|ICS Code (Wires):||29.060.10|
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.
