EN IEC 60317-25:2020/prA1:2026 is a CLC amendment to IEC 60317-25:2020 for polyester or polyesterimide overcoated with polyamide-imide enamelled round aluminium wire, class 200. It is the document to use when you need the amended technical text for this winding-wire type in standardization, testing, buying, or quality work. The amendment changes the treatment of the cut-through clause.

What does EN IEC 60317-25:2020/prA1:2026 specify?

EN IEC 60317-25:2020/prA1:2026 specifies an amendment to the Part 25 winding-wire standard for a specific enamelled round aluminium wire construction and class. The shown technical change is in Clause 10, Cut-through, which is replaced by amended text.

The document is organized as front matter and the amendment text for the affected clause. The main practical point is that users should read this amendment together with the base part it updates.

Clause	What it covers
Clause 10	Cut-through

What are the key requirements of EN IEC 60317-25:2020/prA1:2026?

The amendment has one clear technical effect: it changes how Clause 10 treats cut-through for this wire type. In practice, that matters because test plans, product specifications, and inspection records need to follow the amended clause rather than the earlier one.

• Clause 10, Cut-through, is replaced. The amended text states that the test is inappropriate for this product type. For users, that means cut-through should not be scheduled or used as a compliance test under this amendment.
• The scope is the specific class 200 wire named in the title. The amendment applies to polyester or polyesterimide overcoated with polyamide-imide enamelled round aluminium wire. This helps buyers and laboratories match the document to the correct product build.
• The document is an amendment, not a full standalone specification. It updates the base Part 25 text rather than repeating all product requirements. In practice, the base standard still provides the main specification context.
• The affected topic is a test method, not a geometry or material change. The only shown technical change concerns cut-through. That means the impact is on qualification and verification work more than on manufacture details.
• The document is part of IEC 60317 work for winding wires. It belongs to the series for particular types of winding wires. Users in procurement and quality can use that family name to align part numbers and acceptance documents.

What terms does EN IEC 60317-25:2020/prA1:2026 define?

• Winding wires - Insulated wires used for winding applications, especially in electrical equipment.
• Enamelled round aluminium wire - A round aluminium conductor with an enamel insulation coating.
• Polyester - One of the base overcoat materials named in the title.
• Polyesterimide - The alternative base overcoat material named in the title.
• Polyamide-imide - The outer enamel layer named in the title.
• Class 200 - The class designation used in the title for this wire type.
• Cut-through - The test topic covered by Clause 10 and replaced by the amendment text.

Who uses EN IEC 60317-25:2026/prA1:2026?

EN IEC 60317-25:2020/prA1:2026 is used by people who specify, make, test, or buy this winding-wire type. It is also used by committees handling IEC/CENELEC voting and publication work.

Typical users include:

• winding-wire manufacturers and suppliers
• test laboratories and quality teams
• buyers and technical specifiers for electrical wire products
• IEC National Committees and CENELEC members working on the vote
• TC 55 participants responsible for winding wires

What changed in EN IEC 60317-25:2020/prA1:2026 from the previous edition?

EN IEC 60317-25:2020/prA1:2026 is an amendment to IEC 60317-25:2020. The stated change is in Clause 10, where the cut-through text is replaced and the test is marked inappropriate.

Which standards are used with EN IEC 60317-25:2020/prA1:2026?

• IEC 60317-25:2020 - The base Part 25 specification that this amendment updates and must be read with.

What does the EN IEC 60317-25:2020/prA1:2026 document contain?

The document contains IEC front matter, the committee and voting information, and the amendment text for the affected clause. It also includes publication notes on parallel voting, patent rights, and stability date. The technical content shown is the replacement of Clause 10, Cut-through. For users, that means the document is mainly for updating existing specifications and test plans rather than introducing a full new product standard.
