IEC 60317-20:2013

IEC 60317-20:2013 defines requirements for solderable polyurethane enamelled round copper wire, class 155, a winding wire used in electrical and electromechanical products where insulated conductors must perform reliably during manufacture and service. As the primary technical reference for this wire type, it supports technical review, procurement checks, and conformity assessment by describing the product category in a structured way. IEC 60317-20:2013 is relevant when teams need a clear compliance reference for selecting materials used in coils, windings, and similar assemblies.

Purpose of IEC 60317-20:2013

The purpose of IEC 60317-20:2013 is to specify the characteristics of solderable polyurethane enamelled round copper wire with a thermal class of 155, helping users assess whether the material fits a given engineering specification. It is typically used during documented evaluation, product validation, and technical assessment of winding wire intended for electrical equipment. By focusing on a defined wire construction and insulation type, the document supports consistent interpretation of supplier data and helps reduce ambiguity in quality workflows and compliance preparation.

Compliance applications of IEC 60317-20:2013

IEC 60317-20:2013 is commonly used in procurement review, laboratory evaluation, and verification activities for winding wire intended for coils, transformers, motors, and other wound components where solderability and enamel performance matter. It may also support technical documentation for manufacturers, test laboratories, and compliance teams that need to confirm material alignment with an engineering specification. In practice, it helps structure testing workflows, compare supplier declarations, and maintain operational consistency across product qualification and conformity assessment processes.

Benefits of IEC 60317-20:2013

Using IEC 60317-20:2013 can improve technical validation by giving organizations a defined basis for evaluating solderable enamelled copper wire against a recognized product description. This supports risk reduction in sourcing decisions, more consistent testing and acceptance criteria, and clearer communication between engineering, purchasing, and quality teams. It is also useful for regulatory preparation and certification-related documentation where a precise compliance reference is needed. For organizations managing electrical component specifications, it helps strengthen reliability, traceability, and procurement confidence.
