EN 60317-28:2014/prA2:2026 is a CLC amendment to the winding-wire specification for polyesterimide enamelled rectangular copper wire, class 180. It updates Part 28 of the EN 60317 series for manufacturers, test laboratories, and specifiers who work with this wire type.

What does EN 60317-28:2014/prA2:2026 specify?

EN 60317-28:2014/prA2:2026 specifies an amendment to the existing Part 28 specification for polyesterimide enamelled rectangular copper wire, class 180. In practice, it changes one technical clause in the base document rather than redefining the whole wire family.

The amendment is organized as front matter, a foreword, and the amendment text. The technical change shown is in Clause 20.

What are the key requirements of EN 60317-28:2014/prA2:2026?

EN 60317-28:2014/prA2:2026 changes how Clause 20 is presented and applied. The practical effect is limited, but it matters because users must cite and test against the amended wording.

• The document applies to polyesterimide enamelled rectangular copper wire, class 180. That tells users which wire family and thermal class the amendment belongs to.
• Clause 20 is retitled “Resistance to hydrolysis and to transformer oil”. This makes the subject of the clause explicit for test plans and product descriptions.
• The replacement requirement for Clause 20 is “Test inappropriate.” In practice, users should not treat this clause as a normal test requirement in this amendment.
• The amendment is tied to the underlying Part 28 specification in IEC 60317-28:2013. That means it is meant to be read with the base wire specification, not as a standalone product standard.
• The document is prepared under IEC TC 55, Winding wires. For readers, that shows the technical committee responsible for the wire series.
• The page notes IEC/CENELEC parallel voting and a stability date. For users, that means the text is part of the formal standards process and can still be revised before it is finalized.

For a buyer or quality manager, the main point is simple: if your specification or inspection plan cites Clause 20, update the wording to match this amendment.

What terms does EN 60317-28:2014/prA2:2026 define?

• Winding wires - insulated conductors used to make coils in electrical equipment.
• Rectangular copper wire - a copper conductor with a rectangular cross-section, used where packing density and space use matter.
• Polyesterimide enamelled - coated with polyesterimide enamel insulation, which is the insulation system named in the title.
• Class 180 - the thermal class identified in the title; it tells users the wire’s temperature class designation.
• Hydrolysis - chemical breakdown caused by reaction with water, which is relevant to the amended Clause 20.
• Transformer oil - insulating oil used in transformers; the clause names it as part of the amended resistance check.
• International Electrotechnical Commission (IEC) - the international body named in the foreword as the publisher of the publication.
• Committee Draft for Vote (CDV) - the IEC ballot stage shown on the page for this amendment.

Who uses EN 60317-28:2014/prA2:2026?

EN 60317-28:2014/prA2:2026 is used by winding-wire manufacturers, transformer and other electrotechnical equipment designers, test laboratories, quality managers, and procurement teams. They use it to specify the wire type, update test documents, and check that product descriptions match the amended clause wording.

It is also relevant to conformity assessment bodies and standards committees working in electricity transmission and distribution and safety-related electrotechnical applications.

What changed in EN 60317-28:2014/prA2:2026 from the previous edition?

EN 60317-28:2014/prA2:2026 is Amendment 2 to IEC 60317-28:2013. The change shown replaces Clause 20: the title becomes “Resistance to hydrolysis and to transformer oil” and the replacement requirement reads “Test inappropriate.”

Which standards are used with EN 60317-28:2014/prA2:2026?

• IEC 60317-28:2013 - the base Part 28 specification that this amendment updates and must be read with.

What does the EN 60317-28:2014/prA2:2026 document contain?

EN 60317-28:2014/prA2:2026 contains the foreword, the amendment text, and the administrative information that accompanies this IEC draft. The substantive technical content shown is the revision of Clause 20 on resistance to hydrolysis and transformer oil.

It is a short amendment document rather than a full reissue of the winding-wire specification. For implementation work, the important task is to carry the amended Clause 20 wording into specifications, verification plans, and internal quality documents.

10 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
11 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
12 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
13 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
14 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
15 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
16 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
17 with the IEC also participate in this preparation.
