SIST EN 60317-28:2014/oprA2:2026 is a SIST publication of Amendment 2 to the specification for polyesterimide enamelled rectangular copper wire, class 180. It is identical to EN 60317-28:2014/prA2:2026 and sits in the IEC winding wires series, so it is relevant to manufacturers, test laboratories, purchasers, and quality teams working with this wire type. It is a Committee Draft for Vote (CDV), so the text is still under study and subject to change.

What does SIST EN 60317-28:2014/oprA2:2026 specify?

SIST EN 60317-28:2014/oprA2:2026 specifies an amendment to Part 28 of the series on particular types of winding wires. In the text shown, the amendment keeps the focus on polyesterimide enamelled rectangular copper wire, class 180, and updates Clause 20.

The document is organized as IEC foreword material followed by the amendment text itself. The visible technical change is concentrated in one clause, so users updating specifications or test plans only need to check the affected clause rather than a full new part.

What are the key requirements of SIST EN 60317-28:2014/oprA2:2026?

This amendment is narrowly focused. Its main practical effect is to change the treatment of the resistance clause for this winding wire type.

Main technical points

• The product covered remains polyesterimide enamelled rectangular copper wire, class 180. In practice, this amendment applies to the same wire family already identified by Part 28, so it matters when a drawing, purchase specification, or test record cites this exact product type.
• Clause 20 is retitled “Resistance to hydrolysis and to transformer oil”. In practice, any internal document that still names the older clause title should be updated to match the amendment.
• The requirement under Clause 20 is stated as “Test inappropriate.” In practice, this means the amended clause does not call for a normal test result to be reported in the way a routine performance requirement would.
• The amendment replaces the previous title and requirement of Clause 20. In practice, users should check legacy references so that old wording does not remain in quality procedures, inspection plans, or supplier specifications.
• The document is issued as a CDV under IEC/CENELEC parallel voting. In practice, it should be treated as draft text until the voting process is complete.

What terms does SIST EN 60317-28:2014/oprA2:2026 define?

The document uses several standardization terms that matter for understanding its status and technical context.

• IEC - International Electrotechnical Commission, the international body that publishes electrotechnical standards.
• TC 55 - the IEC technical committee responsible for winding wires.
• CDV - Committee Draft for Vote, a draft circulated for national committee voting.
• CENELEC - the European electrotechnical standardization organization involved in parallel voting here.
• class 180 - the thermal class named in the product title, used to identify the wire’s temperature class.
• hydrolysis - chemical breakdown involving water, named in the amended Clause 20.
• transformer oil - the oil referenced in Clause 20 as part of the resistance check.
• amendment - a document that changes an existing standard rather than replacing it in full.

Who uses SIST EN 60317-28:2014/oprA2:2026?

This amendment is used by people who specify, make, test, or buy enamelled winding wire. It is most relevant where rectangular copper wire is used in electrotechnical equipment and where the exact clause wording affects product acceptance.

Typical users include:

• winding wire manufacturers updating product specifications
• test laboratories checking conformity documents and test plans
• quality managers maintaining controlled technical documentation
• buyers and procurement teams writing purchase requirements
• electrical equipment makers that reference the wire in designs or supplier approvals

What changed in SIST EN 60317-28:2014/oprA2:2026 from the previous edition?

SIST EN 60317-28:2014/oprA2:2026 is Amendment 2 to IEC 60317-28:2013. The change stated in the document is the revision of Clause 20, which is retitled “Resistance to hydrolysis and to transformer oil” and marked “Test inappropriate.”

Which standards are used with SIST EN 60317-28:2014/oprA2:2026?

• IEC 60317-28:2013 - the base document that this amendment updates.
• EN 60317-28:2014/prA2:2026 - the European parallel-voting version identified as identical to the SIST publication.
• ISO/IEC Directives, Part 1 and Part 2 - the drafting framework named in the foreword for preparing the amendment.
• IEC Supplement - the IEC drafting supplement cited with the Directives.

What does the SIST EN 60317-28:2014/oprA2:2026 document contain?

The document contains the IEC foreword, publication and voting notes, patent-rights guidance, and a stability-date note. Its technical content shown here is a single amendment clause that changes Clause 20 for this wire type.

It is a short amendment document rather than a full reissue of the winding-wire specification. For users, that means the main task is to apply the Clause 20 change correctly in specifications, testing records, and product files.

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.
