Full title and description

STB BS IEC 60317-4-2015 — Specifications for particular types of winding wires — Part 4: Solderable polyurethane enamelled round copper wire, class 130. This document is the 2015 edition of the IEC specification for single-coated polyurethane enamel on round copper winding wire intended to be solderable and rated to thermal class 130; it is also published as a national adoption under the designation BS IEC 60317-4:2015.

Abstract

This standard defines physical, electrical and thermal requirements, dimensional tolerances and test methods for solderable polyurethane-enamelled round copper winding wire (class 130). It covers two grading ranges of conductor diameters (grade 1 and grade 2) and includes tests such as solderability, dielectric breakdown, dissipation factor, heat shock, abrasion, solvent resistance, pinhole test and packaging requirements. The standard is intended to be read in conjunction with the IEC 60317‑0‑1 general requirements.

Scope

Specifies requirements for solderable enamelled round copper winding wire of thermal class 130 with a single polyurethane-based coating. The standard covers nominal conductor diameters in two grades (grade 1 from 0.018 mm up to and including 2.000 mm; grade 2 from 0.020 mm up to and including 2.000 mm) and applies test methods and acceptance criteria for mechanical, electrical and thermal performance. It is to be used together with IEC 60317‑0‑1 for general requirements.

Key topics and requirements

• Definition of grades and nominal conductor diameters (grade 1 and grade 2).
• Dimensional tolerances and appearance requirements for enamel coating.
• Electrical resistance and dielectric breakdown requirements.
• Mechanical properties: elongation, springiness, flexibility and adherence.
• Thermal tests: temperature index, heat shock and thermal class 130 requirements.
• Solderability and heat/solvent bonding criteria (acceptance and test methods).
• Resistance tests: abrasion, cut‑through, solvents, transformer oil and refrigerants.
• Dielectric dissipation factor and pinhole testing.
• Continuity of insulation, loss of mass, and packaging/marking requirements.
• Normative references and cross‑reference to IEC 60317‑0‑1 and related IEC series for winding wires.

Typical use and users

Primary users are manufacturers of enameled winding wire, quality and testing laboratories, manufacturers of electric motors, transformers, inductors and other wound electrical apparatus, procurement/specification engineers and regulatory/compliance teams who require uniform material and test criteria for solderable polyurethane-enamelled copper wires. The standard is used to set acceptance criteria for incoming wire batches and to harmonize supplier specifications.

Q: What does it cover?

A: Physical dimensions, electrical and mechanical properties, thermal performance, test methods and acceptance criteria for solderable polyurethane single-coated enamel on round copper wire (two grades of conductor diameter), plus packaging and marking rules; to be used with IEC 60317‑0‑1 general requirements.

Q: Who typically uses it?

A: Wire manufacturers, motor/transformer/inductor producers, test laboratories, procurement engineers and standards/quality managers who specify or verify enameled winding wire for electrical apparatus.

Q: Is it current or superseded?

A: The IEC 2015 edition (4th) is recorded as withdrawn at the IEC webstore with a withdrawal date of 31 December 2021; national adoptions (e.g., BS IEC 60317‑4:2015) may still appear in catalogs or databases but the IEC base publication is listed as withdrawn. Users should check the latest IEC and national standards catalogs for any replacement or consolidated documents before specifying.

Q: Is it part of a series?

A: Yes — it is Part 4 of the IEC 60317 series (Specifications for particular types of winding wires) and is intended to be read together with IEC 60317‑0‑1 (general requirements) and other part- and test-related standards in the IEC 60317 / IEC 60851 family.

Q: What are the key keywords?

A: Solderable polyurethane enamel, round copper wire, class 130, winding wire, enamelled wire, IEC 60317, wire grading, solderability, dielectric tests.
