DIN EN 60317-21:2014-10

This part of IEC 60317 forms an element of a series of standards which deals with insulated wires used for windings in electrical equipment. This series consists of three groups describing: 1) Winding wires - Test methods (IEC 60851); 2) Specifications for particular types of winding wires (IEC 60317); 3) Packaging of winding wires (IEC 60264). This part of IEC 60317 specifies the requirements for solderable polyurethane enamelled round copper wire, class 155, with dual coating. The base coating is a layer based on polyurethane resin, which may be modified providing it retains its chemical basis and meets all technical specifications. The top coating is based on polyamide resin. The range of nominal conductor dimensions covered by this standard is: - grade 1: 0,050 mm up to and including 1,600 mm; - grade 2: 0,050 mm up to and including 1,600 mm. The responsible committee is DKE/K 413 "Wickeldrähte" ("Winding wires") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
