15、irection of the Iron and Steel Standards Committee. It has been extensively revised to take account of ISO 2232:1973, ISO 3154:1976 and other work on the standardization of steel wire by the International Organization for Standardization (ISO) still in progress, where it is relevant to British pract
16、ice. BS 2763:1968 is now withdrawn. In line with current international practice, the term “zinc coated” has been adopted in this standard in place of “galvanized”. The terms are synonymous. A British Standard does not purport to include all the necessary provisions of a contract. Users of British St
17、andards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, pages 1 to 8, an inside back cover and a back cover. Thi
18、s standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover.

19、I BS 2763:1982 BSI 04-19991 Section 1. General 1 Scope This British Standard specifies requirements for cold drawn round carbon steel wire as supplied by the wire manufacturer for use in the manufacture of wire ropes. The specific requirements for wire for general purpose ropes, including those spec
20、ified in BS 302, BS 329, BS 365 and BS 3530, are given in section 2. The specific requirements for wire for high duty ropes that are subject to more exacting service conditions than general purpose ropes, and in particular for winding and certain haulage ropes complying with the requirements of BS 2
21、36 and BS 330 respectively, are given in section 3. Wires for both general and high duty purposes are available in a number of tensile strength grades over specific nominal diameter ranges (see Table 2 and Table 8). 2 References The titles of publications referred to in this standard are listed on t
22、he inside back cover. 3 Definitions For the purposes of this British Standard, the following definitions apply. 3.1 production coil a production coil of wire is that drawn from one coil of rod. It will usually be at least 800 kg but may be much greater in mass 3.2 package wire may be wound into coil
23、 form or on to spools. It may be wound on to collapsible spools from which it is removed as “cheeses” or, when wound on cardboard centre supports, as “spoolless cores”; the latter are suitable for fitting with flanges as a pay-off spool to avoid repetition of each term in this specification it is co
24、nvenient to describe all these forms by the word “package” 3.3 split package when, for the convenience of the ropemaker, a production coil is split into smaller pieces the latter are described as “split packages” 4 Information to be supplied by the purchaser When ordering wire complying with the req
25、uirements of this standard, the purchaser shall state the following: a) the number of this British Standard, i.e. BS 2763; b) the nominal diameter; NOTEThe nominal diameter of zinc coated wire includes the coating. c) the tensile strength grade; d) the type of finish, i.e. bright, class A (drawn zin
26、c coated or finally zinc coated) or class Z zinc coated, as defined in clause 7. Example: 3 mm diameter, class Z zinc coated wire having a minimum tensile strength of 1 570 N/mm2: BS 2763, 3 mm, grade 1 570, Z zinc coated. 5 Inspection and testing 5.1 General. All inspection and testing shall be car
27、ried out by the wire manufacturer and the record of each test shall be available to the ropemaker if required. 5.2 Selection of test pieces 5.2.1 For general purpose rope wire as specified in section 2, test pieces for all tests shall be cut from both ends of each production coil. Where the wire is
28、supplied in split packages, identified to the production coil, the tests on the production coil shall suffice for up to five split packages. If more than five split packages are taken from one production coil, two extra test pieces (not in adjacent positions) shall be taken from within the group of
29、split packages. 5.2.2 For high duty rope wire as specified in section 3, test pieces for all tests shall be cut from both ends of each package or split package as supplied to the ropemaker. 5.3 Test methods 5.3.1 General. All tests shall be carried out on straight pieces of wire. Any straightening w
30、hich may be required shall be done cold. The diameter of the wire shall be taken as the arithmetic mean of two micrometer readings made at right angles to each other. 5.3.2 Mechanical tests. Mechanical tests shall be carried out in accordance with the appropriate method described in BS 4545, except
31、that, for the tensile tests in routine testing with fixed gear type tensile testing machines, the straining rate shall be pre-set to give a rate of separation of the grips not greater than 40 % of the test length per minute.

The methods of testing the mass, uniformity and adhesion of the zinc coating shall be those described in sect
33、ion 2 of BS 443:1982. 5.4 Retests 5.4.1 Should any test piece fail any of the specified tests, two additional test pieces shall be taken from the same end of the same package or split package of wire and subjected to the test or tests in which the original test piece failed. 5.4.2 If both additional
34、 test pieces pass the test or tests, the package or split package from which they were taken shall be deemed to comply with the requirements of this standard. If either of the additional test pieces fails, the package or split package shall be deemed not to comply with the requirements of this stand
35、ard. 5.4.3 Where the additional test pieces represent a group of split packages (see 5.2.1), if any test piece fails on retesting to comply with a requirement of this standard, then all the split packages within that group shall be tested. 6 Identification and packaging The wire manufacturer shall a
36、ttach to each package a durable label or labels, on which the following information shall be shown, in addition to such other markings as may be agreed between the wire manufacturer and ropemaker: a) the wire manufacturers name; b) the nominal wire diameter; c) the tensile strength grade of the wire
37、; d) the class of zinc coating (if any) and whether drawn coated or finally coated if class A (see clause 8); e) the number of this British Standard, i.e. BS 27631). NOTEThe type of packing and any other form of protection should be agreed between the wire and the wire rope manufacturers. Section 2.
38、 General purpose rope wire 7 General This section covers wire used in the manufacture of a variety of general purpose ropes. Specific requirements are given for wire of diameters between 0.20 mm and 6.00 mm in tensile strength grades 1370 to 2150, depending upon diameter and grade of wire. The wire
39、may have any one of three types of the following surface finishes: a) bright (without zinc coating); b) class A zinc coat, either drawn after zinc coating (“drawn zinc coated”) or zinc coated after drawing (“finally zinc coated”); c) class Z zinc coat, drawn after zinc coating (“drawn zinc coated”)
40、The wire shall also comply with the requirements of section 1 of this standard. 8 Manufacture 8.1 The wire shall be cold drawn from rod produced from basic carbon steel. The steel shall not be made by the air or air-oxygen bottom blown converter process. The cast analysis shall show not more than 0.
41、050 % of sulphur and not more than 0.050 % of phosphorus. 8.2 The finished wire shall be free from harmful defects. 8.3 For the zinc coated wire the coating shall be applied by either the hot dip or the electrolytic process. If the coating is applied by the hot dip process, the purity of the zinc fe
42、d into the coating bath shall be not lower than grade Zn 3 as specified in BS 3436. NOTEUnless otherwise agreed between the wire manufacturer and the ropemaker, the wire manufacturer has the option to supply a class A coating in the “drawn zinc coated” or “finally zinc coated” condition, provided th
43、at the product is appropriately identified (see item d) of clause 6). 9 Dimensional tolerances The tolerances on the diameter of the wire shall be those given in Table 1. 10 Mechanical properties 10.1 Tensile strength. The minimum tensile strength of the wire shall be the tensile strength grade orde
44、red. NOTETable 2 gives the tensile strength grades generally available. Intermediate tensile strength grades may be supplied by agreement between the wire manufacturer and the ropemaker. The maximum tensile strength shall not exceed the specified minimum by more than the tolerance given in Table 3.
45、For wire intended only for lift ropes in accordance with BS 329, the tensile strength tolerance shall be as given in Table 9, except that the existing nominal diameter range 0.80 mm to 1.00 mm shall be read as 0.40 mm to 1.00 mm. 1) Marking BS 2763 on or in relation to a product is a claim by the ma
46、nufacturer that the product has been manufactured in accordance with the requirements of the standard. The accuracy of such a claim is therefore solely the manufacturers responsibility.
