This part of IEC 60317 specifies the requirements of solderable enamelled round copper winding wire of class 155 with a sole coating based on polyurethane resin@ which may be modified providing it retains the chemical identity of the original resin and meets all specified wire requirements. 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. The range of nominal conductor diameters covered by this standard is: -Grade 1: 0@018 mm up to and including 0@800 mm; - Grade 2: 0@020 mm up to and including 0@800 mm. The nominal conductor diameters are specified in Clause 4 of IEC 60317-0-1:2013.
