Overview

SIST EN 60317-8:2010/oprA2:2026 is an amendment to a key European standard focused on winding wires, specifically addressing polyesterimide enamelled round copper wire, class 180. Developed by the CLC and under the stewardship of IEC technical committee 55, this amendment is part of an ongoing effort to ensure harmonization and quality in the use and specification of winding wires in electrical and electronic applications. The document forms a critical part of the standards landscape for wires used in transformer, motor, and coil manufacture, underpinning electrical insulation and reliability.

Key Topics

• Standardization of Winding Wire: The amendment fine-tunes requirements for polyesterimide enamelled round copper wire, which is widely utilized across electrical engineering for its excellent thermal and dielectric properties.
• Class 180 Rating: Refers to the insulation's ability to withstand temperatures up to 180°C, making it suitable for demanding environments found in modern electrical machines.
• Test Method Adjustment: Amendment 2 notably updates the approach to testing, replacing the clause on resistance to transformer oil with "Resistance to hydrolysis and to transformer oil," and marking the test as inappropriate for this wire type.
• IEC and CENELEC Harmonization: Developed through committee processes at the international and European levels, ensuring alignment in quality and safety requirements for manufacturers and users.

Applications

Polyesterimide enamelled round copper wires, class 180, are vital components in:

• Electric Motor Windings: Ensuring reliable performance in induction motors, commutator motors, and universal motors where high temperature resistance is necessary.
• Transformers and Coils: Used in power and distribution transformers, relay coils, and chokes due to their robust insulation and durability.
• Industrial Electrical Equipment: Supporting generators, solenoids, and actuators, where they help achieve space-saving, lightweight, and highly efficient designs.
• Consumer Electronics: Found in components requiring long-lasting thermal endurance and voltage insulation, contributing to device safety and longevity.

The impact of standards like EN 60317-8 and its amendments is to provide clear, unified criteria for manufacturers, purchasers, and certifiers, facilitating trade, conformity assessment, and safety compliance across the EU and globally.

Related Standards

• EN 60317-8:2010: The foundational document detailing specifications for polyesterimide enamelled round copper wire, class 180.
• IEC 60317 Series: The international basis for winding wire standards, covering various types, materials, and classes to suit a wide array of electrical applications.
• EN 60317-0-1: General requirements for winding wires, providing the overarching testing and classification framework.
• Other EN 60317 Parts: These include specifications for different enamel types, shapes (such as rectangular wires), and insulation classes, allowing for tailored selection based on application needs.

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 Int
