17、dwide 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

18、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 i

19、n 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

20、 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 2408 was prepared by Tec

21、hnical Committee ISO/TC 105, Steel wire ropes. This third edition cancels and replaces the second edition (ISO 2408:1985), which has been technically revised. ISO 2408:2004(E) ISO 2004 All rights reserved vIntroduction This International Standard was developed in response to a worldwide demand for a

22、 specification giving minimum requirements for ropes for general purposes. As in previous editions, this edition of ISO 2408 specifies metric sizes and grades of rope for the more common classes of rope. In addition, and for comparison, information is given in this edition on imperial rope sizes and

23、 grades in order to assist in the rope selection process and help to ensure that existing levels of safety are maintained on equipment originally designed to use such ropes. In these cases, it is recommended that the equipment designer or rope manufacturer (or other competent person) be consulted pr

24、ior to ordering a substitute rope. This International Standard does not restrict itself to those classes covered by the tables: other types, such as ropes with compacted strands and compacted (swaged) ropes, may also conform to it. Complementing this International Standard is ISO 17893, which covers

25、 definitions, designation and classification. INTERNATIONAL STANDARD ISO 2408:2004(E) ISO 2004 All rights reserved 1Steel wire ropes for general purposes Minimum requirements 1 Scope This International Standard specifies minimum requirements for the manufacture and testing of stranded steel wire rop

26、es for general purposes, including lifting equipment such as cranes and hoists. Ropes for slings are also dealt with, and tables giving minimum breaking forces for the more common sizes, grades and constructions of stranded rope presented. It is applicable to single-layer, rotation-resistant and par

27、allel-closed ropes made from wires of uncoated (bright), zinc-coated and zinc-alloy coated finish in rope diameters of up to 60 mm, supplied as bulk manufacture. It is not applicable to ropes for mining purposes, aircraft control, the petroleum and natural gas industries, aerial ropeways and funicul

28、ars, lifts, or fishing purposes. 2 Normative references The following referenced documents are indispensable for the application of this document.

32、Before ropemaking, wires shall conform to the diameter, torsion and, where applicable, coating requirements specified in Annex A. NOTE 1 Annex A is based on ISO 2232 but with extended wire sizes and wire tensile strength grades. NOTE 2 For a given wire size and tensile strength grade, the torsional

33、properties of the wires in A.2 of ISO 10425:2003 meet or exceed the values given in Annex A of this International Standard. For those ropes where a rope grade is applicable, the tensile strength grades of the wires shall be subject to the limits given in Table 1. Table 1 Tensile strength grades of w

34、ires (excluding centre and filler wires) for given rope grades Rope grade Range of wire tensile strength gradesN/mm21570 1 370 to 1 770 1770 1 570 to 1 960 1960 1 770 to 2 160 2160 1 960 to 2 160 NOTE 3 The minimum breaking force values of those ropes of grades 1570, 1770, 1960 and 2160 as covered b

35、y Tables C.1 to C.14 are calculated on the basis of rope grade and not individual wire tensile strength grades. All wires of the same nominal diameter in the same wire layer shall be of the same tensile strength grade. The methods of test shall be in accordance with ISO 2232. 4.1.2 Core Cores of sin

36、gle-layer stranded ropes shall normally be of steel or fibre, although other types such as composites (e.g. steel plus fibre or steel plus polymer) or solid polymer may also be supplied. The purchaser should specify any particular core type requirements. Fibre cores for single-layer stranded ropes s

37、hall conform to ISO 4345 and for rope diameters 8 mm and above shall be doubly closed (i.e. from yarn into strand and from strand into rope). Natural fibre cores shall be treated with an impregnating compound to inhibit rotting and decay. Steel cores shall be either an independent wire rope (IWRC) o

38、r a wire strand (WSC). Steel cores of single-layer stranded ropes larger than 12 mm diameter shall be an independent wire rope (IWRC), unless specified otherwise. ISO 2408:2004(E) ISO 2004 All rights reserved 34.1.3 Lubricant Lubricants shall conform to ISO 4346. 4.2 Rope manufacture 4.2.1 General A

39、ll the wires in a strand shall have the same direction of lay. The core, except for compacted (swaged) ropes, shall be designed (steel) or selected (fibre) so that in a new rope under tension on the closing machine there is clearance between the outer strands. The completed rope shall be evenly laid

40、 and free from loose wires, distorted strands and other irregularities. When uncoiled and under no load the rope shall not be wavy. Rope ends that have no end fittings shall, when necessary, be so secured as to maintain the integrity of the rope and prevent its unravelling. 4.2.2 Wire joints Wires o

41、ver 0,4 mm in diameter shall, where necessary, have their ends joined by brazing or welding. Wires up to and including 0,4 mm diameter shall, where necessary, be joined by brazing, welding, twisting or by ends being simply inserted in the strands formation. If twisting as a joint is performed during

42、 rope manufacture, any protruding twisted wire ends shall be removed from the finished rope. 4.2.3 Lubrication The amount of lubrication and type of lubricant shall be appropriate to the rope duty. The purchaser should specify the rope duty or any particular lubrication requirements. 4.2.4 Preformat

43、ion and postformation Ropes shall be preformed and/or postformed unless specified otherwise by the purchaser. NOTE Some parallel-closed and rotation-resistant ropes could be non-preformed or be only partially preformed. 4.2.5 Construction The rope construction shall be either one of those covered by

44、 the following classes or a construction, including compacted strand ropes and compacted (swaged) ropes, as stated by the manufacturer: 6 7, 6 24FC, 6 37M, 6 19, 6 36, 8 19, 8 36, 6 25TS, 18 7, 34(M) 7 and 35(W) 7. Where only the rope class is specified by the purchaser the construction supplied sha

45、ll be decided by the manufacturer. The purchaser should specify the rope construction or class. 4.2.6 Grade The rope grades for the more common classes of ropes shall be as given in Tables C.1 to C.14. ISO 2408:2004(E) 4 ISO 2004 All rights reservedIntermediate rope grades, including those as given

46、in ISO 10425, may be supplied by agreement between the purchaser and the manufacturer providing all of the other requirements are met. NOTE Not all ropes will necessarily have a rope grade. 4.2.7 Wire finish The finish of the wires shall be uncoated (bright), zinc-coated Quality B or zinc coated Qua

47、lity A. For ropes of bright wire finish, substitution of bright wires by zinc-coated wires shall be limited to inner wires, centre wires, filler wires and core wires. For ropes of zinc coated wire finish, all of the wires shall be zinc coated, including those of any steel core. Where zinc-coated is

48、specified this may also include zinc alloy Zn95/Al5. 4.2.8 Direction and type of lay The direction and type of rope lay shall be one of the following: a) right ordinary lay (sZ)2); b) left ordinary lay (zS)3); c) right lang lay (zZ)4); d) left lang lay (sS)5); The direction and type of rope lay shou
