Overview

EN 60317-35:2014/A1:2019 is a European standard developed by the CLC (European Committee for Electrotechnical Standardization) that specifies requirements for a particular type of winding wire. This standard focuses on solderable polyurethane enamelled round copper wire, class 155, with a bonding layer. It aligns fully with the international IEC 60317-35:2013/A1:2019 standard and details the technical criteria necessary to ensure high-quality performance for electrical winding applications.

The amendment A1 issued in 2019 updates EN 60317-35:2014 with key refinements, particularly related to solderability testing, ensuring consistent and reliable application in electrotechnical industries.

Key Topics

• Winding wire type: Solderable polyurethane enamelled round copper wire
• Insulation class: Class 155, meaning the wire can withstand temperatures up to 155°C
• Bonding layer: The enamel coating includes a bonding layer enabling solderability without enamel residues or holes
• Solderability requirements:
  • Solder bath temperature precisely controlled at (390 ± 5) °C
  • Maximum immersion time for wires up to 0.100 mm diameter: 2 seconds
  • For wires above 0.100 mm diameter: immersion time depends on diameter multiplied by a grade-specific factor (12 s/mm for Grade 1B and 16 s/mm for Grade 2B)
• Surface quality: The tinned wire surface must be smooth, free from defects and enamel residues after soldering
• Application scope: Specifies particular types of copper winding wire tailored for high-temperature electrical insulation and solderability

Applications

EN 60317-35:2014/A1:2019 standard is highly relevant to industries and applications requiring reliable winding wires with excellent solderability properties, especially:

• Electric motors and generators: Where copper winding wires must maintain insulation and solderability under thermal stress
• Transformers and inductors: High-class enamelled wires ensuring durability and stable electrical performance
• Electromechanical devices: Requiring precise winding wire specifications for enhanced mechanical and electrical reliability
• Electrical component manufacturing: Facilitates quality control in wires used for assembling coils and magnetic components
• Automotive and aerospace electronics: Where thermal endurance and secure solder joints are critical for safety and efficiency

The standard ensures that manufacturers and users can trust the winding wire’s performance, especially in environments where temperature resistance and soldering quality directly impact operational reliability.

When working with EN 60317-35:2014/A1:2019, consider referencing these related standards to fully address winding wire properties and testing protocols:

• IEC 60317 series: Covers various types of winding wires with different insulation classes and enamel formulations
• IEC 60505: Guidelines on testing methods for varnished and enamelled wires
• EN 60317-0: General requirements for winding wires used in electrical applications
• IEC 60216: Procedures for evaluating the thermal endurance and aging of insulating materials
• CENELEC standards: Cover additional electrotechnical components and materials harmonized across Europe

These complementary standards help integrate EN 60317-35 requirements into broader electrotechnical product design, manufacturing, and quality assurance frameworks.
