10、gency issue. In view of its general and continuing use this revision has been prepared. The standard is now technically updated and metricated and details of dimensional tolerances have been revised in keeping with current manufacturing practices. Provision is now made for three conditions of supply
11、 and five different conditions of finish. BS 1052:1942 is withdrawn on publication of this revision. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard
12、 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, pages1 to4, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated.
13、This will be indicated in the amendment table on the inside front cover.BS1052:1980 BSI 07-1999 1 Section 1.

16、atment before final hard drawing or rolling. 3.4 coil one length of wire in close-packed concentric rings 3.5 length a straight piece of wire cut to a specified length 3.6 bundle two or more coils bound together or a number of lengths bound together 3.7 consignment any quantity of finished wire in c
17、oils or lengths delivered at one time 4 Information to be supplied by the purchaser The following information shall be given on the enquiry or order: a) the number of this British Standard, i.e.BS1052; b) the product form (coils or lengths) (seeclause3); c) the diameter or characteristic dimensions
18、of the wire; d) the quantity; e) whether the wire is required to be welded (seeclause6); f) the condition of supply (seeclause7); g) the finish (seeclause8); h) any requirements for special protection (seeclause13); i) the tensile strength range, or, in the case of hard drawn or rolled wire of up to
19、1.25mm diameter or equivalent cross-sectional area, the minimum tensile strength (seeclause15); j) any additional requirements, e.g. for packaging. An example of this information to be supplied by the purchaser is: BS 1052, coils, 2.5mm diameter wire,500kg, mild drawn, bright, 340N/mm 2to500N/mm 2 .
20、 5 General The wire shall comply with the requirements of section 1 and the specific requirements of section 2. 6 Quality of wire 6.1 Chemical analysis. The sulphur and phosphorus contents of the wire shall be each not greater than0.05% by cast analysis. If the wire is required to be welded, the car
21、bon content shall be not greater than0.18% and the manganese content shall be not less than10times the sulphur content of the cast, nor greater than1.00%. 6.2 Defects.The finished wire shall be free from defects harmful to its end use. 7 Condition of supply The wire shall be supplied in one of the f
22、ollowing conditions specified by the purchaser: a) finally annealed; b) mild drawn or rolled; c) hard drawn or rolled. 8 Finish The wire shall be supplied with one of the following finishes specified by the purchaser: a) a finish produced by final annealing: to be agreed with the manufacturer; b) br
23、ight; c) galvanized;BS1052:1980 2 BSI 07-1999 d) coppered; e) tinned. NOTEWire may be supplied with other finishes if agreed at the time of enquiry and order. 9 Coating 9.1 Galvanized round wire. The galvanized coating on round wire shall comply with all of the requirements of BS443, except that low
24、er coating weights and dips may be agreed between the purchaser and the manufacturer depending upon the purpose for which the wire is required. 9.2 Galvanized sections other than round. Requirements for the galvanized coating on sections other than round shall be agreed between the purchaser and the
25、 manufacturer. 9.3 Coatings other than galvanized. Requirements for coatings other than galvanized shall be agreed between the purchaser and the manufacturer. 10 Selection of test pieces 10.1 A test piece of sufficient length to enable the relevant tests specified in section 2 of this standard to be
26、 carried out shall be selected in accordance with10.2 from the wire in the condition in which it will be supplied to the purchaser. Apart from straightening the test lengths before testing, they shall not be treated in any way that would make them unrepresentative of the wire. 10.2 One test piece sh
27、all be taken from every ten or part of ten coils or bundles of lengths, if the mass of each coil or bundle of lengths is50kg or greater, subject to a rate of not less than one test piece per1000kg. Two test pieces shall be taken from every1 000kg or part of1 000kg, if the individual masses of coils
28、or bundles or lengths are each less than50kg. 11 Method of testing 11.1 Round wire. The procedures for mechanical testing of round wire shall be in accordance with the requirements of BS4545. 11.2 Wire of section other than round. The procedures for mechanical testing of wire of section other than r
29、ound shall be in accordance with the requirements of BS4545. If a ductility test is to be carried out, the method of testing shall be agreed by the purchaser and the manufacturer. 11.3 Straining rate. For fixed-gear tensile-testing machines, the straining rate shall be preset to give a rate of separ
30、ation of the grips of not less than25% and not greater than50% of the test length per minute. 12 Retests 12.1 If any test piece fails any of the tests specified in section 2, additional test pieces shall be taken and retested. For wire supplied in coil form, one additional test piece shall be taken
31、from each end of the same coil. Part of the coil may be discarded before taking the new test pieces. If the manufacturer wishes to withdraw that coil, the two test pieces shall be taken from another coil in the same consignment. For wire supplied in lengths, four additional test pieces shall be take
32、n from randomly chosen lengths in the same consignment. 12.2 If all the additional test pieces pass all the tests, the consignment shall be deemed to comply with the requirements of this standard. If any of the additional test pieces fails any of the tests, the consignment shall be deemed not to com
33、ply with the requirements of this standard. 13 Packaging and marking Consignments of wire shall be suitably protected against corrosion during transportation. If special protection is required it shall be agreed at the time of enquiry and order. Wire supplied in coils, bundles of coils or bundles of
34、 lengths shall be securely tied and shall carry a suitable label or labels on which shall be marked: a) the manufacturers name; b) the number of this British Standard, i.e. BS 1052; NOTEMarking BS1052 on or in relation to a product is a claim by the manufacturer that the product has been manufacture
35、d in accordance with the requirements of the standard. The accuracy of such a claim is therefore the manufacturers sole responsibility. c) the diameter or characteristic dimension of the wire; d) the condition of supply; e) the finish; f) the nominal tensile strength. If additional markings are requ
36、ired they shall be agreed between the purchaser and the manufacturer.BS1052:1980 BSI 07-1999 3 Section 2.

For galvanized round wire, the diameter of the wire shall be within the relevant tolerance specified inTable 2. 14.2 Wire of section other than round. For wire of section other than round, the tolerance(s) on dime
38、nsions shall be agreed between the purchaser and manufacturer. 15 Tensile strength 15.1 With the exception of hard drawn or rolled wire of up to and including1.25mm diameter or equivalent cross-sectional area, the purchaser shall specify, for the relevant condition of supply, the required range of t
39、ensile strength within the limits given inTable 3. The difference between the minimum and maximum value of the range specified by the purchaser shall be160N/mm 2 . 15.2 For hard drawn or rolled wire of up to and including1.25mm diameter or equivalent cross-sectional area, only the required minimum t
40、ensile strength shall be specified by the purchaser. 16 Ductility test 16.1 Round wire 16.1.1 Wrapping test on round wire. The wrapping test shall be applied to round wire of up to and including4.75mm diameter. The wire shall not break nor show defects that could lead to subsequent failure when eigh
41、t complete turns of the wire are close-coiled around a mandrel of diameter equal to that of the wire. 16.1.2 Bend test on round wire. The bend test shall be applied to round wire of greater than4.75mm diameter. The wire shall not crack or fracture when bent through90 around a mandrel of diameter equ
42、al to that of the wire. During the test, the wire shall be free to move longitudinally in the forming device. 16.3 Wire of section other than round. The requirements for a ductility test on wire of section other than round shall be agreed between the purchaser and the manufacturer. Table 1 Tolerance
