This International Standard specifies the requirements of enamelled round copper winding wire of class 200 with a dual coating. The coating may be modified provided it remains the chemical identity of the original resin and meets all specified wire requirements. Class 200 is a thermal class that requires a minimum temperature index of 200 and a heat shock temperature of at least 220 °C. The range of nominal conductor diameters covered by this standard is: - Grade 1: 0,050 mm up to and including 2,000 mm; - Grade 2: 0,050 mm up to and including 5,000 mm.
