Specifications for particular types of winding wires - Part 12: Polyvinyl acetal enamelled round copper wire, class 120 (IEC 60317-12:2020)

IEC 60317-12:2020 is available as IEC 60317-12:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60317-12:2020 specifies the requirements of enamelled round copper winding wires of class 120 with a sole coating based on polyvinyl acetal or polyvinyl formal resin, which can be modified provided it retains the chemical identity of the original resin and meets all specified wire requirements.
NOTE 1 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.
NOTE 2 Polyvinyl acetal is a general name for a family of thermoplastic vinyl resins produced by the condensation of polyvinyl alcohol with an aldehyde. Examples are polyvinyl acetal, polyvinyl formal and polyvinyl butyral. The range of nominal conductor diameters covered by this document is:
- Grade 1: 0,040 mm up to and including 2,500 mm;
- Grade 2: 0,040 mm up to and including 5,000 mm;
- Grade 3: 0,080 mm up to and including 5,000 mm.
The nominal conductor diameters are specified in Clause 4 of IEC 60317-0-1:2013. This fourth edition of IEC 60317-12 cancels and replaces the third edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- modification of the Scope;
- addition of reference to transformer oil resistance test method in Clause 20.

Overview

EN IEC 60317-12:2020 (CLC adoption of IEC 60317-12:2020) defines the specifications for polyvinyl acetal enamelled round copper wire, class 120 used as winding wire. This fourth edition replaces the 2010 edition and is published as an RLV (Redline version) that includes the international standard plus a redline record of technical changes. The standard covers material identity (polyvinyl acetal/polyvinyl formal family), allowable resin modifications, and the dimensional ranges for nominal conductor diameters across three grades.

Key topics and technical requirements

EN IEC 60317-12:2020 sets out requirements and referenced test methods for essential winding-wire properties. Major technical topics include:

• Material and coating: Sole coating based on polyvinyl acetal or polyvinyl formal resins; modified resins are permitted if chemical identity is retained and all wire requirements are met.
• Nominal conductor diameters (grades):
  • Grade 1: 0.040 mm to 2.500 mm
  • Grade 2: 0.040 mm to 5.000 mm
  • Grade 3: 0.080 mm to 5.000 mm
• Electrical and mechanical properties: dimensions, electrical resistance, elongation, springiness, flexibility and adherence.
• Thermal and durability tests: heat shock, heat/solvent bonding, temperature index and related evaluations for class 120 insulation.
• Insulation integrity and aging: breakdown voltage, continuity of insulation, pin-hole testing, loss of mass.
• Environmental and chemical resistance: resistance to solvents, refrigerants, transformer oil (newly referenced test method added in this edition), and abrasion.
• Processability: solderability, cut-through resistance, dielectric dissipation factor and other production-relevant tests.
• Packaging and documentation: requirements for marking and packaging consistent with winding-wire handling and storage.

Applications and who uses this standard

EN IEC 60317-12:2020 is relevant to manufacturers, designers and specifiers of electrical windings where polyvinyl acetal enamelled copper wire is used. Typical users include:

• Winding wire manufacturers and quality laboratories (production control and type testing)
• Motor, transformer and inductor manufacturers (material selection and procurement specifications)
• Electrical appliance and electromechanical equipment designers specifying insulation class and performance
• Test houses and conformity assessment bodies verifying compliance with IEC/CENELEC requirements

The standard helps ensure consistent performance, manufacturability and interchangeability of enamelled round copper winding wires intended for class 120 insulation systems.
