This International Standard specifies the requirements of enamelled round aluminium winding wire of class 180 with a sole coating based on polyester-imide 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: 0,400 mm up to and including 1,600 mm; - Grade 2: 0,400 mm up to and including 5,000 mm.
