IEC 60317-19 pdf download.Specifications for particular types of winding wires
This International Standard specifies the requirements of solderable enamelled round copper winding wire of class 1 30 with a dual coating. The underlying coating is based on polyurethane resin, which may be modified providing it retains the chemical identity of the original resin and meets all specified wire requirements. The superimposed coating is based on polyamide resin. 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 1 30 is a thermal class that requires a minimum temperature index of 1 30 and a heat shock temperature of at least 1 55 °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 : 0,050 mm up to and including 1 ,600 mm; Grade 2: 0,050 mm up to and including 2,000 mm. The nominal conductor diameters are specified in clause 4 of IEC 6031 7-0-1 .
