Specifications for particular types of winding wires - Solderable polyurethane enamelled round copper wire overcoated with polyamide, class 180 Ingestion-build-48183 b) Residue on ignition is1 Scope This part of IEC 60317 specifies the requirements of solderable enamelled round copper winding wire of class 180 with a dual coating. The underlying coating is based on polyurethane resin, which may be modified providing it retains the chemical identity of the original resin and meets all specified wire requirements. The superimposed coating is based on polyamide resin. NOTE A modified resin is a resin that has undergone a chemical change, or
