8、 which is withdrawn. As a consequence of the detailed review, the scope of the two Parts of BS3592 has been changed. This revision of Part1 combines, with additions and amendments, the requirements of the previous Part1 for round and flat mild steel wire and those of the previous Part2 for carbon st
9、eel round wires of2.0mm diameter and larger. Part2 is now restricted to metallic coated patented cold drawn carbon steel wire, in diameters0.20mm to0.71mm, for the bonded reinforcement of hydraulic hoses. A British Standard does not purport to include all the necessary provisions of a contract. User
10、s of British Standards 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, pagesi andii, pages1 to4, an inside back cover and a back
11、 cover. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on theinside front cover.BS3592-1:1986 BSI 03-1999 1 1 Scope This Part of BS3592 specifies requirements for wire used for rubber hose reinforcement. Two
12、 tensile strength grades are specified for round and flat wires in low carbon steel (mild steel) and five tensile strength grades are specified for round wires in carbon steel, depending upon wire diameter. The round wire diameter range specified is1.60mm to14.22mm and the flat wire dimensions speci
13、fied range from2.18mm 1.63mmto15.9mm 4.76mm. Various types of coating are specified. NOTEThe titles of the publications referred to in this standard are listed on the inside back cover. 2 Manufacture 2.1 Steel rod The rod used for the manufacture of the wire shall be produced from steel made by any
14、process, except the air or air/oxygen bottom blown processes. The rod quality shall be of a grade typical of standard steel making and rod rolling practice. NOTEStandard practice can be taken to mean the following guidelines according to the type of steel. a) Low carbon steel (mild steel). This has
15、an absence of pipe and an inclusion content commensurate with balanced or killed steels of low carbon content. The maximum surface defect depth in the rod should be generally not more than3.5% of the rod diameter. b) Carbon steel. This has an absence of pipe and an inclusion content commensurate wit
16、h killed carbon steels. The maximum depth of partial decarburization and surface defects should be generally not more than3% of the rod diameter. 2.2 Steel composition The ladle analysis of the steel shall show sulphur and phosphorus contents each not greater than0.040%. 2.3 Wire The wire shall be c
17、old drawn or rolled to the finished dimensions. Where appropriate for the tensile strength grade, an inter-process heat treatment shall be applied. The wire shall have one of the following coatings: a) zinc; b) copper; c) bronze; d) copper lacquer; e) phosphate (chemically bonded). NOTE 1There may b
18、e a limit to the wire diameters or sizes available with a zinc, copper or bronze coating. NOTE 2When copper or bronze coatings are specified, the mass of coating and the method of determination of the mass of coating should be the subject of agreement between the purchaser and the manufacturer at th
19、e time of the enquiry and order. 2.4 Welds For the low carbon steel (mild steel) type it shall be permissible for welds made at any stage before inter-process heat treatment to remain in the finished wire. For the carbon steel type, apart from any welds made between rod coils before drawing, there s
20、hall be no welds in any coil of finished wire. 3 Condition of finished wire The wire shall be free from rust and shall not be oiled. The wire in coil shall be “dead cast”, i.e.when a complete turn of wire is removed from the coil without tension and placed on a smooth horizontal surface without rest
21、raint, the wire circle shall have a diameter approximately that of the coil and any corkscrew set, measured by the deviation of one cut end from the horizontal plane, shall not exceed50mm. 4 Properties 4.1 Sizes and tolerances The wire diameters and dimensions of flat wires shall be as given in Tabl
22、e 1 and Table 2 with the appropriate tolerances. NOTE 1The size range varies according to the tensile strength grade. (See Table 3.) NOTE 2If any intermediate sizes are used they should have the tolerance of the next larger listed size.BS3592-1:1986 2 BSI 03-1999 Table 1 Coated round wire diameters
23、and tolerances Table 2 Coated flat wire sizes and tolerances 4.2 Tensile strength The tensile strength shall be calculated on the actual diameter or dimensions of the wire. The tensile strength shall be one of the grades given in Table 3 according to steel type, wire form or size. Table 3 Tensile st
24、rength grades 4.3 Ductility wrap The wire shall withstand without sign of fracture the wrap test appropriate to the tensile strength grades and wire diameters, as given in Table 4. Table 4 Ductility wrap test 4.4 Reverse bend The wire shall withstand without sign of fracture the reverse bend test ov
25、er the bend radius as given in Table 5 according to tensile strength grade and wire size. The wire shall be bent through90 and then in the reverse direction through180. Flat wire shall be tested with the larger dimension parallel to the axis of the bending mandrel. 4.5 Zinc coating 4.5.1 Flat wire.
26、For flat wire, the mass of zinc coating shall be not less than40g/m 2 . 4.5.2 Round wire. For round wire, the mass of zinc coating shall comply with section 3 of BS443:1982, except that where the wires are to be covered with rubber, there shall be only a thin coating of zinc to a minimum mass of one
27、-third of that specified in section 3 of BS443:1982 (rounded to the nearestg/m 2 ).

32、easurements shall be capable of reading to intervals of at least0.002mm. For round wire, pairs of measurements shall be made at right angles to each other at three places along a length of not less than250mm. The reported diameter of the wire shall be the average of the six measurements. For flat wi
33、re, the width and thickness shall be determined by taking three measurements of each dimension along a length of not less than250mm. The separate averages of each group of three measurements shall be the reported dimensions of the wire. 6.2 Mechanical tests Mechanical tests shall be carried out in a
34、ccordance with BS4545. 6.3 Zinc coating The mass of zinc coating shall be determined in accordance with section 2 of BS443:1982. 7 Retests 7.1 If any test piece fails any test, two additional test pieces shall be taken from the same coil of wire and subjected to the test or tests which the original
35、test piece failed. If both additional test pieces pass the test or tests, the coil shall be deemed to comply with this Part of BS3592 but if either of them fails, the coil shall be deemed not to comply. 7.2 If10% or more of the coils in a lot fail to comply, the whole lot shall be deemed not to comp
36、ly with this Part of BS3592. NOTEFurther tests may be carried out by agreement between the purchaser and the manufacturer at the time of the enquiry and order. 8 Documentation, identification and packing 8.1 The manufacturer shall provide for each consignment either: a) a certificate of compliance w
37、ith this Part of BS3592 based on the results of his tests; or b) a test certificate giving the results of all tests identified to each coil number. NOTEWhether type (a) or (b) certificate is to be supplied should be agreed between the purchaser and the manufacturer at the time of the enquiry and ord
38、er. 8.2 Each coil shall be identified with the following information: a) the manufacturers name; b) the number and date of this Part of BS3592, i.e.BS3592-1:1986 1) ; c) the specified, diameter or dimensions and strength; d) the individual coil number; e) the coil mass. NOTEAdditional marking may be
39、 agreed between the purchaser and the manufacturer at the time of the enquiry and order. 8.3 Each coil shall be securely tied and shall have the identification label attached.
