SIST EN IEC 60317-27-1:2020/oprA2:2026 is the Slovenian adoption of IEC Amendment 2 to IEC 60317-27-1:2020, published by SIST. It updates the specification for paper tape covered round copper wire, a type of winding wire used in electrotechnical applications, and it is relevant to manufacturers, testers, specifiers, and buyers of this wire. The amendment shown here mainly changes Clause 20 on resistance to hydrolysis and transformer oil.
What does SIST EN IEC 60317-27-1:2020/oprA2:2026 specify?
SIST EN IEC 60317-27-1:2020/oprA2:2026 is an amendment to the base part for paper tape covered round copper wire. The page identifies it as identical with EN IEC 60317-27-1:2020/prA2:2026.
The visible text is limited to the amendment foreword and the replacement instruction for Clause 20. In practice, this means the document is used together with the 2020 base specification, not as a stand-alone product standard.
What are the key requirements of SIST EN IEC 60317-27-1:2020/oprA2:2026?
The main technical change in SIST EN IEC 60317-27-1:2020/oprA2:2026 is in Clause 20. The clause for resistance to hydrolysis and to transformer oil is replaced so that the test is not applied to this wire type.
That matters because users should not plan, perform, or report this test as a requirement for paper tape covered round copper wire under this amendment. For a manufacturer or test lab, the practical effect is to avoid running an unnecessary test method for this product.
The amendment does not restate the full product specification. It works as a targeted change to the base document, so the underlying requirements remain in IEC 60317-27-1:2020 and this amendment only changes the clause named here.
The foreword also places the document in the IEC publication system and notes that it is part of the IEC-CENELEC parallel voting process. For users, that is a signal that the text is a formal draft-stage amendment and should be read as part of the standards-development process.
What terms does SIST EN IEC 60317-27-1:2020/oprA2:2026 define?
- winding wires - conductors used to make windings in electrical equipment.
- paper tape covered round copper wire - a round copper conductor covered with paper tape.
- resistance to hydrolysis and to transformer oil - a test concerned with how the covering behaves against moisture-related chemical action and transformer oil.
- Committee Draft for Vote (CDV) - an IEC draft circulated for voting by national committees.
- parallel voting - IEC and CENELEC voting carried out together on the same draft.
Who uses SIST EN IEC 60317-27-1:2020/oprA2:2026?
SIST EN IEC 60317-27-1:2020/oprA2:2026 is used by people who specify, manufacture, test, or purchase winding wire. That includes wire producers, electrical equipment manufacturers, test laboratories, quality teams, and buyers who need a clear product requirement for paper tape covered round copper wire.
It is also relevant to standards and conformity-assessment work in the electrotechnical field. The foreword notes the role of IEC National Committees, CENELEC members, and independent certification bodies in the standards process.
What changed in SIST EN IEC 60317-27-1:2020/oprA2:2026 from the previous edition?
SIST EN IEC 60317-27-1:2020/oprA2:2026 is Amendment 2 to IEC 60317-27-1:2020. The change shown in the text is the replacement of Clause 20.
Which standards are used with SIST EN IEC 60317-27-1:2020/oprA2:2026?
| Standard | Contribution |
|---|---|
| IEC 60317-27-1:2020 | Base specification for paper tape covered round copper wire, which this amendment updates. |
| EN IEC 60317-27-1:2020/prA2:2026 | The corresponding European designation stated on the page for the same amendment. |
What does the SIST EN IEC 60317-27-1:2020/oprA2:2026 document contain?
The document contains a short foreword and a single technical amendment instruction. The foreword gives IEC publication notes, voting information, patent guidance, and the stability-date process note.
The technical body shown is a direct replacement for Clause 20. It is a textual amendment rather than a method chapter with tables, figures, formulas, or worked examples.
For readers, that means the document is mainly a change notice to an existing wire specification. For test labs and quality teams, the most important task is to apply the Clause 20 replacement when using the base standard.
