BS/EN 60317-20-2014 pdf download.Specifications for particular types of winding wires Part 20: Solderable polyurethane enamelled round copper wire, class 155.
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 Of 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.
