It specifics the mechani

20、cal and electrical properties of wires in the diameter range1.25mm to5.00mm. 2 Values for hard-drawn aluminium wire For calculation purposes the following values for hard-drawn aluminium wire shall be used. 3 Material The wires shall be of aluminium of the requisite purity to achieve the mechanical

21、and electrical properties specified hereinafter. The aluminium content shall be not less than99.5%. 4 Freedom from defects The wires shall be smooth and free from all imperfections not consistent with good commercial practice. 5 Diameter and tolerance on diameter The nominal diameter of the wires sh

22、all be expressed in millimetres to two decimal places. Each measurement of wire diameter shall not depart from the nominal diameter by more than the following amounts: For the purpose of checking compliance with the above requirement, the diameter shall be determined by two measurements at right ang

23、les taken at the same cross-section. 6 Length and tolerance on length The nominal length of each coil or reel of wire and the tolerance on length shall be the subject of agreement between manufacturer and purchaser. 7 Joints Joints may be made prior to final drawing. A joint could also be made in th

24、e finished wire, provided that: a) the coil is 500kg or heavier, b) there is not more than one joint in such coils, c) not more than10% of such coils shall contain a joint, d) when requested by the purchaser, the manufacturer shall provide evidence that the joints have a tensile strength of not less

25、 than130MPa. The coils containing a joint made in the finished wire shall be clearly identified. 8 Sampling Samples for the tests specified in Clauses10 and11 shall be taken by the manufacturer from10% of the individual lengths of wire included in any one consignment. Alternatively, or when a qualit

26、y assessment procedure is operated, the sampling rate shall be the subject of agreement between manufacturer and purchaser. 9 Place of testing Unless otherwise agreed between purchaser and manufacturer at the time of ordering, all tests shall be carried out at the manufacturers works. 10 Mechanical

27、tests 10.1 Tensile test One specimen cut from each of the samples taken under Clause8 shall be subjected to a tensile test in accordance with ISO Standard6892. The rate of separation of the jaws of the testing machine shall be not less than25mm/min and not greater than100mm/min. The tensile strength

28、 shall be not less than the appropriate value given inTable 1.

30、 ISO Standard7802. Eight turns shall be wrapped round a mandrel of diameter equal to the wire diameter at a speed not exceeding60rev/min. Six turns shall then be unwrapped and again closely wrapped. The wire shall not break. 11 Resistivity test The electrical resistivity of one specimen cut from eac

31、h of the samples taken under Clause8 shall be determined by the routine method specified in IECPublication468: Method of Measurement of Resistivity of Metallic Materials. The resistivity at20C shall be not greater than28.264 nWm. 12 Certificate of compliance The manufacturer shall, if requested, sup

32、ply the purchaser with a certificate giving the results of all the tests carried out on the samples.
