This International Standard specifies the requirements of enamelled round copper winding wire of class 180 with a sole coating based on polyesterimide resin, which may be modified provided it remains the chemical identity of the original resin and meets all specified wire requirements. 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 range of nominal conductor diameters covered by this standard is Grade 1: 0,018 mm up to and incl. 3.150 mm; Gr.2: 0,020 mm to 5,000 mm; Gr.3: 0,250 mm to 1,600 mm.
