IEC 60317-20:2013/AMD1:2019 is an amendment to the requirements for solderable polyurethane enamelled round copper wire, class 155, and it is relevant where winding wire selection, specification control, and conformity assessment depend on clear technical documentation. Based on the official title, it supports engineering and procurement teams that need a reliable compliance reference for insulated copper wire used in electrical equipment. As a supporting document to IEC 60317-20:2013, it helps organizations keep technical files, verification activities, and product evaluation aligned with the current published requirements.

What is IEC 60317-20:2013/AMD1:2019?

This document is an amendment connected to IEC 60317-20:2013, updating the specifications for a particular winding wire type: solderable polyurethane enamelled round copper wire, class 155. In practical terms, it is used to interpret the current requirements that may affect design review, supplier documentation, and laboratory evaluation of winding wire used in coils and related electrical assemblies. For teams managing technical validation or regulatory preparation, IEC 60317-20:2013/AMD1:2019 is a useful supporting reference for maintaining operational consistency and technical compliance.

Applications of IEC 60317-20:2013/AMD1:2019

This amendment is typically consulted in workflows involving winding wire specification, component sourcing, and acceptance testing for electrical and electronic equipment. It may be relevant to manufacturers, test laboratories, and quality teams working with insulated copper wire intended for windings, where solderability and enamel performance are part of the technical assessment. During procurement review or conformity assessment preparation, IEC 60317-20:2013/AMD1:2019 can help define the document set used for product evaluation, supplier comparison, and controlled engineering documentation.

Why is IEC 60317-20:2013/AMD1:2019 important?

Using the correct amendment matters because winding wire requirements can influence product reliability, repeatable testing workflows, and acceptance criteria across engineering and quality assurance processes. IEC 60317-20:2013/AMD1:2019 helps organizations reduce risk by keeping specifications aligned with the latest published changes to the parent document. That supports more consistent technical review, better procurement decisions, and clearer evidence during conformity assessment, especially when verifying material suitability for class 155 applications and maintaining traceable compliance records.
