be removed from the inside of the socket basket. NOTE This does not preclude the use of a releasing agent when socketing with resin. 4.4 Inserting rope into socket One of two procedures shall be used to insert the rope into the socket. In the first method, the rope shall be inserted into the socket prior to the preparation of the brush. In the second method, after the brush has been prepared in accordance with 4.6, it shall be closed and compacted to enable it to be inserted into the bore of the socket without damaging the rope. 4.5 Preparation of the brush The temporary serving at the point of cut shall be removed and the strands fanned outwards to allow opening of the wires. The rope including any steel core shall be unlaid into its constituent wires to form an open brush. See Figure 2. Wires should not be bent to an excessive angle at the permanent serving, since this can cause premature failure. The opening angle of the brush should not exceed 45° from the vertical, see Figure 2. Special care should be taken with locked-coil rope due to the sensitivity of the lock coil wire section. When socketing fibre core ropes or ro
