IEC 60317-21:2013/AMD1:2019 addresses an amendment to the specifications for particular types of winding wires, specifically solderable polyurethane enamelled round copper wire overcoated with polyamide, class 155. It is relevant where engineering teams, test labs, and procurement groups need a controlled technical reference for material selection, verification activities, and conformity assessment. As a supporting modification to IEC 60317-21:2013, IEC 60317-21:2013/AMD1:2019 helps organizations keep engineering documentation and compliance workflows aligned with the latest published requirements.

IEC 60317-21:2013/AMD1:2019 standard overview

This amendment is part of the IEC 60317 series for winding wires and is tied to the parent document IEC 60317-21:2013. Its role is to update or clarify the technical framework for solderable polyurethane enamelled round copper wire with a polyamide overcoat in class 155 applications. For engineering and quality teams, it functions as a compliance reference used in technical review, documented evaluation, and product validation where winding wire performance and specification control are important.

Applications of IEC 60317-21:2013/AMD1:2019

IEC 60317-21:2013/AMD1:2019 is typically used in workflows involving magnet wire selection, component procurement, and supplier documentation for electrical equipment that depends on insulated copper winding conductors. It may support laboratory evaluation, incoming inspection, and manufacturing controls for motors, transformers, coils, and similar electrotechnical assemblies where solderability and enamel systems matter. Organizations may also use it during technical assessment and review of material conformity against project or customer requirements.

Why IEC 60317-21:2013/AMD1:2019 matters

For operational teams, this amendment helps reduce ambiguity when verifying winding wire specifications and maintaining consistency across testing and procurement processes. It supports quality assurance by giving engineers and compliance specialists a clear reference for technical validation and conformity assessment preparation. In practice, using the current amendment can improve traceability, support risk management, and help align supplier declarations, inspection criteria, and engineering documentation with the parent specification and any updated requirements.
