SPECIFICATIONS FOR PARTICULAR TYPES OF WINDING WIRES –

Part 46: Aromatic polyimide enamelled round copper wire, class 240

1 Scope
This part of IEC 60317 specifies the requirements of enamelled round copper winding wire of
class 240 with a sole coating of aromatic polyimide resin.
The range of nominal conductor diameters covered by this standard is:
– grade 1: 0,020 mm up to and including 2,000 mm;
– grade 2: 0,020 mm up to and including 5,000 mm.
The nominal conductor diameters are specified in Clause 4 of IEC 60317-0-1:2013.
2 Normative reference
The following documents, in whole or in part, are normatively referenced in this document and
are indispensable for its application. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments)
applies.
