SIST EN IEC 60317-25:2020/oprA1:2026

SIST EN IEC 60317-25:2020/oprA1:2026 is the Slovenian adoption of Amendment 1 to IEC 60317-25:2020, published by the International Electrotechnical Commission (IEC). It updates the specification for polyester or polyesterimide overcoated with polyamide-imide enamelled round aluminium wire, class 200. For readers working to this product standard, it is the amendment to check alongside the base Part 25 text.

What does SIST EN IEC 60317-25:2020/oprA1:2026 specify?

SIST EN IEC 60317-25:2020/oprA1:2026 specifies an amendment to Part 25 of the IEC 60317 winding-wire series. The document shown updates the product specification for the wire type named in the title and changes one test-related clause.

The page identifies the Slovenian standard as identical to EN IEC 60317-25:2020/prA1:2026. The text shown is organized as the IEC foreword followed by the amendment instruction in Clause 10, Cut-through.

What are the key requirements of SIST EN IEC 60317-25:2020/oprA1:2026?

SIST EN IEC 60317-25:2020/oprA1:2026 makes one clear technical change in the text shown: Clause 10, Cut-through, is replaced with “Test inappropriate”. In practice, users should not apply the cut-through test to this wire type under this amendment.

• Clause 10, Cut-through, is withdrawn and replaced by the statement “Test inappropriate”.

  • This matters because test plans, product acceptance checks, and compliance documents need to follow the updated clause rather than the former test instruction.

• The amendment applies to the Part 25 product defined by the title: polyester or polyesterimide overcoated with polyamide-imide enamelled round aluminium wire, class 200.

  • In practice, the exact wire construction matters when writing purchasing specifications or selecting the correct product standard.

• The foreword states that normative references cited in the publication are indispensable for correct application.

  • This means users should read the amendment together with the base Part 25 document and any referenced publications it relies on.

• The document is prepared under IEC and ISO/IEC drafting rules and is part of IEC technical committee work on winding wires.

  • For organizations commenting on the draft or preparing internal procedures, this shows that the text is still part of a controlled standardization process.
