scope:

This International Standard specifies the requirements of solderable ena- melled round copper winding wire of class 130 with a sole coating based on polyurethane resin, which may be modified provided it remains the chemical identity of the original resin and meets all specified wire requirements. Class 130 is a thermal class that requires a minimum temperature index of 130 and a heat shock temperature of at least 155 °C. The range of nominal conductor diameters covered by this standard is: - Grade 1: 0,018 mm up to and including 2,000 mm, - Grade 2: 0,020 mm up to and including 2,000 mm.
