• Effective Date: 16-Jun-2026

SIST EN IEC 60317-27-4:2020/oprA2:2026 is Amendment 2 to the IEC specification for paper tape covered rectangular aluminium wire. It updates the product standard for this winding wire type, with changes to the hydrolysis and transformer oil clause and to packaging labelling. The document is used by manufacturers, suppliers, and users who need to identify, package, or specify this wire consistently.

What does SIST EN IEC 60317-27-4:2020/oprA2:2026 specify?

SIST EN IEC 60317-27-4:2020/oprA2:2026 specifies amendments to Part 27-4 of the winding wires series. The amendment is organized around the foreword and two technical changes, one in Clause 20 and one in Clause 30.

Clause	What it covers in this amendment
Clause 20	Resistance to hydrolysis and to transformer oil
Clause 30	Packaging

In practice, this means the document does not restate the whole product specification. It tells readers exactly what to change in the parent standard for this wire type.

What are the key requirements of SIST EN IEC 60317-27-4:2020/oprA2:2026?

The amendment has two main technical effects: it replaces the test statement in Clause 20 and adds a packaging label rule in Clause 30. These changes affect how the wire is assessed and how packaged product is identified.

• Clause 20 - Resistance to hydrolysis and to transformer oil is replaced with the statement “Test inappropriate.” In practice, users should not plan this test for the wire under this amendment.
• Clause 30 - Packaging adds a label requirement for each packaging unit. This makes traceability part of normal packing and shipping.
• The label content must be agreed between supplier and user. In practice, the label format can be adapted to the purchase agreement, but the listed items still have to be included.
• The label shall include the manufacturer's name and/or trade mark. This helps identify who made the wire if questions arise later.
• The label shall include the type of wire and paper, for example a trade name and/or an IEC specification number. This helps match the package to the ordered product.
• The label shall include the net mass of wire. This supports receiving checks, stock control, and logistics.
• The label shall include the nominal conductor diameter of wire and number of layers of paper. This is important for checking that the build matches the intended design.
• The label shall include the date of manufacture. This supports traceability and stock rotation.

What terms does SIST EN IEC 60317-27-4:2020/oprA2:2026 define?

• IEC - International Electrotechnical Commission, the organization that publishes the amendment.
• CENELEC - the European electrotechnical standardization body whose members take part in the parallel voting process mentioned in the foreword.
• TC 55 - the IEC technical committee for Winding wires, which prepared the amendment.
• CDV - Committee Draft for Vote, the draft stage identified on the document.
• Amendment 2 - the second change document for the 2020 edition of Part 27-4.
• Parallel voting - the IEC/CENELEC voting process used for this draft.
• Stability date - the date after which the committee may reconfirm, withdraw, or revise the document.

Who uses SIST EN IEC 60317-27-4:2020/oprA2:2026?

SIST EN IEC 60317-27-4:2020/oprA2:2026 is used by manufacturers, suppliers, and users of winding wires in the electrical and electronic fields. It matters to people who specify paper tape covered rectangular aluminium wire and to those who check packaging identity and traceability.

It is also relevant to IEC and CENELEC committee members during the voting and adoption process. In practice, buyers, quality teams, and production engineers use the packaging information to reduce mix-ups and to support incoming inspection.

What changed in SIST EN IEC 60317-27-4:2020/oprA2:2026 from the previous edition?

SIST EN IEC 60317-27-4:2020/oprA2:2026 is Amendment 2 to IEC 60317-27-4:2020. The amendment makes two stated changes:

• Clause 20 is replaced with “Test inappropriate.”
• Clause 30 gains new packaging label requirements for each packaging unit.

Which standards are used with SIST EN IEC 60317-27-4:2020/oprA2:2026?

• IEC 60317-27-4:2020 - the parent document that this amendment updates.
• ISO/IEC Directives, Part 1 - the procedural rules used when preparing the amendment.
• ISO/IEC Directives, Part 2 - the drafting rules used for the document structure and wording.
• IEC Supplement - additional IEC drafting guidance used together with the directives.

What does the SIST EN IEC 60317-27-4:2020/oprA2:2026 document contain?

This document contains the amendment text for Part 27-4, including a foreword and the exact instructions for changing the parent standard. The technical content is concentrated in the replacement of Clause 20 and the added packaging text in Clause 30.

It is a change document rather than a full restatement of the product standard. Readers use it to update specifications, revise labels, and align purchasing or quality records with the amended wording.

9 FOREWORD
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 International Organization for
18 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
