What is IEC 60317-7:2021?

IEC 60317-7:2021 is an international standard that specifies the requirements for winding wires used in electrical and electronic equipment. This standard covers the general requirements for enamelled round copper wires with a diameter ranging from 0.020 mm up to and including 2.000 mm. It provides guidelines for the production, testing, and performance of these wires, ensuring their quality and reliability.

Importance of IEC 60317-7:2021

The implementation of IEC 60317-7:2021 is crucial for various industries relying on winding wires, such as automotive, aerospace, telecommunications, and appliances. Compliance with this standard ensures that the wires used in these applications meet specific criteria regarding their insulation, thermal endurance, mechanical properties, electrical resistance, and dimensional tolerances. Adhering to these specifications guarantees the safe and efficient operation of electrical and electronic equipment.

Benefits of using IEC 60317-7:2021-compliant wires

Using wires that comply with IEC 60317-7:2021 offers several advantages to manufacturers and end-users. Firstly, these wires are manufactured with high-quality materials and under strict control, ensuring their consistency and reliability. Secondly, they provide excellent electrical conductivity, allowing for efficient energy transfer and lower power losses. Thirdly, the insulation system of these wires exhibits superior thermal resistance and compatibility with various environmental conditions, enabling their use in a wide range of applications.

Moreover, IEC 60317-7:2021-compliant wires undergo extensive testing to verify their performance and durability. This ensures that the wires can withstand mechanical stresses, temperature variations, and other operating conditions without compromising their electrical properties. By using these wires, manufacturers can enhance the overall quality and safety of their products, while end-users can benefit from improved performance, longevity, and reduced maintenance costs.


IEC 60317-7:2021 plays a vital role in standardizing the production and use of winding wires in diverse industries. By adhering to this international standard, manufacturers ensure that the wires used in their products meet strict criteria for performance, reliability, and safety. Compliance with IEC 60317-7:2021 provides numerous benefits, including enhanced electrical conductivity, improved insulation, and increased resistance to mechanical stress and temperature fluctuations. Ultimately, using these high-quality wires leads to more efficient and reliable electrical and electronic equipment.
