NOTE 1 As for the actual or nominal wire diameter not given in this table, the value of the nearest larger wire diameter in this table shall be applied. NOTE 2 As for the wire marked with bar (-) in this table, it indicates that the mechanical properties are not be specified. As for the wires marked with slush (/),there is no preseription herein since no wires in such range are produced.
The general and commonly used specifications can be obtained in a quick and economical way, whereas custom-made products are not the case.
