Specifications for particular types of winding wires - Part 20: Solderable polyurethane enamelled round copper wire, class 155
This part of IEC 60317 specifies the requirements of solderable enamelled round copper winding wire of class 155 with a sole coating based on polyurethane resin, which may be modified providing it retains the chemical identity of the original resin and meets all specified wire requirements. NOTE A modified resin is a resin that has undergone a chemical change, or contains one or more additives to enhance certain performance or application characteristics. The range of nominal conductor diameters covered by this standard is:
– Grade 1: 0,018 mm up to and including 0,800 mm;
– Grade 2: 0,020 mm up to and including 0,800 mm.
The nominal conductor diameters are specified in Clause 4 of IEC 60317-0-1:2013.

Overview
EN 60317-20:2014/A1:2019 is the CENELEC amendment to the international specification (IEC 60317-20:2013/A1:2019) for solderable polyurethane enamelled round copper winding wire, temperature class 155. This amendment (A1, published 2019) updates technical requirements-most notably solderability-and has been adopted as a European standard for national implementation across CENELEC members.
Key topics and requirements
The amendment replaces Clause 17 (Solderability) and establishes clear, testable requirements:
- Solder bath temperature: (390 ± 5) °C.
- Surface condition: tinned wire surface must be smooth and free from holes and enamel residues.
- Immersion time for soldering tests:
- For nominal conductor diameters ≤ 0.100 mm: maximum immersion time 2 s.
- For diameters > 0.100 mm: maximum immersion time is a multiple of the conductor diameter (mm), with a minimum of 2 s. Two grade options are defined:
- Grade 1: 8 s/mm
- Grade 2: 12 s/mm
Other relevant metadata included in the standard:
- Designation: Solderable polyurethane enamelled round copper wire, class 155
- Issued by IEC TC 55 (Winding wires) and adopted by CENELEC
- Implementation/withdrawal timelines noted for national adoption
Practical applications
This standard is intended for manufacturers, quality engineers and designers working with winding wires used in electrical and electromechanical components where solderability and high thermal class are required. Typical practical uses include:
- Winding wires for small coils, transformers, inductors and electric motors where solder connections are used
- Procurement specifications and incoming inspection criteria for enamelled copper wire
- Test procedures for production quality control and certification to temperature class 155
Using EN 60317-20:2014/A1:2019 helps ensure consistent soldering performance, reliable insulation integrity, and traceable acceptance criteria for solderable enamelled wire.
