EN 60317-8:2010/prA2:2026 is Amendment 2 to the European specification for polyesterimide enamelled round copper wire, class 180. It updates Part 8 of the winding-wire series, so readers use it together with the base standard for this wire type.

What does EN 60317-8:2010/prA2:2026 specify?

EN 60317-8:2010/prA2:2026 is an amendment to the specification for polyesterimide enamelled round copper wire, class 180. In practice, it changes one clause in the existing Part 8 rather than setting out a complete new product standard.

The document is organized as a foreword plus the amendment text for Clause 20. The amendment revises the clause title and its requirement, so users need to read it together with EN 60317-8:2010.

What are the key requirements of EN 60317-8:2010/prA2:2026?

The substantive change is in Clause 20. EN 60317-8:2010/prA2:2026 replaces the clause title “Resistance to transformer oil” with “Resistance to hydrolysis and to transformer oil”.

Clause 20 also replaces the requirement text with “Test inappropriate.” That is the key practical point: the amended part tells users not to apply a test under this clause for this wire specification.

This means anyone checking conformance for polyesterimide enamelled round copper wire, class 180, should follow the amended wording in Clause 20 rather than the earlier transformer-oil-only heading. For specification, testing, or purchasing, the amendment matters because it changes how the resistance requirement is treated in this part.

The foreword also states that the amendment was prepared by IEC technical committee 55, Winding wires, and that the document is intended to remain unchanged until the stability date shown for it. In practice, that tells readers to use the current approved text and watch for later reconfirmation, withdrawal, or revision.

What terms does EN 60317-8:2010/prA2:2026 define?

• IEC - International Electrotechnical Commission, the international body named in the foreword as the publisher of the related IEC publication.
• CENELEC - the European electrotechnical standards organization referenced in the document’s parallel-voting context.
• CDV - Committee Draft for Vote, the document stage shown on the front matter.
• TC 55 - IEC technical committee 55, identified as Winding wires.
• ISC - “In Some Countries” clauses, the clause type mentioned in the voting note.
• transformer oil - the substance named in Clause 20 before the amendment changes the clause title and requirement.
• hydrolysis - the added subject in the revised Clause 20 title, now paired with transformer oil.

Who uses EN 60317-8:2010/prA2:2026?

EN 60317-8:2010/prA2:2026 is used by organizations working with winding wires, especially polyesterimide enamelled round copper wire, class 180. Typical users include wire manufacturers, electrical equipment makers, test laboratories, and quality or purchasing teams that specify or verify this wire type.

It is also relevant to people involved in electricity transmission and distribution or safety-related work, because the front matter lists those aspects as of interest. For those users, the amendment matters when writing specifications, planning tests, or checking whether a transformer-oil resistance check applies.

What changed in EN 60317-8:2010/prA2:2026 from the previous edition?

EN 60317-8:2010/prA2:2026 is Amendment 2 to IEC 60317-8:2010. The change recorded in the amendment is limited to Clause 20:

• the clause title changes from “Resistance to transformer oil” to “Resistance to hydrolysis and to transformer oil”
• the requirement text is replaced by “Test inappropriate.”

Which standards are used with EN 60317-8:2010/prA2:2026?

The amendment is intended to be used with IEC 60317-8:2010, which is the base Part 8 it updates. The foreword also says the amendment was drafted in accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, Part 2, and developed with the IEC Supplement.

What does the EN 60317-8:2010/prA2:2026 document contain?

The document contains the front matter for the amendment, including IEC foreword statements about publication use, conformity assessment, patents, and the stability date. Its technical content is concentrated in one amendment instruction for Clause 20 of Part 8.

It records the new clause title and the replacement requirement text. That is the part readers use when checking or updating product specifications, test plans, and conformity documentation for this wire type.

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. IEC collaborates closely with the Int
