IEC 60317-35:2013 defines requirements for solderable polyurethane enamelled round copper wire, class 155, with a bonding layer, making it a relevant technical reference for teams evaluating winding wire materials for electrical equipment. In procurement, engineering documentation, and conformity assessment, the document helps establish a common basis for product review, testing workflows, and supplier comparison. IEC 60317-35:2013 is especially useful where reliable insulation, solderability, and bonding behavior must be considered together during technical validation and quality workflows.

IEC 60317-35:2013 standard overview

This document belongs to the IEC 60317 series for particular types of winding wires and focuses on a specific round copper wire construction with polyurethane enamel and a bonding layer. Its likely technical purpose is to define a consistent reference for material characteristics, performance expectations, and evaluation conditions used in engineering and compliance activities. For organizations performing documented evaluation or technical review, it supports clearer specification control and more consistent comparison of winding wire products across suppliers and test reports.

Applications of IEC 60317-35:2013

The standard is typically relevant wherever enamelled copper winding wire is used in electrical and electronic assemblies, especially components that depend on compact coils, controlled insulation, and solderable terminations. It may be used in product evaluation, laboratory evaluation, and technical assessment for motors, transformers, inductive components, and similar electrical equipment. It also supports procurement teams and test laboratories that need a defined engineering specification when reviewing winding wire suitability for manufacturing or compliance workflows.

Why IEC 60317-35:2013 matters

Using a clear compliance reference for this wire type helps reduce risk during material selection, qualification, and conformity assessment preparation. The combination of solderability, enamel insulation, and bonding characteristics can affect assembly consistency, test outcomes, and long-term performance in electrical equipment. A defined technical document such as IEC 60317-35:2013 helps align suppliers, laboratories, and design teams on the same technical basis, supporting safer product evaluation, more repeatable verification activities, and better operational consistency.

• Specifies a particular winding wire construction for round copper conductors with polyurethane enamel and bonding layer.
• Supports engineering documentation and procurement review for coil and winding material selection.
• Useful for testing workflows that compare supplier declarations, sample behavior, and conformity assessment evidence.
• Helps standardize technical validation where solderability and insulation performance must be reviewed together.
