IEC 60317-23 pdf download.Specifications for particular types of winding wires
This International Standard specifies the requirements of solderable enamelled round copper winding wire of class 180 with a sole coating based on polyesterimide resin, which may be modified providing it retains the chemical identity of the original resin and meet all specified wire requirements. NOTE A modified resin is a resin that has undergone a chemical change, or contains one or more additives to enhance certain performance or application characteristics. Class 180 is a thermal class that requires a minimum temperature index of 180 and a heat shock temperature of at least 200 °C. The temperature in degrees Celsius corresponding to the temperature index is not necessarily that at which it is recommended that the wire be operated and this will depend on many factors, including the type of equipment involved. The range of nominal conductor diameters covered by this standard is: – Grade 1: 0,020 mm up to and including 1,600 mm; – Grade 2: 0,020 mm up to and including 1,600 mm. The nominal conductor diameters are specified in clause 4 of IEC 60317-0-1.
