Overview

EN IEC 60851-1:2021/A1:2025 is an essential European standard providing general test methods for winding wires. Published by CENELEC in February 2025 as an amendment to EN IEC 60851-1:2021, this document ensures harmonization and up-to-date testing practices for electrical winding wires used across various industries. It aligns closely with the International Electrotechnical Commission (IEC) 60851-1:2021/AMD1:2025 standard and covers foundational procedures for evaluation of these critical components.

The standard applies broadly to winding wires, a key material used in electrical rotating machines, transformers, inductors, and other electrotechnical devices. As winding wires directly affect efficiency, safety, and durability, standardized testing guarantees performance consistency and regulatory compliance.

Key Topics

• General Test Methods: Defines the principles and scope of testing procedures applied to winding wires, setting uniform guidelines for accuracy and reliability.
• Amendment Details: Updates to the original 2021 edition include removal of redundant annexes and refinement of the scope, reflecting the latest technological advancements and testing insights.
• Periodic Conformance Tests: Clarifies that tests specified in related parts of the IEC 60851 series (Parts 2 to 6) serve as periodic conformance checks, emphasizing ongoing quality assurance.
• Standardization Process: Developed by IEC Technical Committee 55 with consensus from multiple CENELEC members representing numerous European countries, ensuring broad acceptance and applicability.
• Patent and Conformity Notes: Highlights intellectual property considerations associated with implementation while distinguishing IEC’s role from that of independent certification bodies.

Applications

EN IEC 60851-1:2021/A1:2025 applies to multiple industries and use cases, including:

• Electric Motor Manufacturing: Ensures winding wires meet performance and safety benchmarks critical for motor reliability.
• Transformer Production: Specifies test methods important for selecting wires that sustain thermal, mechanical, and electrical stresses.
• Electromechanical Components: Validates wire quality for coils, inductors, solenoids, and similar parts essential in power transmission and signal control.
• Quality Control Laboratories: Provides standardized testing frameworks for routine and developmental quality checks on various wire types.
• Regulatory Compliance: Supports manufacturers and suppliers in adhering to European and international electrotechnical regulations.

By following this standard, manufacturers enhance product consistency, improve durability, and minimize operational failures, thereby reducing costs linked with recalls or warranty claims.

Related Standards

EN IEC 60851-1 is part of the broader IEC 60851 series covering test methods for winding wires:

• IEC 60851-2: Tests for mechanical and electrical properties
• IEC 60851-3: Measurement of dimensions and thickness
• IEC 60851-4: Thermal endurance tests
• IEC 60851-5: Electrical tests for insulation resistance and dielectric strength
• IEC 60851-6: Tests related to resistance and electrical conductivity

These complementary documents expand on specific tests mentioned as periodic conformance evaluations in EN IEC 60851-1 and should be consulted for comprehensive test protocols.

By ensuring adherence to EN IEC 60851-1:2021/A1:2025, industry professionals can maintain international standards compliance, improve product quality, and support innovation in winding wire technology. For further technical guidance or procurement, stakeholders should consult authorized distributors or national electrotechnical committees listed on the CENELEC website.
