For definitions, general notes on methods
23、 of test and the complete series of methods of test for winding wires, see IEC 60851-1. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition o
24、f the referenced document (including any amendments) applies. IEC 60851-1, Winding wires Test methods Part 1: General IEC 60851-5:2008, Winding wires Test methods Part 5: Electrical properties 3 Test 4: Dimensions 3.1 Equipment 3.1.1 Round and rectangular wire The equipment used shall have a resolut
25、ion of 2 m or less for wires over 0,200 mm and for wires up to and including 0,200 mm, a resolution of 1 m or less. Both mechanical contact and optical non-contact micrometers may be used. If mechanical contact micrometers are used, the ratio of measuring force and anvil diameter shall be in accorda
26、nce with the range as given in Table 1a and Table 1b. The diameter range of the spindle and anvil is also given in Table 1a and Table 1b. If optical micrometers are used, the average of the readings shall be recorded as the diameter of the conductor. If a specific measuring equipment must be used, i
27、t shall be agreed upon between the customer and the supplier.

28、,01 P 0,16 0,16 0,063 mm Resistance Dimension 3 of IEC 60851-5 3.2.1.1 NOTE By agreement between purchaser and supplier, resistance measurements may be made in the range of nominal conductor diameters over 0,063 mm and up to and including 1,000 mm. 3.2.5.2 Rectangular wire On a straight piece of wir
29、e at each of three places at least 100 mm apart, one measurement shall be made of the two dimensions of the wire. Where the dimension of the specimen is greater than the diameter of the micrometer spindle, measurements shall be made both at the centre of the face of the specimen and over the edges.
30、If these values differ, only the highest value shall be noted. The three single values shall be reported for each dimension of the wire. The mean values represent the overall width or the overall thickness respectively. 3.2.5.3 Bunched wire NOTE The method indicated below gives useful values in prac
31、tice, but not an accurate overall diameter. The overall diameter is the width of a layer wound on a mandrel divided by the number of turns. The bunched wire shall be wound closely on a mandrel according to Figure 1 and under a tension in newtons, which is 65 times the total nominal cross-section of
32、the conductors in square millimetres. The width of the layer shall be not less than 10 mm for bunched wires with overall diameters up to and including 0,5 mm, and be not less than 20 mm for larger diameters and shall be measured with a precision of 0,5 mm. One measurement shall be made. The overall
33、diameter rounded off to 0,01 mm shall be reported. 3.2.6 Increase in diameter due to the bonding layer of enamelled round wire The increase in diameter due to the bonding layer is the difference of the overall diameter with and without the bonding layer. The overall diameter of the wire shall be mea
34、sured according to 3.2.5.1. After removal of the bonding layer by means of a solvent or any other suitable agent or by any other method which does not damage the underlying coating, the measurement shall be repeated. The difference of the two mean values shall be reported as the increase in diameter
35、 due to the bonding layer.
